Foreword

This plan is System Operations (SO) roadmap in participation to transmission development of NGCP required to meet the objectives of its task: to operate and maintain the power transmission grid of the

country. This plan was envisioned in order to support the sustenance of the existing infrastructures, facilities, systems and equipment which are under the responsibility of SO. As a commitment for ensuring a reliable, efficient, economical and quality operation of the transmission Grid, NGCP will be investing to upgrade,

expand and replace existing infrastructures, facilities, systems and equipment. These upgrading, expansion and replacement initiatives are expected to enhance system and equipment performance and ensure the reliability,

security and quality of transmission service in the country.

This edition of the TDP Volume III will be released by System Operations (SO) and Metering Services Group. Part 1 will cover planned and developed capital expenditures relating to System Operations. Part 2 will cover

capital expenditures relating to Metering Services.

Chapter.01 Preliminaries

About System Operations System Operations (SO) functions, as the System Operator of NGCPs power transmission grid involve the management and operation of various power sources and transmission facilities. To carry out this function, SO is responsible in dispatching the proper loading of generating plants and dispatching transmission lines in order to achieve a secure and reliable power system. It also determines the appropriate configuration of the existing transmission network and other related transmission facilities at all times. This function covers the three major regions of the Philippines, namely Luzon, Visayas and Mindanao. In order to undertake the above services, SO operates and manages various facilities, infrastructure, systems and equipment strategically located in Luzon, Visayas and Mindanao which include among others:

1. National Control Center, Regional Control Centers and Area Control Centers. 2. Telecommunication network infrastructure. 3. Supervisory Control and Data Acquisition (SCADA) systems and equipment. 4. Information and Communication Technology (ICT) infrastructure. 5. Network Protection systems and equipment. For business management purposes, SOs obligations can be grouped into several key service areas described as follows:

1. System operations dispatching generation and managing the transmission system. 2. Power quality - providing the appropriate and acceptable level of quality electricity service in accordance

with the requirements set forth in Grid Code. 3. Grid reliability - ensure a secured and reliable transmission network, reliable infrastructure and efficient

system and equipment. 4. Market operations support - providing data, information and other support required by Wholesale

Electricity Spot Market (WESM) operations. 5. Maintenance and technical support - providing corrective and preventive maintenance services, operations

planning and technical services.

Structure of the TDP Volume III The 2010 TDP Volume III consists of two (2) parts. Part 1 contains the capital expenditure of System Operations while Part 2 contains capital expenditure related to Metering Services. Volume III: Part 1 is consists of development plan of System Operations as explains by several functional disciplines of System Operations, as follows: A. Telecommunication B. SCADA C. Protection D. Infrastructure E. SO Managed Equipment (SOME)

Each of these disciplines provides explanation of the development plans related to its respective capital expenditures:

a. Preface - describes the objectives and credible basis of the development plan. b. System Profile - describes the existing system profile by discussing and assessing the inventory, status

and conditions of systems and equipment. It also presents the current problems and issues. c. Requirement Analysis - discusses the additional requirements from various aspects that affect the

systems and equipment. d. Planning Criteria - explains the capital expenditures drivers on developing these program plans. e. Project Development - provides the discussions on how the capital expenditures were developed and

established. The capital expenditures describes in Volume III: Part 1 are totally independent from Volume I and II. These CAPEX projects covers the NGCP's proposed upgrading, rehabilitation, replacement, repair and/or maintenance of SCADA, Telecommunication systems, Infrastructure and System Operations (SO) Management Equipment used in the management of the national transmission and dispatching generation, including support to market operations and arrangement for ancillary services. It covers the plan for the upgrade, rehabilitation and replacement of secondary equipment/system for the planning horizon. It excludes those projects already integrated into the project package contained in Volume I and II for repair and maintenance including budgeting and procurement process of secondary protection system.

A. PREFACE Most significant among the System Operations (S.O.) assets is the NGCP telecom networkrepresenting over 80% of S.O.s present value (which also includes the SCADA/EMS system, network protection supervisory and test facilities, Grid operations tools and civil infrastructure). NGCPs private telecom network exists to meet operational needs mainly in the absence of responsive public infrastructure around its areas of operation and has proven to be the most secureyet most economicalmeans of servicing various mission-critical applications throughout the lives of its transmission line assets. Among other services, the NGCP telecom network provides communication facilities for line protection, SCADA/EMS, telephony, MIS/office automation and metering and billing applications. Because the pace of development vis--vis geographic peculiarities of the electricity Grids in Luzon, Visayas and Mindanao varied significantly, the characteristics of the respective telecom systems and facilities differ appreciably among each other. While Luzons attention is more on establishing and maintaining security of existing links, Mindanao is more concerned on yet putting up almost-the-most-basic communication access among it substations. Visayas, on the other hand, is midwayaiming to interconnect non-contiguous optical segments to build a more reliable backbone. As the open market integrates, the respective characteristics of the telecom networks in Luzon, Visayas and Mindanao become more similar as common performance parameters are adopted and the same operating philosophies are shared. The 2010-2019 CAPEX projects identified in this volume reflect this trend as an integrated NGCP telecom network develops over the course of the study period. A.1 Objective

Plan telecom network development within the next 10 years to support continuity of Grid operations and associated businesses;

Program addition, replacement, reconfiguration and retirement of telecom facilities in line with said network plan but excluding those telecom facilities programmed as complement for new T/L projects outlined in Volume 1.

A.2 Credible Basis

Power demand forecast and corporate thrusts defined in Volume 1, consistent with ERC references and guidelines;

Philippine Grid Code; ERC-defined asset lives of telecom network elements and pertinent qualifications by NGCP on

current applications.

B. SYSTEM PROFILE B.1 Statistical data

B.1.1 Luzon Existing Telecom Facilities

In Luzon, the telecom backbone has a general bandwidth of 155 Mb/s (STM1) with a fair number of segments operating at the higher capacity of 622 Mb/s (STM4). A combination of optical paths (embedded along the transmission lines) and microwave radio hops forms the said backbone, which also connects Luzon to Visayas and Mindanao via two (2) routesthrough Mindoro in the West and via Bicol in the East. Substations and offices which are not located along the backbone route are connected through spur links. Existing microwave radio spur links range in capacity from 8 Mb/s (4E1) to 155 Mb/s (STM1). There are also substation-to-substation narrow-band power line carriers (PLC) mainly to carry line protection signaling but which also provide low speed data or voice communication when there are no other cost-effective means to deliver such basic services (e.g., when the substation or power plant is located in difficult terrain). Bandwidth is optimized through the use of traffic managers such as the circuit-switched PABX systems (for legacy telephony and modem connections) and routers (for the modern IP-based applications). Operations and maintenance are organized through the use of network management systems and other remote sensing and supervision facilities; performance monitors ensure that the right quality of service is delivered. As an ultimate backup system, S.O. operates and maintains a UHF radio network in Luzon which also serves as mobile dispatch system for O&M in its transmission line maintenance activities.

NGCP also maintains telecom infrastructure in the form of the outside plant for the (transmission-line-embedded) optical links and PLCs, telecom antenna towers and radio repeater buildings. Table B.1.1 lists the major elements in the Luzon Grid telecom network indicating their respective conditions against current issues of concern.

While the SDH radios deployed in the backbone are below the ERC economic life of 15 years, 33% no longer have spare-parts support. Redundancy (1+1) protection is no longer available for some links due to lack of spares. Part of the installed base thus needs to be retired yearly to provide source of spares for the rest. As for the PDH, 47% of those within the ERC 15-year life are without spares support and forced retirement needs to be resorted to produce spares. Some PDH spur links are also filled to capacity and must be upgraded to accommodate additional applications through the service access points.

B.1.2 Visayas Existing Telecom Facilities

Visayas telecom backbone operates at a bandwidth of 155 Mb/s (STM1). A combination of optical paths (embedded along the transmission lines) and microwave radio hops forms the said backbone, interconnecting the island sub-grids of Leyte, Cebu, Negros, Panay and Bohol. The backbone links Luzon via Panay in the West and via Leyte in the East; Mindanao is connected from Negros through the island of Siquijor at the Southernmost tip of Visayas. Substations and offices which are not located along the backbone route are connected through spur links. Existing microwave radio spur links in Visayas range in capacity from 8 Mb/s (4E1) to 32 Mb/s (E3). There are also substation-to-substation narrow-band power line carriers (PLC) mainly to carry line protection signaling but which also provide low speed data or voice communication when there are no other cost-effective means to deliver such basic services (e.g., when the substation or power plant is located in difficult terrain). Bandwidth is optimized through the use of traffic managers such as the circuit-switched PABX systems (for legacy telephony and modem connections) and routers (for the modern IP-based applications, which now include VOIP and SCADA/EMS communications). Operations and maintenance are organized through the use of network management systems and other remote sensing and supervision facilities; performance monitors ensure that the right quality of service is delivered. NGCP also maintains telecom infrastructure in the form of the outside plant for the (transmission-line-embedded) optical links and PLCs, telecom antenna towers and radio repeater buildings.

B.1.3 Mindanao Existing Telecom Facilities

Mindanaos telecom backbone operates at a capacity of 32 Mb/s (E3). The microwave-radio-only backbone connects to Luzon and Visayas via a radio hop between Iligan and the Visayas island of Siquijor. Substations and offices which are not located along the backbone route are connected through spur links. Existing microwave radio spur links range in capacity from 4 Mb/s (2E1) to 32 Mb/s (E3). There are also substation-to-substation narrow-band power line carriers (PLC) meant to carry line protection signaling but which also provide low speed data and voice communication in the absence of microwave radio spur links. Bandwidth is optimized through the use of traffic managers such as the circuit-switched PABX systems (for legacy telephony and modem connections) and routers (for the modern IP-based applications). Operations and maintenance are organized through the use of a network management system; performance monitors like the LAN/WAN bandwidth manager ensure that the right quality of service is delivered. As an ultimate backup system, S.O. operates and maintains a VHF radio network in Mindanao which also serves as mobile dispatch system for O&M in its transmission line maintenance activities.

NGCP also maintains telecom infrastructure in the form of the outside plant for the (transmission-line-embedded) optical links and PLCs, telecom antenna towers and radio repeater buildings.

C. REQUIREMENTS ANALYSIS

Grid expansion, current business demand, technology direction and the need to replenish equipment to sustain operations are the bases for which we have determined our requirements within the course of the study period 2010-2019. C.1 Transmission Grid Extension

Telecom requirements as a result of transmission grid extension are addressed through the telecom components of transmission line projects defined in Volume 1.

There are, however, deficiencies in existing telecom facilities which were a result of

under-programming of the necessary telecom complements in previous or current transmission line expansion projectsthe appropriate adjustments to reverse such deficiencies shall be included as among the requirements in this program.

This volume does not include provisions for interconnections of new customers

anticipated or notgiven that the program for such customer-specific facilities are governed by a separate mechanics.

C.2 Corporate Business Needs

Current business requirements vis--vis the state of pertinent telecom facilities are assessed in the following tables. The telecom elements are further analyzed according to four (4) basic parameters of the service: capacity (or bandwidth), route protection (or security), network reach and traffic management.

traffic management systems to optimize backbone bandwidth. We may assume from the following graph that the capacity of the existing backbone is just enough to meet NGCP applications demand without the need to expand within the next 10 years. (That is: there is no over-capacity in NGCPs backbone.)

25

Figure C.2.1 Telecom Demand Analysis, 2010-2019

However, as we have discussed above, bottlenecks in the existing service access pointsi.e., network connections to the plants/substationsprevent remote nodes from optimizing use of the backbone bandwidth. Thus, in ensuring adequacy of capacity of the network to carry applications demand, continuity of the desired bandwidth should be established by providing the appropriately-sized spur links. As much as the need to provide sufficient bandwidth, the need for alternate (1+1) physical paths for important network nodes should also be addressed in establishing a resilient-enough telecom transmission system. In NGCPs SDH network, a general deficiency in this area is manifested in the absence of physical ring protectionmainly because of the need to still retrofit OPGW in old transmission linesintended to prevent traffic loss in case of single-point failures (e.g., cut OPGW, power supply outage in a common node). Following is an illustration of a non-protected versus ring or 1+1 protected optical network connection.

C.3 Technology Evolution

Consideration of the effects of technology trends in programming facilities to meet applications demand is important in our effort to optimize returns by availing of the most efficient technology which will deliver the required services, avoiding early obsolescence, selecting which standards and policies to adopt and determining how to adapt existing processes with the anticipated changes in the business environment.

D. PLANNING CRITERIA

The facilities program meant to meet needs identified in our requirements analysis above shall be governed by the following philosophies and policies consistent with corporate mandate.

D.1 Technology Philosophy

Decision to adapt to technology directions should be weighed against impact on core

business vis--vis economics. Reliability and security precedes functionality.

Adopt open-systems standards in management, traffic processing and interfacing to

increase flexibility to technology shifts and changes in organizational models as well as to optimize access to best of breed.

Prefer green technology as part of corporate social commitment.

D.2 Technology Development Route

Network infra shall continue to accommodate and prioritize real-time channels

allocated for grid protection signaling. To optimize bandwidth, IP-based traffic management facilities shall be established and

switched-circuit traffic managers shall be gradually retired.

IP telephony shall be implemented hand-in-hand with the shift in traffic management paradigm to optimize infra utilization.

Routing protocol shall be migrated from proprietary to open systems to take

advantage of the increasing prevalence of routing functionality in modern telecom facilities.

The energy-efficient (and generally cheaper) split-type radio technology shall be

adopted where feasible (e.g., for up-to-STM1 radio links) to optimize radio transmitter power, eliminate waveguide-caused problems and minimize dependence on air-conditioning requirements (and reduce failure rates resulting from lack thereof).

ADM (add-drop-multiplexing) and terminal functionalityas well as application access

capabilityshall be incorporated in new SDH nodes to limit failure points and maximize manageability.

D.3 Policies

Philippine Grid Code Protection Philosophy

Spare Parts Management Policy

Government regulatory policies on use of radio frequency spectrum

29

Network security policy: physical separation of SCADA and protection networks from admin/MIS network

E. PROJECT DEVELOPMENT

Implementation of the facilities plan requires that the most efficient mode and scale of asset acquisition be established as basis for the CAPEX program. Both new projects and replenishments involve planning for service lives of assets according to anticipated optimum generated values from depreciation, with due consideration to established factors of safety.

E.1 Guidelines

Infrastructure components shall be dimensioned to meet expected growth in requirements up to the end of expected economic lives.

Facilities shall be dimensioned according to an 85% fill of expected maximum capacity for contingency.

Replacements of operational network components shall be phased such that there is

minimum traffic interruption.

Turnkey implementation (i.e., through Work Orders) shall be employed where:

(1) Projects cannot be carried out using existing resources, or (2) There is a need for technology transfer.

Replenishments/ upgrades of network components that have exceeded economic lives

shall be implemented using in-house engineering resources (i.e., shall be procured as GPE) to minimize implementation time and synchronize construction with operational priorities.

For purposes of depreciation programming, CAPEX projects shall be classified as:

(1) Expansion : New Asset (2) Upgrade/Rehab : Add Value to Existing Asset (3) Replacement/Replenishment : Replace (Depreciated) Asset

E.2 Economic Analysis

Purpose: since telecom projects of NGCP are indirectly productive (i.e., with no definitive marketable outputs), economic analysis aims to establish the least-cost option in delivering the required services.

Alternatives from which to determine optimum allocation of resources are defined according to the following aspects:

30

(1) Method of project implementationi.e., turnkey or in-house; (2) Means of establishing and sustaining facilitiesi.e., lease or own; (3) Distribution of benefits; e.g., which technology offers the flexibility to

accommodate the most applications and satisfy the most operational objectives using shared infrastructure.

E.3 Safety and Security Concerns

For maximum security, physically separate networks shall be provided for both teleprotection and SCADA applications.

Repeater station security systems shall be reinforced to protect telecom backbone integrity.

Long-haul optical links shall preferably employ the use of the more physically-secure

transmission line-embedded fibers, such as in OPGW and OPPC, over ADSS (given current experience in ADSS maintenance).

Telecom towers shall be constructed with utmost consideration in the safety of

maintenance personnel; retrofitting of safety facilities shall be addressed where necessary among existing towers.

E.4 Specifications Program (General Principles)

31

Table E.4.1 Specifications of Major Network Elements, 2010-2019

ELEMENT 2010 2019 RATIONALE 1. Backbone

Capacity STM1 (155Mb/s)

STM1 (155Mb/s)

Forecasted demand by 2019 is about 120Mb/s only; (expensive) higher capacity implementation in M/W radio segmentswhich comprise significant portions of the backbonewould be premature (i.e., not cost-justified)

2. OPGW 24 Cores 48 Cores Only about 4 cores max allotted for dedicated relay communication but rapidly decreasing difference in installed cost of higher-density OPGW warrants increase in fiber cores; mechanical and electrical parameters limit size variance, though

3. M/W Radio Spur Links

4E1~E3 E3~STM1 Primarily because of the need for separate SCADA, admin and protection IP networks, higher capacity tributaries are needed

4. SDH Topology

Flat Ring Physical Ring Physically redundant (1+1) paths would provide required telecom backbone security

5. Sync System GPS GPS GPS was the original choice for synchronization because of its relatively cheap cost of implementation and maintenance vis--vis the proven reliability

6. WAN Topology

Partial Mesh Full Mesh IP Path redundancy would optimize access to SCADA, protection and MIS nodes by avoiding single points of failure

7. IP Bandwidth Management

Shared Network

Physically separate networks

SCADA, Protection and Admin/MIS shall have physically distinct networks for optimum security

8. PABX/ Telephony

Circuit-switched

IP Legacy telephony switches will be gradually replaced by IP-based systems to maximize bandwidth efficiency and simplify traffic management

9. Protection Signaling Equipment

Priority-coded

Simultaneous independent commands

To ensure integrity of discrete protection signals and simplify analysis of events, new PSE shall be specified with independent signal processing per port

10. IP Routing Proprietary (CISCO)

Open Systems Migration from EIGRP to OSPF would optimize utility of telecom facilities (equipped with routing function), simplify (hierarchical) network management and reduce costs of ownership

P R E F A C E

SCADA systems have been employed as indispensable tools for safely and securely operating the Philippine grid. Data acquisition equipment installed in power plants and substations not only continuously feed data to the control centers, but provide remote control capabilities to devices installed in the field.

Real-time information from the remote stations as presented by SCADA provide instantaneous picture of the ever-changing conditions of the power system thus enabling the system operators to make timely decisions and actions.

B.1.1 OBJECTIVES

The TDP programs have been developed with the following objectives:

1. to sustain the performance and reliability of installed data acquisition and control center systems, including the updating of system software,

2. to expand the functionality and capability of the SCADA system and equipment in order to meet new requirements of the grid and electricity market system,

3. to enhance installed system to support increasing stringent corporate performance targets.

These programs identified in this TDP are geared towards the continuing effort to maintain performance levels of existing SCADA systems and facilities through regular maintenance, planned replacement of failed, obsolete and unsuitable facilities, and acquisition of new facilities to support requirements for operations and address performance deficiencies and new functionalities.

B.1.2 CREDIBLE BASIS

Regulatory and Statutory Requirements

NGCPs commitment towards complying with the following applicable regulatory requirements is one of the major drivers for the SCADA CAPEX programs:

Philippine Grid Code (PGC), Open Access Transmission Service (OATS), Wholesale Electricity Spot Market Rules (WESM Rules) and, Directives from the Department of Energy (DOE) , Energy Regulatory Commission

(ERC) and other government agencies.

NGCP Transmission Master Plan (2009-2030) and 2010-2019 TDP Volume 1

Anticipated additions to power plants and substations as outlined in NGCPs short, medium and long term plans provide inputs to SCADA requirements in the upcoming period. Although associated data acquisition equipment are usually included in theprojectsfornewplants and substations, these additions also impose requirements on the master stations and affect other existing equipment and systems.

ERC Economic Life of Major High Voltage Electrical Equipment

The Sinclair Knight Merz (SKM) study in 2006 on the economic life of electrical equipment provides the general basis for the replacement plans of SCADA equipment.

While ERC has adopted a fifteen-year economic life for SCADA based on the above study, this should be considered as referring to the entire SCADA system. Individual components have various applicable economic lives depending of the type of equipment and the environment in which it is operating:

SCADA computer hardware - IT-type equipment which have an industry-accepted service life of five (5) years. For hardware used continuously in a harsh environment, service life deteriorates fast.

SCADA software - software do not suffer physical degradation, however its life is shortened with technological development which make it incompatible to new hardware and the subsequent withdrawal of support from the software developer.

Data Acquisition Equipment being designed for the substation environment, these follows the standard economic life of fifteen (15) years, except for IEDs where active components last only for ten (10) years.

Auxiliary Equipment similarly, power equipment generally have about fifteen (15) years service live. Sealed maintenance-free batteries are replaced every three (3) years, their service life severely affected by discharged duty and operating temperature.

SCADA systems are designed according to specific system requirements to match the existing power system. Power system expansions require corresponding SCADA expansions. Accumulated expansions may require accelerated replacement even if the SCADA is still operating within the service life.

NGCP Control Center Hierarchy

NGCP maintains a hierarchy of control centers to support operations of the nation-wide transmission system with the dispatch of all generation facilities connected to the Philippine grid. This hierarchy consists of three (3) levels:

1. National Control Center. The National Control Center (NCC) in Diliman, Quezon City coordinates all high-voltage transmission operations (300 kV HVDC, 500 kV, critical 230 kV and 138 kV circuits) and dispatch all generation. A Backup National Control Center (BNCC) has been established at Cebu City.

2. Regional Control Centers. The RCCs are responsible for monitoring and control of non-

critical 230 kV and 138 kV transmission systems in each of the three power grids: Luzon, Visayas and Mindanao. The Luzon RCC is co-located with the NCC, and the Visayas RCC with the BNCC. The Mindanao RCC is responsible for the operation of the Mindanao grid.

3. Area Control Centers. To supervise other parts of the transmission network not

managed by the RCCs and coordinate directly with the customers, Area Control Centers are established all-over Luzon, Visayas and Mindanao.

B.2.1.1 Luzon SCADA

Luzon EMS Profile

After eight year in operations, the existing GE XA/21 EMS at the National Control Center (NCC) is being upgraded to address deficiencies in performance and reliability, to support expanded database requirements and to include new functionalities required by Market Operations. The upgrade will be completed by 2011.

A back-up control center with limited functionality is currently operating at the Araneta S/s using Realflex SCADA software.

Luzon ACC SCADA systems Profile

The four (4) ACCs in Luzon use remote consoles that connects to the NCC EMS. The availability of these ACCs is dependent on the EMS and the communication links between NCC and these ACCs.

Under the NCC EMS upgrade, a back-up EMS will be installed at the Central Luzon ACC in Mexico, Pampanga. The ACC remote consoles will also be upgraded.

As part of this TDP, Luzon ACCs will be provided with stand-alone SCADA systems for independent and more reliable SCADA operations.

Luzon MBSC Systems Profile

Eleven (11) MBSC systems in Luzon are operating as originally designed and seven (7) are now due for upgrading/replacement. These systems are supplied by different manufacturers making maintenance difficult. Of the seven systems that are due for upgrading/replacement, four are being implemented by SO, two are handled by P&E group and one is being handled by O&M group.

New MBSC system for Dolores (Taytay) Substations is in the process of acquisition by the O&M group for the year 2010.

Luzon Data Acquisition Equipment Profile

Almost all remote terminal units in Luzon use GE D20 RTUs. Most of these RTUs have been upgraded in 2006 to support new protocols. Communications capability for these RTUs is limited to direct serial connection. A few RTUs still use analog communications link with bandwidth as low as 1200 baud. Most RTUs reports to the master stations using Harris H5000 protocol. Only few RTUs use DNP V3.0 protocol.

With the development pointed towards IP-based communication systems, programs to upgrade the existing RTUs to support IP-based connections have been included in the 2010-2019 TDP.

B.2.1.2 Visayas SCADA

Visayas EMS Profile

The EMS used at the Visayas RCC is identical to the NCC EMS and is intended to be the back-up for NCC in case of NCC unavailability. Together with NCC, this EMS is undergoing upgrade to improve system performance and reliability.

A back-up control center is operating at the Mandaue S/s using Realflex SCADA software.

Visayas ACC SCADA systems Profile

The four Visayas ACCs use Realflex SCADA system software which have been installed in the nineties have undergone series of upgrades for software versions and hardware. Upgrade for the replacement of obsolete hardware is still on-going and will be completed by the end of 2010.

After having been in operations for a long period, the ACC SCADA Systems are scheduled to be replaced in 2013.

Visayas MBSC Systems Profile

Visayas have MBSC systems supplied by ABB, Siemens and Areva. Two systems are based on the D20 RTUs and DAPservers and use Realflex SCADA as the HMI software. The MBSC at Sta. Barbara SS is currently undergoing upgrading.

Most MBSCs in the VIsayas have been programmed to undergo upgrading involving mostly hardware and minor software upgrades every five (5) years.

Visayas Data Acquisition Equipment Profile

Almost all RTUs in the Visayas are GE D20 RTUs, mostly installed during the early nineties. The main board and some peripheral boards were upgraded in 2006 for higher performance and support to more protocols. The RTUs are programmed for upgrading to support communications through TCP/IP networks in the future.

Visayas Auxillary Equipment Profile

Operations of SCADA equipment are dependent on auxillary equipment like UPS, DC power supply, batteries and emergency generators. These equipment typically have longer life spans. Some equipment are programmed for replacement in this TDP.

B.2.1.3 Mindanao SCADA

Mindanao EMS Profile

The Mindanao SCADA/EMS is presently under upgrading after a fire in 2009 destroyed their previous EMS.

A temporary Siemens Spectrum WinCC SCADA system with limited capability was hastily set-up and presently used to support dispatch engineers in operating the Mindanao grid. This system cannot fully support the needs for operations since it is only capable of basic SCADA functions and do not have advanced applications like Automatic Generation Control (AGC) and network applications.

Mindanao ACC SCADA systems Profile

Mindanaos five ACCs have stand-alone Siemens Spectrum WinCC SCADA systems installed in the past three years. These systems are non-redundant units with the SCADA applications and HMI running under a single hardware. Like the temporary system used at the MRCC, these SCADA systems only have basic SCADA functions and do not support advanced functionalities.

Mindanao MBSC Systems Profile

There is still no MBSC being used for operations in Mindanao. Although the Pitogo system has already been tested and commissioned, it is not actually used because there are still no transmission lines going into the substation. The other MBSCs are still under P&E construction. However, two systems are already of deteriorated conditions because they have been delivered many years but and have not been installed. MBSCs in Mindanao are supplied by Siemens, ABB and Areva.

Mindanao Data Acquisition Equipment Profile

Telegyr Station Manager RTUs are used mostly in Mindanao. These RTUs have been upgraded in 2008 for additional communication ports to new master stations and support DNP V3.0 protocol. A few GE D20 have been installed in some power plants. These RTUs only support serial connections to the master stations.

Originally transducers were installed in the nineties for providing power system information to the RTUs. Since 2004, transducers are being replaced with Intelligent Electronic Devices (IEDs).

B.2.2 Problems and Issues

In the operations of NGCPs SCADA systems, the following problems and issues are frequently encountered that limits the performance of the systems:

Limited operating life of hardware:

Although IT equipment typically have service lives of five (5) years, in the environment where these equipment are used in SCADA systems, actual operating life is usually shortened to about three (3) years due to continuous and heavy demand on the processing power of these equipment, and the harsh operating environment specially for computers used in substation automation.

This usually results in high maintenance costs for replacement hardware.

Fast Obsolescence of Computer Hardware and Limited Support for Legacy Systems due to Rapid Technology Development

After a few years, replacement parts or even equipment are no longer available because these hardware are already not manufactured. To make matters worse, new hardware models are usually not compatible with other old equipment.

When new models and system versions are introduced in the market, the manufacturer usually withdraws support for these systems a few years there-after.

Insufficient capacity to support rapid power system expansion:

The rapid construction of power plants and substations and the fast expansion of the power grid through the introduction of additional transmission lines and equipment have put a tremendous strain on the performance requirements of existing SCADA systems and data acquisition equipment.

Proprietary Requirements for Multi-vendor systems

NGCP has employed SCADA systems and equipment supplied by different vendors. The proliferation of different systems complicates the requirements for NGCP in terms of spare parts and technical proficiency in maintaining, expanding and upgrading the systems.

In addition to these operational issues, planning for SCADA requirements are hampered by unresolved policies on compliance to certain PGC requirements:

SCADA Monitoring Requirements at Customer Connection Points: SCADA Monitoring for Embedded Generators

B.3 R E Q U I R E M E N T A N A L Y S I S

B.3.1 TRANSMISSION GRID EXTENSION

Additional SCADA/EMS requirements usually result from transmission grid extensions and power plant additions. Transmission expansion activities are identified in the Volume 1 of this Transmission Development Plan as developed by NGCPs P&E group.

Major SCADA requirements for new stations are usually incorporated in the design of these new stations and are provided under the P&E projects. This however only addresses the SCADA requirements for remote sites. Corresponding equipment additions and capability expansions also required at the master stations are usually not included in the scope of these projects.

On an individual station basis, these requirements may be addressed by the addition of expansion modules and reconfiguration of the existing system. The corresponding requirements at the master stations will only be incremental for a few individual stations.

Overtime, accumulated expansion requirements may reach the point where the capacity may no longer be supported by the existing master station system. This results in accelerated need for system replacement programs.

Small scale substation expansions are implemented by NGPs O&M group, like additional circuit breakers, etc. These expansions require only additional RTU boards for new I/O
