2.3. EQUIPMENT USING NON-INTERRUPTION-FREE 230VALTERNATING CURRENT

It can be found all those installation elements in this device that, due to its way of

working, allow interruptions in the current supply without affecting its functioning.

These equipments receive the supply from the switching closet, the supply being previously filtered and stabilized. The equipments are fed from the tension coming

from overhead power cable, if this is present, and they are fed from network 2, when

there is a failure in the network 1. The equipments that are inside this device are:

• Air-conditionings

• Inside lights of buildings.

• Outside lights of buildings.

• Electrical installation of distribution in buildings.

• Water pump.

• System of sanitary hot water.

2.4. EQUIPMENT USING INTERRUPTION-FREE 400V ALTERNATINGCURRENT

The starting engines of the needles are fed with a 400-V three-phase tension between

phases (230 V between phase and neutral. Since the main source of supply – Network 1

– is single-phased it is necessary to install a static single-phase/three-phase converter. If

the mentioned converter fails, it is necessary to install an automatic electromagnetic

switching that feeds activations from network 2, in those buildings in which the it is

supplied from the public network, or it starts the emergency generator in those buildings

where it is installed.

2.5. EQUIPMENT USING DIRECT CURRENT

It is necessary to have an alternating current supply for the functioning of the signaling

equipments / telecommunication. This is supplied by a rectifier / service charger and

some stationary batteries free of maintenance with 60 minutes autonomy. A second

rectifier / emergency charger is added in order to grant the functioning of the

installation, which starts working when there is a rectifier / service charger failure.

2.6.SUPPLYING POWER TO IN-TRACK EQUIPMENT

For the supply of the signaling equipments and telecommunication installed on rails,

two armed cables will be laid from each technical building towards north and south to

an average point? of each stretch under its influence. These cables will be of the rightsection to the charge and length of the stretch, so that the supply within the margins of

each equipment is guaranteed. The cables of every stretch will en in a technical hut or in

a line closet. Energy cables from the two collateral technical buildings will go to the

technical hut or line closet, and the installation of the adequate equipment that allow to

supply the whole part from one technical building in case of damage or short circuit of

any of the two cables will be planned. For the supply of the equipments the cable should

go in and out of these without making T derivations in the gutter. This will allow, if it is

necessary, to cut off the cable to find short circuits. The equipments installed on rails

should have a transformer which reduces 750 / 230 V of the adequate power and should

be protected with the corresponding fuses, thermal-magnetic switches and protectionelements against high tension. In the same way they should have the terminals of

adequate section that allow the supply cable to be series connected.



2.7.SUPPLYING POWER TO MISCELLANEOUS RAILWAYINFRASTRUCTURE /TECHNICAL HUTS SUPPLY

The technical huts will have double supply. They will be supplied with 750 V tension

provided by the supply cable which is the main source, and they will also be supplied

from the overhead power cable tension, through a transformer in a post, as emergency

source.

Those consumers which are not signaling or telecommunications ones, such as air-

conditionings, lighting, etc, will be supplied with the overhead power cable tension.

An overhead power cable filter, a stabilizer, a transformer which reduces 750 / 230 V

ac, network automatic switching, static IAS with incorporated static by-pass and

batteries free of maintenance for a full charge autonomy of 15 minutes and insulation

transformers will be installed, for the equipments supply:

• Audio-frequency rail circuits.

• Routes counters. ?

• Signs.

• ERTMS markers.• Transmission system.

• Temperature control.

• Intrusion detection system.

• Fire detection system.

• Emergency lighting.

Two huts and only a tower will be installed in the GSM-R locations. One of the huts

will be for GSM-R, and the other one for public telephone operators. Thus, it will be

necessary to provide an electrical supply to both huts, also the installations, which

without occupying these huts physically, are electrically hanging from them, for

example, boosters and equipment inside the tunnels.

This project aims at resolving this need, as well as providing the necessary protection

elements to the system. Besides, given the redundancy determinants and security the

GSM-R installations require, the network design like a double layer, the double supply

from the overhead power cable and the 750 V ca line that passes through the gutter, it

has been also provided some batteries inside the huts to provide the important

consumers with a functioning backup. In the case of Operator installations, the need to

secure the supply is not so elevated, that is why there is not duplicity in intake supply,

but there are two lines, without the possibility of switching between them. Thus, given

the forecast consumption, the installation of a 10 kVA transformer for GSM-R and of

30 kVA for public telephone operators is necessary. Both transformers are described indetail in the corresponding overhead power cable section.

For both cases, and considering the high consumption produced by air-conditioning

compressors, these will be exclusively supplied by the line/s from the overhead power

cable.

In the GSM-R hut, due to the existence of equipments which consume electricity a –48

Vdc, it will be necessary the installation of an AC/DC rectification closet. Besides, it is

also necessary to provide the system fundamental elements with a supply backup, a

block of batteries and a DC/AC inverter will be also installed, for the consumers in 230

Vac with the need to secure the electrical supply.



2.8.PROTECTION AGAINST ELECTROCUTION/PEOPLE PROTECTIONAGAINST INDIRECT CONTACTS.

People who work with the electrical equipments described above have to be protected

against accidents caused by indirect contact with any of the tensions present in the

installation.

The inside equipments guarantee people protection against indirect contact through the

earth lead of all the accessible metallic parts of the electrical equipments. Inside the

same room it will be performed a ring connection of all the equipments and, at the same

time, this will be connected to the earth main bar, which is connected to the earth lead

of the electrical building and the earth rail. The security of the earth lead is guaranteed

by periodic inspections in all the connections on behalf of maintenance staff.

The outside equipments will be supplied by insulating transformers that guarantee the

separation of neutral and ground. The insulation between neutral and ground is

constantly supervised by supervisor equipment, which will say when the insulation

decreases up to unacceptable levels. The insulation will be guaranteed by regular

inspections of the supervisor equipment and the measured insulation, on behalf of themaintenance staff.

Experienced operators self-training interested in practicing their skills or learning new

functions.Examine the new functions of the network administration system

Verify changes in the network that affect the network structure, power stations, charge

behavior and network system dynamics.

Validate the structural changes in the power supply system, for example in the network,

in the power station, with the users or the dynamic system.

Evaluate preventing, patching and reconstructing measures that can happen while

normal functioning or in voltage situations.

Use the learning system as planning tools for network expansion.

7.2.3. Front-End Subsystems

Real-time data exchange with central control OCC is carried out by means of front-endservers, which are connected to the remote terminal units (RTU) through the running

LAN network of remote terminals. IEC 104 international protocol is used.

An IFS server does not constitute a special equipment. This is a UNIX from Sun server

that works with Front-End functionalities. This concept reduces the complexity of

software and hardware solution to its minimum, as well as the GIF maintenance and

training activities.

IFS servers are connected to a LAN network (IFS-LAN) at the Front-end end/tail. The

ISF servers are connected via LAN at the operation regional center and from there

connected to the OCC via LAN-ORP at the control central via LAN.

SINAUT Spectrum internal protocol is used to obtain the maximum real-time

performance.

The remote terminal units (RTU) will be connected to the independent Front-end

system (IFS) using the IEC 60870-5-104 protocol. This protocol is basically the same

IEC 60870-5-101 protocol encapsulated/packed in TCP/IP in such a way that possible

to use via LAN. These protocols are directly implemented in the IFS servers, so the use

of converters is not necessary.

The remote terminal units (RTU) will be synchronized using synchronization wires and

functionalities of different protocols. The timestamp will be set when the wire is sent

from the Front-end system to the remote terminal units.

Synchronization with the center OCC-ZAR (SAINCO System)The ICCP protocol is used in order to make data updating easier at the OCC-BAR with

the existing center OCC-Zaragoza and OCC-Downtown Zone.

7.2.4 Interfaces

SINAUT Spectrum has been designed and implemented as a SCADA system type with

special emphasis on open interfaces, of standardized access and easy communication. In

the GIF project SINAUT Spectrum provides the following interfaces:

8. REGULATION AND CONTROL CENTER

8.1. INTRODUCTION TO THE RCC

The scope of the offer includes implementation, supply and launching of an integrated

system at the Regulation and Control Center and two ORP.

The RCC system constitutes an integration platform of functionality and data mostly

regarding the real-time traffic operation and the GIF exploitation management.

The simulation environment for formation, sequence reconstruction and remote

monitoring are also supply object.

It is important to note that the global architecture of the RCC system is strongly

conditioned by the following requirements:

• An insulation level of the Real-Time Network that guarantees its safety against

external intrusions.

• Minimizing the latency of propagation of information from the real-time

network towards the rest of the networks.

• Replication and consistency of the real-time database and the relational

database.

Any system to be integrated in the RCC must have in its analysis, architecture, detailed

design and coding these basic requirements. In particular, from the point of view of the

security of the real-time control system, the integration of a system should not damage

the insulation degree that establishes the RCC architecture nor diminish its

provisions/performance.

The integration platform carries with it a series of resources, services and tools that

altogether are based on the integration of information principle and operability of

applications. In fact, the RCC platform has been conceived and specified by the GIF

from a global perspective, that merges the information and the control of the elements

that are part of the line, from the generation of exploitation plans to the real-time control



of trains, integrating all the systems of each of the techniques of this offer that part in

the operation and exploitation of the line:

• Centralized Traffic Control (CTC)

• Fixed and mobile communications integrated routing (DICOM)

• Remote power control (TE)

• ATP system central post (ERTMS)

• Complementing systems of monitoring and security (SCVS)

• Exploitation management and supervision (GSE) (it is part of SRC)

• Regulation help system (SAR) (it is part of SRC)

• Travelers information system (SIV) (it is part of SRC)

• …..

Each of these systems has its own central applications that we will name “native

application” (which will be the object of the corresponding section in “Detailed

description of the proposed solution”).

The complete integration of a native system in the CRC operation environment defines

a series of interfaces that can be broken up/divided in nine levels:

• User management

• Invocation of “native” applications

• Exchange of functional data through the messaging bus

• Administration and monitoring of adaptors to the messaging bus

• Management and supervision of the native system own systems

• Storing of supplementary data of analysis for sequences reconstruction

• Simulation

•Reconstruction

• Remote monitoring

Also from the CRC it can be accessed to management and technical supervision

applications of the computing infrastructure and of CRC communications:

• System management and supervision (GSS)

• Integrated management of networks and systems (GIRS)

Besides the CRC has its own applications, oriented to a global operation of the different

systems that forms it:

• Integrated management of users and control (GESUM)

• Integrated geographic window (VGI)

• Alarms integrated management (GIA)

• Communications integrated routing (DICOM)

All the native applications offer their information and functions relevant to the

integration applications (and even among/between them in some cases) for the global

operation, they are run from an only multi-system post (TEG), and they use ordinary

basic services: register and control of users access, time, storage, printing, etc.

Finally, it is necessary to describe the CRC from the work environment perspective:

• The own operation environment, also named Real-Time (RT)



• The sequences reconstruction and simulation environment, which is a

replica/copy of the RT operation environment oriented to formation, analysis

and situation reconstruction.

• The remote monitoring environment, that allows remote access to monitor from

outside the RT operation. Besides this environment, which is designated

Corporate, includes distribution services of and access to information comingfrom different sources. All these services are accessible from Intranet and

Extranet.
