3. Case Studies: WPC, EDF, WPD

DA Case Study: EDF, UKIntegrated SCADA functions to provide real time updates to operational diagrams and automation functions to the distribution network

The project … detection and rapid restoration of supplies when faults occur

The company … large distribution utility: 7.7m customers, 170,000km of network

The challenge … minimal additional investment in infrastructure

The solution … Identification of standard feeder configurations, creation of templates and scripting of Distribution Automation programs in the DMS master station

DA Case Study: Initial conditions

Starting Condition

- Feeder on Beach Stn is in normal state and has Automation enabled

-Normally Open point 641_ASP4 is Tie to adjacent circuit on Pine Tree Stn

- Normally Open point 641_ASP5 is Tie to adjacent circuit on a third substation

- Feeder on Pine Tree Stn is in normal State and has Automation Enabled

Primary CB Trips – Automation BeginsCB trips and locks out to

unsolicited open state

Automation Logic Triggers

- CB Event and Automation Start are logged to event log

- Automation symbol on diagram flashed to give visible indication of automation in progress.

- Automation traces circuit downstream from CB using current, not normal, network states to identify all Automated Devices

- Automation solicits current status from all automated devices on circuit.

Network updated to show dead section.

Fault location logic determines fault to be between 641_ASP2 and 641_ASP3

641_ASP2 identified as upstream sectionalize point

641_ASP3 identified as downstream sectionalize point

On confirmed successful open at 641_ASP3,

Fault is sectionalized

Determine Pre-Fault Load on downstream section using DPA values.

Determine available Tie points based on criteria

- Adjacent circuit has Automation Enabled

- Adjacent circuit is live

- Adjacent circuit capacity is greater than load to be transferred

Where more than one tie is available, they are prioritized by available capacity, highest first.In this example Tie 641_ASP4 is identified as the only available tie.

DA Case Study: benefits Some of the benefits of having Distribution Automation solutions deployed at the Master Station level.

Low cost … use of existing SCADA infrastructure

Adaptable … adapts to abnormal network conditions automatically

Protocol agnostic … no requirement for specific communications protocol

Performance targets … met performance targets early, $m financial savings

HV and EHV incidents account for 78% of CML (SAIDI)

Deployment … Deployed incrementally and quickly (1700 circuits / 18 months)

Power Analysis Case Study: WPC, AusIntegrated power analysis functions to check load prior to

switching during fault restoration and while writing planned switching

The project … implement power analysis on real time distribution system

The company … distribution utility: 1m customers

The solution … • Check load in real time immediately prior to switching• Check load pick up strategies during fault restoration• Check temporary feeding arrangement• Check switching plans at future date using load curves and temperature scaling• Adjust load flow scaling with SCADA• Calculate the network in the background

Power Analysis Case Study: WPC, AusIn 2006, WPC lost a zone substation in an important part of

Perth CBD. They used real time power analysis to safely restore customers.

The process … • power analysis used to check backfeed strategies• identified week feeder – 35% overloaded• load profile analysis identified load shedding at peaks

The outage … 10,000 customers without power including two hospitals

The outcome … • safely maximizing utilization of network asset• improvement in SAIDI & SAIFI (30% for this outage)• No media coverage

Mobility Case Study: WPD, UKMobile switching solution allowing control engineers to instruct switching plans to field crews and confirm operations direct from PDAs

The project … • reduce customer interruptions & SAIDI• more accurate reporting of times of operations• less Contention For ‘Control Function’ availability

The company … large UK distribution utility in South West England

The challenge … bleeding edge process untested elsewhere

The benefits … • reduced SAIDI due to field crew efficiencies as start job earlier• control room efficiencies due to reduced phone conversations• improved safety levels as fewer mistakes

4. Development path

Developments in mobilityMobile devices and communications technology are developing at a rate that allows a greater range of mobile applications to be deployed to integrate with DMS systems.

Field requests for safety check …Initiation of power flow “what if” studies prior to execution of switching steps

Field crew interaction … field crew writing of plans and checking of plans on PDAs and toughbooks in the field

GPS positioning & switching … confirmation of position prior to switching and routing to next operation

Transfer values …view spare capacity of radial feeders from open points to primary substation.

Distance to fault … fault current and topology can be taken as input to distance to fault to alert operator of likely location of fault on line.

Restoration advisor … provides suggested restoration programs where distribution automation cannot be implemented. Multi-objective optimization and look ahead.

Decision Support toolsA number of DMS decision support tools are emerging as data becomes available, sensor equipment improves and customer quality of asset data.

Voltage …display voltage drops through use of colours and / or contour lines to illustrate voltage drop off.

Single line view … dynamically generated simplified single line view of feeder so as to present key switchable sections

Geospatial layers… increasing options in presenting geospatial layered data to assist with understanding terrain

VisualisationThe interactive diagram will increasingly be used to present data in more useful formats, replacing tabular data with visual indicators.
