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.

Send Open Command to Upstream Sectionalize Point
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
Fault Location
On confirmed successful open at 641_ASP2,
Send Close command to Primary CB
Upstream Restoration
Send Open Command to Upstream 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.

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.
