Outage Management Basics
Some issues
Standards for Distribution Management
Page 3
A system of computer-based tools and utility procedures to efficiently & effectively -
•become aware of, •diagnose & locate, •provide feedback to affected customers•dispatch trouble/repair crews, •restore•maintain historical records of•compute statistical indices on
electrical outages
DefinitionsDefinitions

Becoming aware of outagesBecoming aware of outages
Customer telephone calls conventional human communication automatic voice response systems (CTI)
Auto outage detection/reporting systems SCADA detection of breaker trip/lockout Ideal: Become aware of outages before the
first customer calls in
Page 5
Diagnosing & locatingDiagnosing & locating
Grouping of customer trouble calls reverse tracing of electric topology determine a common protective device suspected to be open
transformer? lateral fuse? recloser? substation breaker?
Take into account automatic feeder switching
Compute extent of suspected outage Number of customers affected Highest priority of affected customers
Confirm or modify (split/enlarge) based on feedback from crews
Page 6
Feedback to affected customers Feedback to affected customers
Timely, accurate feedback is almost as important as fixing the problem Telling customer you are aware of his problem Current status of outage response Expected time of restoration
Page 7
Crew Dispatch ManagementCrew Dispatch Management
Computer-aided modeling of crews capabilities, tools, equipment real-time location tracking work load
Page 8
Repair and restorationRepair and restoration
Simple problems direct repair & restore
Major outages isolate fault & restore un-faulted portions of
feeder OMS tracks partial restorations
Automated Fault Detection, Isolation, Restoration schemes with feeder automation are considered desirable outside N. America
Page 9
Historical RecordsHistorical Records
Keep track of all outages root cause, number of customers, duration
Provides the data for Performance statistics SAIDI, SAIFI, CAIFI, etc Planning / budgeting maintenance activities
Condition based maintenance

Drivers for current interest in OMSDrivers for current interest in OMS
Customer expectations of reliability Momentary outages are also important The plague of electronic clocks!
Performance-based rates More likely a penalty for poor performance than a
reward for good performance!
Page 12
Data requirementsData requirements
Distribution Network Model getting an accurate electronic network model is generally a
mammoth under-taking Keeping it up-to-date with construction Real-time representation of switch positions
Customer data Customer - premise occupancy (business data) critical customers outage history Premise connectivity to Network model (operations data)
Timely, reliable feedback to affected customers during an outage
Page 13
Impact of De-regulationImpact of De-regulation
Separation of: energy provider energy delivery (poles & wires) Ancillary services (eg meter reading)
Increased interest in performance-based rates
Issues: Who does the customer call? Proprietary data issues?
