Outage Management Basics

Some issues

Standards for Distribution Management

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

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

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

Crew Dispatch ManagementCrew Dispatch Management

Computer-aided modeling of crews capabilities, tools, equipment real-time location tracking work load

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

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

Some issues


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!

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

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?
