                                                Definitions

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
                             Page 3
                    Becoming 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 & 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 5
               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 Management

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

                              Repair 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 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 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 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 12
                        Impact 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?
