Some issues

Standards for Distribution Management

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
Page 4
Diagnosing & locating

Grouping of customer trouble calls


reverse tracing of electric topology
determine a common protective device suspected to be
open






Take into account automatic feeder switching
Compute extent of suspected outage



transformer?
lateral fuse?
recloser?
substation breaker?
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
Page 6
Crew Dispatch Management

Computer-aided modeling of crews



capabilities, tools, equipment
real-time location tracking
work load
Page 7
Repair and restoration

Simple problems


Major outages



direct repair & restore
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 8
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!
Page 11
Data requirements

Distribution Network Model




Customer data





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 - 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?
