Phasor Measurement UnitProvides

Real-time system monitoring for reliability and post event analysisControl for system components (e.g. FACTS, HVDC) Integration with existing SCADA/ EMS systemsInfo. to avoid blackouts like ones in the Northeast and WestSituational awareness on event locations and severityInfo. to facilitate system restoration after disturbance

SCE is working with WECC members and SCE neighbors like APS, SRP, PG&E, LADWP and WAPA for data exchange

Distribution Automation

New applications:Vacuum Fault InterruptersAutomated P/E (Auto Transfer)Automated Distribution RegulatorsIntelligent Fault IndicatorsDistribution Automatic Restoration SystemNetwork Protectors

11

Distribution Automation

All distribution automation presently accomplished through the use of CellNetUtilinet radios

Spread spectrum, peer-to-peerSome meter reading/ load survey functions will be replaced by Advanced Metering (SmartConnect™)

12

The Circuit of the Future (CoF)

SCE has identified a need to come up with new ideas to build more reliable and efficient distribution circuits

Provide customers with better serviceImprove safetyReduce costs
