  1. Distribution Automation (DA) & Distribution Management System (DMS)Initiatives Review Panel Presentation January 31, 2014

  2. Existing Automation Monitor and control equipment inside 15 substations: • Control Breakers • Control Transformers • Monitor equipment status (breaker opened or closed) • Measure electrical values (line loading) • Monitor equipment condition (oil temperature)

  3. Future Distribution Automation (DA) Control, monitor and automate equipment outside substations on the distribution system: • Improve System Reliability • Reduce outage duration • Reduce outage frequency • Improve Operational Efficiency • Improve Safety

  4. What is DA? Field systems that: Monitor equipment Remotely control devices Automatically detect and isolate faults Automatically restore electric service to customers What is DMS? • Software platformfor: • Demand response • Energy delivery optimization • Support Electric Vehicles and Solar Technologies • Other applications • DA systems will be integrated with DMS to further optimize systems operations

  5. Substation with Two Feeders

  6. Existing: Feeder Fault without DA • Breaker at the substation clears the fault • All customers on the feeder lose power • Crews need to patrol the entire length of the feeder to locate the fault

  7. Future: Feeder Fault with DA – Fault Isolation • Breaker at the substation clears the fault • DA locates the fault and isolates the faulted segment of the feeder

  8. Future: Feeder Fault with DA – Service Restoration • DA reconfigures feeders, closes the breaker and restores power to all unfaulted segments • Crews can be dispatched directly to the faulted segment

  9. Implementation Plan • DA initiatives: • Implement 10 distribution systems by 2019 • Install switches and communication equipment • Pilot test 2014/2015 • Project cost - $6.5M • DMS Initiatives: • Complete upgrading EMS in 2017 • DMS software implementation in 2019/2020 • Integrate with DA systems • Estimated project cost - $12M
