The City of Anaheim Public Utilities (Anaheim, California, U.S.) has completed the production deployment of the Advanced Control Systems' (ACS; Atlanta, Georgia, U.S.) PRISM Real-Time outage management system (OMS) to increase reliability and deliver improved electric service to its citizens.
ACS developed PRISM Real-Time OMS as a tightly integrated component of its comprehensive suite of smart-grid solutions for electric power utilities.
Anaheim operates its OMS from the same real-time database that supports its ACS SCADA, substation and feeder automation systems, resulting in lower data and system maintenance costs compared to traditional multivendor solutions. With its OMS, Anaheim has achieved faster outage prediction and restoration, streamlined switching operations, enhanced system visualization and improved safety for field crews and citizens.
ACS's PRISM smart-grid platform for OMS, DMS and automation can sustain more than 750 system events per second during storms, heat waves and other events that stress electrical distribution systems.
Anaheim serves 110,000 customers throughout a 50-sq-mile (129-sq-km) area, with a peak system demand of more than 580 MW. It operates 10 69-kV/12-kV distribution substations (with 17 69-kV transmission lines) and 105 12-kV distribution substations. A 50-MW combustion turbine generator is deployed for peak conditions.
