GE says Southern California Edison (SCE) has called on the company to provide a centralized remedial action scheme (CRAS) solution to facilitate the operation of multiple remedial action schemes (RAS).

Operating in conjunction with GE's previously installed XA/21 energy management system, the CRAS will detect abnormal conditions on the power grid and automatically select and initiate the appropriate high-speed control action in order to preserve grid stability and protect key elements of SCE's transmission network, according to GE.

SCE's current distributed RAS manage the operation of its electrical grid following the loss of one or more transmission lines. GE says the CRAS project will improve the efficiency of SCE's transmission grid operations by centralizing the control logic for the various RAS in one location, resulting in reduced commissioning costs, maintenance efficiencies and more effective processing of generation interconnect requests designed to meet renewable energy portfolio targets.

The project, spearheaded by GE, will utilize a SISCO controller to carry out algorithms for the RAS and will feature an advanced communications network from Cisco. These two components work hand in hand with GE’s XA/21 system to create a real-time control framework, GE adds.
