Synchronized Phasor Measurement System project at Southern California Edison Co

This paper presents the Synchronized Phasor Measurement Technology project at Southern California Edison (SCE). SCE has been working aggressively on this technology for the last four years and has installed several phasor measurement units (PMUs) and a phasor data concentrator (PDC) on its system. The data from the PMUs is now being collected and being used for analysis of system disturbances. SCE is continuing to work on this technology with Bonneville Power Administration to implement it for real-time monitoring and will work with other Western Systems Coordinating Council (WSCC) members for information exchange. It is believed that the technology has great potentials for monitoring the system stability and may be, useful in avoiding major system disturbances like the one that occurred on August 10, 1996 in WSCC.
