GE to provide SoCalEdison with system for early threat detection

GE (NYSE: GE) will be providing Southern California Edison with a Phasor Measurement System designed to help quickly identify any potential problems with its grid.

The project, which is also known as a wide-area situational awareness system, uses phasor measurement units to measure underlying grid conditions at a rate of 30 times per second, according to GE. Traditional SCADA systems acquire measurements every two to 10 seconds.

The project will deploy PMU devices in 500 kV and 230 kV substations through SCE’s network and will integrate the devices with situational awareness applications at the grid control center. According to GE, the solution will provide “real-time monitoring of power flows, voltage magnitudes and phase angle differences between utility substation busses as well as frequency and its associated rate of change.

The system can also be supplemented with information from energy management system and non-electrical system data, which could include information on weather and traffic conditions or information on earthquakes or fires.

“GE is providing an EMS-like platform that combines synchrophasors with other sources of information to enhance wide-area situational awareness in real time,” said Michael Carlson, general manager—software solutions for GE’s Digital Energy business. “Our phasor system will enable SCE to complete phase one of the project by exchanging synchrophasor data with the Western Electricity Coordinating Council and its member utilities.”
