Wide Area Measurement

Wide area measurement system is one of the new and widely introduced technologies in electrical power systems of the world.

Wide area measurement system (WAMS) and wide area measurement, protection and control systems (WAMPACS) take monitoring and control functions to a completely new level. WAMS provide a more detailed data on steady-state power system operating mode and transients, which arise due to different kind of power system failures. Therefore more and more facilities are equipped with phasor measurement units (PMUs).
