System Dynamic Situation Awareness by WAMS

Wide Area Measurement System (WAMS) is built upon the break-through Phasor Measurement Units (PMU) technology.
It collects, stores, transmits and analyzes critical phasor data across the power grid.
WAMS provides power system state and situational awareness, which was impossible from the traditional SCADA system.
With the high accuracy, high speed and synchronized data, WAMS enables closed-loop control across wide geographic areas.
SIFANG delivered the first WAMS based wide area control system in the world, the HVDC modulation damping control.
