It is getting more important to acquire real-time synchronized phasor data of the power grid and make a correct operation, which cannot be done by traditional SCADA system.

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. With the high accuracy and high speed, WAMS also enables closed-loop control across wide geographic areas.

SIFANG’s Wide Area Measurement System detects abnormal system conditions, provides alarm message and analyzes results for system operator in real time. It is applied to improve the visibility and situational awareness in today’s and future power grids.
