Wide area monitoring systems

Definition

Wide area monitoring systems (WAMS) are advanced technologies used to monitor and manage the stability of electrical grids over large geographical areas. They utilize Phasor Measurement Units (PMUs) to collect real-time data on electrical parameters, allowing for better situational awareness and faster response to disturbances within the power system. By integrating data from multiple locations, WAMS enhances the reliability and efficiency of the grid.
