Implementation of Synchrophasor Monitoring and Event Analysis at American Electric Power

Abstract

The high sampling rate of phasor measurement unit (PMU) makes it possible to capture the power system dynamics and thus enables the real-time oscillation monitoring. American Electric Power (AEP) has deployed the Wide-Area Measurement System (WAMS) utilizing PMUs for years. This paper summarizes AEP's implementation experiences of real-time oscillation monitoring and post-event analysis with PMU data to enhance the situational awareness of power system.
