Modified Application of Phasor Measurement Unit in Voltage Monitoring of Power System

Abstract

Application of Phasor Measurements Unit (PMU) in system monitoring and control has been receiving enormous attention in the power system industry nowadays. The availability of real-time synchronized phasor measurements offers unparalleled opportunities to expand the visibility of control centers and improve system reliability Utilities have taken important steps to incorporate PMU s into the key and critical load centers, and the output of the PMUs are used as an input parameter to special voltage protection and control schemes. The focus of this paper is on the recent work accomplished in the area of voltage monitoring and control by utilization of synchronized measurements received from PMU on the heavily loaded and critical bus.
