Abstract
Synchrophasors are the measuring elements in which time is synchronized. In this electrical waveforms are represented by both the magnitude and phase angle. The Phasor Measurement Unit (PMU) is fast time-stamped equipment as it provides synchronized and accurate data. It measures voltage, frequency, current phasors, temperature and vibration for all the buses of the system. In the past decades many literatures are presented about the application of PMU. This paper presents a brief review of Wide-Area Monitoring Systems (WAMSs), PMUs, communication and data quality required for the utilization of PMU application in power distribution system as data quality and communication are the important parts of synchrophasor technology.
