Phasor Measurement unit technology and its applications - a review

Now a days, there are several smart grid applications have been designed for the improvement of monitoring, protection and control of power systems in real time. Out of which most of the emerging approaches exploit the capabilities of wide-area technologies (wide area monitoring, protection and control - WAMPAC). Since WAMPAC implementation requires distributed phasor measurements throughout the system, phasor measurement units (PMUs) have to be adequately located depending on the real-time application. This paper addresses the Role of Phasor Measurement unit (PMU) technology and its application in the power system.
