PMU implementation for a Wide Area Measurement of a power system

Communication between consumer and supplier in both the direction is the essence of Smart Grid. For such two way communication, advanced sensors are being used in the present grid to collect and analyze data from the grid network. Moreover, Critical events in the grid require real-time identification and real time response. Phasor Measurement Unit(PMU) is such an intelligent sensors which help in making the existing grid into intelligent, dynamic self-healing, self optimizing transmission and distribution grid. This paper presents an approach towards the Phasor measurement units which is less complex in design. With the recent development of technology in power systems, PMU's can play a key role in Wide Area Measurement System (WAMS) and thereby providing a new dimension to the power system monitoring. Out of various techniques used for Phasor estimation, Non-recursive DFT algorithm has been used in this paper since it is more stable. PMU is implemented and simulated in both software and hardware. It is designed with the help of NI LabVIEW software.
