Practical testing and performance analysis of Phasor Measurement Unit using real time digital simulator (RTDS)

Wide Area Measurement Systems (WAMS) and Wide Area Monitoring, Protection and Control Systems (WAMPACS) have evolved rapidly over the last two decades [1]. This fast emerging technology enables real time synchronized monitoring of power systems. Presently, WAMS are mainly used for real time visualisation and post event analysis of power systems. It is expected however, that through integration with traditional Supervisory Control and Data Acquisition (SCADA) systems, closed loop control applications will be possible. Phasor Measurement Units (PMUs) are fundamental components of WAMS. Large WAMS may support PMUs from multiple manufacturers and therefore it is important that there is a way of standardising the measurement performance of these devices. Currently the IEEE Standard C37.118 is used to quantify the measurement performance of PMUs.
