Implementation of wide area monitoring systems and laboratory-based deployment of PMUs

Abstract

Power systems are operating in a more complicated condition and therefore encounter more challenges. If one part of a power grid becomes seriously out of synchronism with the rest, the whole network can become unstable and blackout may occur. In this regard, we need to use advanced and smart monitoring tools to quickly and reliably observe the changing state of the key electrical parameters in real time, take appropriate corrective measures and isolate faults. Phasor Measurement Units (PMUs) by employing satellite technology, offer a state-of-the-art Wide Area Monitoring System (WAMS) for improving power system monitoring, control and protection. In this paper, we present information about WAMS components and requirements as well as description of work carried out in Brunel University laboratory to develop and implement a synchronized measurement system.
