Phasor Measurement Unit Testing

Our power system nowadays operate as a huge complex machine that often operate close to their stability limit. This means that any disturbances or faults may cause power oscillations and lead to cascade outages. Many efforts, therefore, have been on the way to build new, smart grids. These will be the grids that use the most advance monitoring, controlling, networking, and measurement technologies. One of those technologies is a device known as Phasor Measurement Unit (PMU). PMUs are devices which produce synchronized phasor, frequency and rate of change of frequency estimates from voltage and/or current and a time synchronizing signal [1]. The key driver for PMU technology is the use of the precise time sources provided by GPS satellites to accurately measure the relative voltage and current phase angles at buses across interconnected grids [2]. This technology is capable of directly measuring the phase angles across an interconnected power grid, which is the main advantage that PMUs have over traditional SCADAs. In the thesis, PMU behavior and IEEE Synchrophasor standards have been studied through simulation and measurements. Simulation is done on a software platform whereas measurement is performed at a company, VSL, to test a PMU on its measurement quality.
