Laboratory for teaching synchrophasor measurements and applications

An experimental synchrophasor network and a set of instructions were developed for introducing synchrophasor technology and its applications to graduate and senior undergraduate students. In the laboratory setup, a power system simulated in a RTDS real-time digital simulator provides analog voltages and currents to phasor measurement units (PMUs). Time synchronizing signals for the PMUs are supplied from a GPS clock. The PMUs send synchrophasor data to a phasor data concentrator (PDC) through Ethernet, and the PDC provides outputs to applications. Students are allowed to test several applications such as phasor data visualization, transmission line parameter monitoring, and fault location.
