Opis

The phasor measurement unit (PMU) is considered to beone of the most important measuring devices in thefuture of power systems. The distinction comes fromits unique ability to provide synchronized phasormeasurements of voltages and currents from widelydispersed locations in an electric power grid. Thisbook addresses two major challenges attendant to thistechnology: PMU device placement and applications. Itteaches how to complement PMU data with decisiontrees to advance voltage security monitoring.Applications resulting from integrating phasor datawith SCADA/EMS data are treated in detail; fromenhancing the quality of existing estimators torevolutionizing it to phasor-based state estimation.Graph theoretic algorithms and the new concept ofdepth of unobservability are introduced forsystematic placement of PMUs around the network. These techniques are extended to solve the problem ofphased deployment of PMUs considering limitations incommunication links. The topics should help shedsome light in this exciting measurement technology,and should be useful to professionals and studentsalike who want to advance their understanding ofsynchronized phasor measurements.
