Application Research Based on PMU in Power System

With the gradual development of the GPS-based Phasor Measurement Units(PMU),they probably will be the one of main trend in the future because the model of SE based on PMU has obvious advantages over the centralized control for the large-scale interconnected system.The phasor measurement technology based on GPS was introduced briefly.The function of phasor measurement technology in the state estimation was also focused and studied,and how to add these phasor measurements into state estimation was introduced.
