摘要: The Frequency Monitoring Network (FNET) takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at the 120V distribution level with data rate of 10 sps. Various advanced situational awareness tools have been developed using FNET measurements, including disturbance alert, event location triangulation, oscillation detection, etc. Since late 2010 FDR deployment has gradually covered some worldwide areas, e.g. Europe, China. In this paper, firstly, observability power system disturbances by areas is examined and compared North American grid, taking European Power Grid as example. Secondly, paper investigates dynamics during several major Eastern Interconnection Western captured 2011. Important parameters (e.g. frequency, phasor angle, voltage magnitude) taken FDRs are analyzed.
