Analysis of wide-area frequency measurement of bulk power systems
Field-measured frequency data from a nationwide frequency monitoring network (FNET) are examined in this paper. Wavelet-based denoising signal processing technique is applied to filter out spikes and noises from measured frequency data. System's frequency statistics of three major U.S. power grids are investigated. Comparison between phasor measurement unit (PMU) and FNET data illustrates the close tracking between the two. Several generator trip events in the Eastern Interconnection System and the Western Electricity Coordinating Council system are recorded and the frequency patterns are analyzed. Sample results are shown for a 13 month period of time. In addition to transient states' observation, the quasi-steady-state, such as oscillation, can also be observed by FNET
