WAMS-Based Dispatcher Strategy Against Low Frequency Oscillations in China Southern Power Grid
摘要
Abstract
In China Southern Power Grid, the inter-area low damping oscillations have been eliminated effectively so far, but there are local and generator-induced low frequency oscillations yet. The dispatcher strategy for low frequency oscillations is discussed in this paper, including the early warning and prevention before oscillations and the emergency control of oscillations. The modal parameter identification method using ambient data is used for early warning and prevention of oscillations. The method avoids the dependence on the models and parameters, and with redundant data it can improve the credibility of the results and the damping ratios of both inter-area modes and local modes so to realize the early warning and prevention of critical modes. The oscillation source location method based on oscillation energy is adopted to find the cause of the oscillation, and to locate the oscillation source quickly and reliably, and to give dispatchers the instructions to damp the oscillation. The proposed dispatcher strategy is demonstrated in a real oscillation incident and its validity is verified.关键词
