| 摘 要： | 大区互联电网中稳定性事故最严重的仍首推稳定性破坏(失步振荡),处理不当便会发生大面积停电。解决失步振荡问题要正确选择失步解列的判据,做好装置间的协调配合,选择好解列点和解列时刻。该文通过对六种电力系统失步解列判据的分析,阐述了目前解列装置中这些算法的优势和不足,指出基于WAMS装置采集的实时数据的解列判据潜在优势和基于全网考虑装置间协调配合的可能性。最后给出了不同安装点解列装置动作的配合方法及解列点、最佳解列时刻的选择方法。

| Abstract: | Out-of-step protection is the worst situation to prevent a power system from collapse in large-sized connection electrified wire netting.If no methods being adopted to deal with it,the power system will blackout.It needs the right criteria for detecting the synchronization loss,doing well with the coordination methods,and selecting the situation and the time to trip the generators.This paper outlines six criteria for detecting the synchronization loss and presents the advantages and disadvantages respectively.The result indicates wide area measure system based criteria for detecting the synchronization loss is the best one.On the experiment,the paper puts forward the method to choose the situation and the time to trip the generators. |
