【摘要】 电力网络连锁故障是由某一个故障引发的一系列故障过程,其后果是造成大规模的停电事故和许多关键元件的开断。由于电网故障模式较多,故障参数(包括各种连续参数和离散变量)形式各异,因此连锁故障模式的搜索和后果分析十分困难。近年来,研究人员建立了多种方法和模型,如模式搜索法、模型分析法等。综述了电力网络连锁故障领域的一些研究成果,并指出应从提高故障模式搜索速度、计及稳定性问题、采用复杂网络理论进行模型分析和连锁故障的预防控制、校正控制和紧急控制等方面进行深入研究。更多还原

【Abstract】 Cascading failure is a series of successive failures caused by one failure,which may result in large-scale blackout and unexpected trips of many critical components.Due to multiple fai-lure modes and different failure parameters,continuous and discrete,the search of cascading failure modes and their effect analysis become very difficult.In recent years,many methods and mo-dels have been put forward to study the mechanism and behaviors of cascading failures,such as mode search method,model analysis method and so on.Some are reviewed,and it is pointed out that the further research should be done in the improvement of failure mode search speed,consideration of stability,application of complex network theory,preventive control,corrective control and emer-gency control.更多还原
