摘要
Abstract
In recent years, the large-scale blackouts in power system have occurred occasionally , and the cascading failures become an important cause leading to it .So it is of important guiding significance for the prevention of large-scale blackouts to quickly and accurately forecast the cascading failure possible paths .As for the overload oriented de-velopment model of cascading failures featured by relevance between adjacent failure links , relevance indicator is de-fined , and a method of fast forecasting for power system cascading failures based on failure path tree is proposed .The method uses fuzzy C-means to classify the relevance indicator , selecting the branches with the highest value of rele-vance indicator as the next failure branch .It effectively reduces the computational load , and overcomes the shortcom-ings of existing methods .Finally, the simulation results of IEEE 39 nodes prove the rapidity and correctness of the proposed forecasting method .关键词
