大电网防连锁过载跳闸控制策略的分析

Analysis of Control Strategy of Anti Chain Overload Trip in Large Power Grid

近几年,大规模电网连锁出现故障的情况不断增多。因此,结合各地电网运行的实践,论述大电网的特征和连锁跳闸出现的风险因素,并针对大电网运行中出现的风险特征,提出相应的控制对策,以供参考。

In recent years, large scale power grid cascading failures have been increasing. Based on the practice of power grid operation, this paper discusses the risk factors of chain tripping and the actual characteristics of large power grid. According to the risk characteristics of large power grid operation, the corresponding control strategies are put forward for reference.
