电力系统连锁故障风险分析

Analysis on Fault Chain Risk of Power System

在电力系统的生产运营过程中,由于客观因素或是主观人为因素(工作人员误操作),常常会出现各种故障。严重的电力系统连锁故障会导致整个电力系统停止运行,造成大面积的停电,因此对电力系统进行连锁的故障分析是十分必要的。文章在此背景下,分析了连锁故障的产生原因和主要影响因素;介绍了评估连锁故障的风险分析的方法和原理;最后介绍了在电力系统中风险评估方法的具体应用。

In the production process of the electric power system,some faults will appear because of the objective factors or subjective artificial factors. Serious power system faults chain will lead to stop running of the whole power system, cause widespread blackouts, so the power system fault analysis of chain is very necessary. In this context, the fault reasons for the chain and the main influence factors are failure are introduced. At power system is introduced. analyzed. Then the risk analysis method and principle of cascading last, the specific application of the risk assessment method in the power system is introduced.
