基于模糊理论的计及元件危险性因子的N-2故障快速筛选法
N-2 Fault Set Rapid Screening Method Based on Fuzzy Theory and Risk Factor
摘要
Abstract
Power system is developing in direction of large capacity,extra-high voltage and long distance.With power grid expansion,consequences of power grid fault are increasingly serious.Power grid reliability attracts wide attention.In engineering practice,N-2 test is used to evaluate power grid reliability.But N-2 test process is rather complicated.In this paper,an N-2 fault set rapid screening method based on risk factor and fuzzy theory is proposed.Risk factor and N-2 ordering index are defined.By adjusting parameters,this method can reduce N-2 fault set number needed for calculation,greatly improving computation efficiency.This method is applied to N-2 test of actual engineering applications in Hubei power grid and IEEE 39-bus system.Results are compared with those of another N-2 test method,demonstrating validity of the proposed method.关键词
