摘要
研究连锁故障对防御大电网停电事故具有重要意义。针对连锁故障的系统建模、风险评估、监测预警及脆弱性分析等相关方向的研究难点与关键技术,总结了目前已取得的国内外研究成果。首先剖析了连锁故障模型的建立方式,对连锁故障风险评估方法进行了分类梳理,综述了连锁故障在电网安全分析方面的应用情况,最后通过探讨后续亟需关注的问题展望了连锁故障研究的发展趋势,以期为新环境下大电网安全防御策略提供科学依据。
Cascading failure research has great significance for blackout defense .Aiming at the difficulties and key technologies of system modeling , risk assessment , forewarning and vulnerability analysis about cascading failures , the research results at home and abroad are summarized .Firstly, the models of casca-ding failures are comparatively discussed in detail .Then risk assessment methods are categorized and il-lustrated .And the application situation related to gird security analysis of cascading failure is explained . Finally , by probing some challenges in need of urgent attention , the development tendency of cascading failure research is forecasted , with expectation to provide a scientific basis for grid security defense strate-gy under the new environment .
