摘　　要：综述了国内外对连锁故障机理和连锁故障模型的研究现状,分析了高压直流输电系统接入传统电网所带来的影响,讨论了已有连锁故障机理和模型在交直流电网的适用性以及存在的问题。在此基础上,从深入探索交直流电网连锁故障机理、建立更符合交直流电网实际的连锁故障模型、搭建精确高效的连锁故障仿真平台和制定交直流电网连锁故障预防策略4个方面展望了未来研究方向。This paper presents an overview of the research status of cascading failure mechanism and model at home and abroad, analyzes the impacts of DC Power Transmission System connection to conventional power grid, and discusses the adaptability and existing problems of the current cascading failure mechanism and model when applied to AC/DC power grid. Then the vista of the future research is made from the four perspectives ： exploring into AC/DC power grid cascading failure mechanism, establishing the cascading failure model more adaptable to the actual AC/DC power grid, building up the accurate and efficient simulation platform for cascading failures, and formulating AC/DC power system cascading failure prevention strategies.
