摘　　要：区分瞬时性和永久性故障为目的的自适应重合闸,能减少故障对电能的损失,增强电网的稳定性。虽然单相自适应重合闸研究已较成熟,但同杆双回线上自适应重合闸和三相自适应重合闸的研究仍存在很多未解决的问题。结合各种情况下自适应重合闸实现原理,对目前自适应重合闸研究现状作了阐述,介绍了自适应重合闸顺序。同时,针对目前的研究现状,提出各研究方法或理论的不足,并结合近年来的研究和最新进展,展望了自适应重合闸的发展前景。The self-adaptive reclosure,which is aimed to distinguish the transient fault and the permanent fault,can reduce the power loss caused by faults and enhance the stability of power system.Although the single-phased adaptive reclosure technology has been mature,the research of single-phase adaptive reclosure and three-phase adaptive reclosure on double circuit lines on the same tower still exists many unsolved problems.The current research of self-adaptive reclosure is introduced based on its principles in various cases,and the reclose sequence is also presented.In addition,for the current research situation,the drawbacks of each theory or method are discussed.Finally,the paper gives the development prospects of self-adaptive reclosure combined with recent research and latest progress.
