自适应重合闸的应用与评价

Application and Evaluation of Adaptive Reclosing

自动重合闸的应用是建立在绝大多数线路故障为瞬时性的基础上，在出现冰冻等自然灾害的情况下，其盲目重合闸的弊端会突显出来，而自适应重合闸通过故障性质的判别可以弥补这一缺陷。自适应重合闸的评价方法应增加正确不重合率指标，但在当前在线的故障性质判别方法并不成熟的情况下，可沿用常规重合闸的评价方法，但不应据此错误理解自适应重合闸所产生的效益。探讨了自适应重合闸的可控性以及试运行中应注意的事项。

Auto -reclosing is built on the line fault which is mainly instantaneous. In the natural disasters such as freeze the permanent fault accounts for the most, but the auto - reclosing can make up for the defect through discriminating the fault nature. Adaptive reclosing evaluation method should increase the right un - adaptive rate index, but in the current online fault evaluating method which is not mature, the conventional evaluating method can continue to be used. The paper discusses the items which should be paid attention to the controllability of adaptive reclosing and its operating.
