自适应重合闸基于微机保护基础，因此能直接处理相关的数字及开入量，它通过对系统状态的预测判别而采用相应的自适应对策，可以最大限度地使重合问对系统的影响变小。文章主要论述了自适应重合闸中自适应状态估计模型及预测算法，从理论角度给出了它们的数学表达式。
Adaptive reclosing is based on the basis of microcomputer protection, so it can directly deal with the relevant figures and the amount of opening. By adaptively adjusting the state of the system, adaptive reclosing can minimize the influence of coincidence on the system . This paper mainly discusses adaptive state estimation model and prediction algorithm in adaptive reclosing, and gives their mathematical expressions from the theoretical point of view.
