摘　　要：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。Microcomputer based adaptive reclosure can process reIated digital and statevalues directly. Through forecast and assessment of the system state and application ofcorresponded adaptive measures, the influence of the reclosure on the system may belimited to minimal range. This paper describes the adaptive state estimate models andforecast algorithm of the adathive reclosure and derives their mathematical expressions.
