一种规范化的计算机故障分析计算方法

A canonical method for fault analysis

提出了一种规范化的计算机故障分析计算方法。该方法不用进行纵向故障的支路破口，也不用进行线路中间故障的新增节点等处理，保持故障前网络方程不变，任何多重复杂故障，包括不对称短路、跳闸、重合闸都在一个较小的附加故障电路上进行，特别适合于计算机进行复杂故障计算。

canonical method for fault analysis is presented in this paper. Neither branchcutting to deal with series faults caused by circuit breaker operation nor bus creation to process intermediate line faults is needed in this method. The pre-fault network keeps unchanged in the whole fault calculation. A local modification is carried out to simulate asymmetrical short circuit, circuit opening and reclosure, which makes the method more suitablefor computer analysis. A calulation example is also given.
