摘　　要：为了避免在故障计算中重复计算全网阻抗矩阵元素,介绍了一种规范的计算机算法,对算法的核心部分,即故障描述矩阵Yf进行了分析。首先论述了数学上Yf的列写过程,然后根据推导的2类典型故障,总结得到电网理论上出现N处错误时Yf的实用化公式并给出了电路上的解释,并在工程项目中得到了应用。In order to avoid calculating the impedance matrix elements of the whole network repeatedly, a canonical computer algorithm suiting for various complicated fault is introduced in this paper. The form of the matrix in mathematics, a core part in the algorithm, is analyzed. A general format of the by deducing two types of typical fault is presented and the explanation in real fault circuits is given.
