| 摘 要： | 提出了一种既适用于简单故障，又适用于复杂故障的计算机通用模型．该算法不需要考虑故障端口是横向或是纵向，也不需要考虑序网的串并联问题，而是将故障边界条件导出为相应的修正导纳矩阵，叠加在原三序网络导纳矩阵中，同时解决了变压器变比和相位位移问题．模型简单通用性强，适合于大规模电网故障计算．

| Abstract: | A new universal method for fault computation in electric power system is presented. The method is suitable to all kinds of simple faults and complicated faults. This method need not consider fault port is horizontal or vertical, and the connection of sequence networks is serial or parallel; a modified admittance matrix that is derived out by fault conditions superimposes prefault sequence networks. The method also solves the problem of transformer ratio and transformer phase shifts. The method is simple, universal, and suitable to the large scale power grid fault computation. |
