| 摘 要： | 故障模拟是电力系统动态仿真的重要组成部分。电力系统全过程动态仿真软件的故障模型采用故障支路导纲阵模拟各种对称和不对称复故障，利用导纳阵收缩技术处理多重故障和随机发生的故障。该方法的特点是可以对一条支路发生任意重故障进行处理，而不需要增加支路或节点，从而提高软件的计算效率和使用的方便性。

| Abstract: | Fault simulation is one of the main constituents of power system dynamic simulation. In power system full dynamic simulation software the admittance matrixes of faulty branches are adopted in the fault models to simulate arbitrary symmetrical and unsymmetrical faults, by use of contraction technique for admittance matrix the multi-faults and the randomly occurred faults can be processed. The feature of this method is that the arbitrary multi-fault occurred in a branch can be simulated without any additional branches or buses to be added, thereby, the calculation efficiency and the expedience of usage are improved. |
