摘　　要：提出电力系统故障分析的相网络计算法。首先计算出故障点的等值阻抗，然后推导出各种不同名相故障的相网络，采用此相网络，通过简单的运算变换，即能得到故障的计算结果。该法与传统序网络法相比，显得更为优越。This paper proposes the phase network calculation method- The equivalent impedance of the fault node is computed, then the phase networks of various faults on different phases are deduced- By using the phase network. The calculated results can be obtained through the easy computation and transformation. This new method is superior to the traditional method of the sequence network.
