摘　　要：基于多端口网络理论,提出了同塔4回线发生复杂故障时电气量的计算和暂态仿真分析方法。将受故障影响的同塔4回线单独取出研究,保持故障前网络方程不变,避免了序坐标下复杂的序网连接,已用于PSS/E仿真程序中。该方法在华东电网的成功应用证明了其有效性和实用性。Based on the multiple-terminal network theory, this paper presents a method for electric parameters calculation and transient simulation analysis when a complicated fault occurs in common tower quadruple circuits. In this method, the quadruple circuits are retrieved while keeping the rest of pre-fault network unchanged. The complicated connection of the sequence network is therefore avoided. It has been applied in a PSS/E simulation program. The method is validated through its successful application in the 500 kV common tower quadruple circuits project of the East China Grid.
