摘要(Abstract)：

DPFC（分布式潮流控制器）可以改善电网潮流分布，解决输电断面超限问题。根据DPFC的拓扑结构和运行原理，依托世界首个220 kV DPFC示范工程，搭建了DPFC的仿真模型。分别考虑DPFC集中安装于变电站内和分散安装于输电线路两种情况，仿真计算了输电线路发生短路故障时DPFC关键节点的过电压和过电流水平，并分析了故障发生位置对DPFC过电压和过电流水平的影响。计算结果可为实际工程中DPFC的绝缘配合提供参考。
Distributed power flow controller(DPFC) can improve power flow distribution in the power grid and solve the problem of power flow section excess. Based on the topology structure and operation principle of DPFC and with the backing of the world's first 220 kV DPFC demonstration project, a distributed power flow control simulation model is established. The cases of distributed power flow controllers centrally installed in substations and dispersedly installed in transmission lines are considered, respectively. The overvoltage and overcurrent levels of DPFC key nodes in the case of short-circuit faults on the transmission lines are simulated. Moreover, it is analyzed how fault location influences the DPFC′s overvoltage and overcurrent. The calculation results in this paper can provide a reference for DPFC insulation coordination in engineering practice.
