摘　　要：统一潮流控制器(UPFC)作为一种经济、有效的潮流调节手段,在交流电网中的应用日益增多,未来将发挥不可或缺的重要作用。在电网发生故障时,UPFC系统快速、可靠的自身切除能力将直接影响到电网的安全运行。文章介绍了南京UPFC工程的接线结构及接入方式,详细阐述UPFC设备的故障处理策略,针对一次实际母联开关接地故障后UPFC的动作情况进行详细分析,验证了设备故障处理策略的合理性和正确性。As an economic and effective method for power flow regulation,the Unified Power Flow Controller（UPFC）has been increasingly used in the AC power grid. When the power failure happens,the fast and reliable self-cutting capacity of UPFC will directly affect the safe operation of the grid. The structure and main connection diagram of Nanjing UPFC project are introduced,the fault handling strategies are described in detail,and all actions of UPFC after an actual ground fault are analyzed at last. The result verifies the rationality and correctness of the fault handling strategies for UPFC.
