摘　　要：提出一种考虑统一潮流控制器(unified power flow controller,UPFC)系统级和换流器级控制策略的线路功率调节能力计算方法,实现了电网正常运行和N-1情况下UPFC对线路潮流有效控制范围的计算。介绍了UPFC工程的控制策略,在考虑并联侧定电压控制和定无功控制特性的基础上实现潮流分析,并以南京西环网UPFC为例,基于江苏电网的实时运行数据对UPFC的实际潮流控制范围进行计算,为电网调度运行提供参考。An algorithm of calculating the capacity of UPFC based on both system and converter strategy is proposed. The comparison of effect in normal and N - 1 situation is researched. Control strategy of Nanjing UPFC project is introduced, while power flow is calculated based on UPFC parameters, voltage and reactive power control modes. Control range of UPFC is computed by PSS/E and Python with the real-time data of Jiangsu Power Grid. The result can improve the safety and reliability of Jiangsu Power Grid.
