摘　　要：随着电网规模和交直流混合系统建设工作的快速推进,UPFC应用研究又成为热点之一。针对UPFC的不同控制需要,开展了不同控制策略下UPFC控制特性分析及其对电网潮流的影响研究。首先,本文针对不同的UPFC控制策略,建立了相应的常规潮流方程的修改模型,实现了直接采用常规潮流程序计算含UPFC的电网潮流的方法;然后,通过含UPFC电网的潮流分析,剖析了UPFC的稳态调控性能及其对系统潮流的影响能力;最后通过典型数据验证了本文模型和方法的有效性,对实际电网中应用UPFC具有一定的借鉴与指导意义。With the increasing scale of power grid and construction of AC and DC hybrid system,the application of UPFC has become one of the key issues.In this paper,the control characteristics of UPFC under different control strategies and its influence on power flow are studied according to different control needs.Firstly,modified models of conventional power flow equations are built according to different UPFC control strategies,in which conventional power flow calculation program is used to calculate power flow with UPFC directly.Then,through analyzing the power flow with UPFC,the steady-state control performance of UPFC and its influence on power flow are analyzed.In the end,the validity of proposed model and the method are verified by classical data,which will have a certain reference and guiding significance for the application of UPFC in actual network.
