摘　　要：基于附加节点注入功率法,建立了统一潮流控制器(UPFC)在给定控制方式下的三相附加节点注入功率模型。在研究了UPFC三相附加节点注入功率模型的基础上,运用三相解耦-补偿理论,对三相系统进行潮流计算。通过网络分析,说明了UPFC元件在改善系统的三相不平衡的作用。经算例仿真,验证了建立的UPFC三相潮流模型及运用算法的合理性和有效性。Based on the additional node injection power method,this paper establishes the three-phase additional node injection power model of unified power flow controller（UPFC） under the given control mode and conducts power flow calculation of three-phase system by three-phase decoupling-compensation theory on the basis of the study of three-phase additional injection power model with UPFC.Through the network analysis,it is proved that UPFC component is effective to improve the three-phase unbalance.Finally,example simulation verifies the rationality and effectiveness of the three-phase power flow model and algorithm with UPFC.
