摘　　要：为建立与电力系统分析综合程序(PSASP)相适应的统一潮流控制器(UPFC)潮流控制模型,提出一种解耦控制方法。串联侧分别采用串联注入电压的q轴和d轴分量控制线路传输的有功功率和无功功率,并联侧基于瞬时功率理论,采用并联侧电流的q轴分量控制UPFC并联接入点母线电压,通过改变UPFC与网络接口节点的注入电流实现UPFC的潮流控制目标。在国内某500 kV电网上进行了潮流控制计算,计算结果表明,所建立的模型正确、可行,完全可用于含UPFC的实际电网的工程研究和分析。A decoupling UPFC power flow control model is established in this paper, which is adaptive with Power System Analysis Software Package （PSASP）. On the series side of UPFC, the q-axis and d-axis components of the series-injected voltage are used to control the active and reactive power of the transmission line, respectively. On the shunt side of UPFC, the q-axis component of the [IPFC shunt eurrent is used to cuntrol the bus voltage of the UPFC-conneeted point based on the instantaneous power theory. The UPFC power flow cnntrol goals are achieved by regulating the injection current of the buses where UPFC is embedded into the system. The established power flow control model is applied to a 500 kV power grid and the calculation results verify that the model is accurate and feasible and can be used for engineering research and analysis of practical power grids with UPFC.
