摘　　要：基于对称分量坐标、用附加节点注入功率法,建立了统一潮流控制器(UPFC)在给定控制方式下计算三相潮流的三序解耦模型;三序解耦潮流采用正序约束条件,UPFC正序模型按附加节点注入功率计算,负序、零序模型按附加节点注入电流计算;结合牛顿—拉夫逊法编制了该潮流计算程序。因潮流可按正序、负序、零序分别求解,在保证求解精度的前提下提高了求解效率。Based on the symmetrical component coordinate system, using the method of additional nodal injection, this paper presents a decoupling model of UPFC for the three phases power flow calculation. Owing the positive bus specifications, the positive sequence model of UPFC adopts the algorithm of additional nodal injection power, while negative and zero sequence adopt the algorithm of additional nodal injection current. Then a three-phase flow program is brought up by the incorporation of Newton-Raphson algorithm. With this program, power flow study can be undertaken in positive-, negative- and zero-sequence reference frames separately, thus the computation efficiency can be apparently enhanced with acceptable precision.
