摘　　要：利用等效功率注入方法 ,提出一种含 UPFC的灵活交流输电潮流计算方法。该方法将 UPFC对潮流的控制作用转移到所在线路的两个节点上 ,联立潮流控制目标 ,修正雅可比矩阵 ,再运用传统的潮流计算方法——牛顿—拉夫逊法进行求解。Ward &Hale6节点等多个仿真算例显示了UPFC在稳态情况下 ,能够独立、快速控制线路中的有功、无功潮流 ,验证了该算法具有较好的可靠性和有效性。A method to compute the power flow of flexible AC transmission system with UPFC using the equivalent powerInjection is proposed. It transfers the control of UPFC towards the power flow to the two nodes connecting the UPFC firstly,then joins power flow control target of the lines associated with UPFC and revises the Jacobian matrix. finally solves theequations using the Newton--Raphson method. Ward & Hale 6 nodes simulation and other examples show the UPFC cancontrol the active and reactive power in the lines in the steady state, and the method is effective and reliable.This project is supported by National Key Basic Research Special Fund of China (No. G1998020308).
