含统一潮流控制器的电力系统新型潮流算法

A NEW TECHNIQUE FOR POWER FLOW CALCULATION OF POWER SYSTEM WITH UPFC

本文通过对统一潮流控制器 ( UPFC)在电力系统中控制原理的分析 ,提出了一种计及 UPFC的新型潮流算法。在原有潮流计算牛顿 -拉夫逊法的基础上 ,将 UPFC对系统的影响转移到对潮流方程的修正中去 ,选取新的状态变量 ,为电力系统稳态潮流控制打下了基础 。

This Paper Proposes an improved, systematic and efficient load flow algorithm for UPFC embedded power system. The selection of new state variables and the solution of conventional power flow equations together with UPFC device constraint equations are described in this paper. Numerical examples are given to indicate that the improved UPFC load flow approach is reliable and efficient.
