摘　　要：建立了以系统有功网损为最小的目标函数、电网潮流方程为约束条件、发电机升压变压器电抗为控制变量的高压侧电压控制模型。采用路径跟踪内点法进行优化,在此基础上对IEEE-30节点系统不同的运行状态进行计算。结果表明,高压侧电压控制(HSVC)优化方法可以有效地降低系统网损。Active power loss as minimum objective function,network power flow equation as the constraint and reactance of generator＇s step-up transformer as controlled variable,high-side voltage control model is established.This paper adopts path-following interior-point algorithm to optimize control model and on the basis of which calculates different operation conditions of IEEE-30 nodal system.Calculation result indicates that optimization of high-side voltage control（HSVC） effectively reduces network loss.
