摘　　要：统一潮流控制器(UPFC)为电力系统无功优化提供了新的控制手段。针对实际工程中的新型拓扑,建立UPFC的多端注入功率模型和功率方程;基于将无功设备动作次数的约束还原成调节代价的思想,提出一种只含连续变量的基于原-对偶内点法的两阶段无功优化算法。南京西环网等值系统的算例测试结果表明,所提算法具有较高的计算精度和求解效率,可以有效减少无功设备的动作次数。UPFC(Unified Power Flow Controller)provides a novel control means for reactive power optimization of power system.Aiming at the novel topology in practical engineering,a multi-terminal injection power model and power equations of UPFC are established.Based on the idea that transferring the action times constraint of reactive power devices into adjustment cost,a primal-dual interior point method based two-stage reactive power optimization algorithm is proposed,which only contains continuous variables.The case test results of equivalent system of Western Nanjing Ring Network show that the proposed algorithm has high calculation accuracy and solving efficiency,and it can effectively reduce the action times of reactive power devices.
