摘　　要：文章建立了以有功网损最小为目标函数的无功优化数学模型,利用非线性规划最优潮流算法进行了优化计算。并且研究了无功补偿装置采用不同的动作顺序对有功网损最小化的控制效果,提出了以有功网损控制效力为灵敏度指标的无功优化控制策略。Ward&Hale 6节点系统和IEEE-14节点系统验证了算法和控制策略的有效性。This paper establishes a mathematic model of var optimization,regarding the minimization of active power losses as objective function , and then uses non- linear programming algorithm to complete the var optimization. It also studys the impact of var compensation equipments on the effect of active power losses minimized, adopting the different order of control actions. According to these analysis, the paper provides a control strategy based on the sensitivity factor of active power losses control effectiveness. By testing the Ward ＆ Hale 6 system and IEEE- 14 standard system, the results verify the effectiveness of the proposed algorithm and control strategy.
