摘　　要：配电网无功优化是节能降损的一项重要措施,而做好无功补偿设备的优化配置是配电网无功优化最重要的环节。为此,从实用角度出发,以减少配电网有功损耗为目标函数,采用惩罚函数的方法对就地无功补偿装置的安装数量和节点电压质量加以约束,在此基础上采用遗传算法确定配电网就地无功补偿电容器的最佳安装位置和补偿容量。通过对配电网IEEE36节点和某城区实际配电网系统的验算,表明了该算法的可行性和有效性。The reactive power optimization in distribution system has become an important role of reducing energy loss,and optimal placement of the reactive compensation equipment is the most important point.This paper uses the index of maximum reduction of active power losses as the objective function from the practicality point of view.The total number of reactive compensation devices and the voltage quality of nodes are restricted by using a penalty function.On this basis,a genetic algorithm is used to determine the optimal installation location and capacity of the reactive compensation capacitor.An IEEE 36-node distribution network and an example show that the proposed method is feasible and effective.
