树状配电线路并联电容器无功优化规划

为解决含分支树状配电线路无功补偿问题,提出了在树状配电线路安装多台固定容量电容器的无功优化规划方法。该方法以净节约金额最大为目标函数,采用等效负荷法将树状配电线路转化为多个梳状配电线路,分别对各个等效线路进行优化规划,将目标函数值最大者对应的方案确定为最优规划方案。实例分析和规划结果验证了该方法的正确性和可行性。

Optimal Planning of Shunt Capacitors Based Reactive Power Compensation for Arborescent Distribution Feeders

To solve the reactive power compensation problem of rural distribution network containing arborescent distribution feeders, an optimal planning algorithm by which many capacitors with fixed capacity are installed in branched radial distribution feeders is proposed. The benefit of loss reduction by shunt capacitors is used as the index. By means of equivalent load method a branched distribution feeder is transformed into many comb-shaped distribution feeders and the optimal planning for each equivalent feeder is performed separately, then the planning with maximum value of objective function is determined as the optimal one. Case study analysis and planning results show that the proposed method is corrective and feasible.
