在 10kV线路中,无功补偿设备配置不合理容易导致无功流通路径过长,从而增加系统网损,降低供电电压质量.为此提出一种基于改进遗传算法的无功补偿设备最优配置方法.该方法将年线损率最小作为目标函数,将线路电压合格作为约束条件,采用实编码遗传算法求解无功补偿设备的最优安装位置和容量.依照北京某地区配电网构架和实际运行数据搭建仿真模型.仿真结果验证该方法能有效降低系统的投资成本和运行损耗,提高线路供电质量.
Modified-genetic-algorithm-based Optimal Configuration Strategy for Reactive Compensation Devices of 10 kV Lines
Inappropriate configuration of reactive compensation devices in 10 kV lines usually leads to excessive distance of reactive current flow,increased network loss and reduced supply voltage quality.The present work studied a modified-ge-netic-algorithm-based method to optimally configure reactive compensation devices.The method works through saliently the calculation of optimal installation locations and capacities via a real-coded genetic algorithm,in which the objective and the constraint are minimum annual line loss rate and qualified line voltage,respectively.Simulation on a case model built based on structure and actual operation data of a regional distribution network in Beijing verified tentatively the effective-ness of the proposed method in configuring reactive compensation,which is manifested by reduced system investment and operation loss,and improved quality of electric supply.
