摘　　要：基于低压配电系统的单母线分段回路,各段母线需分别集中配置一套由电容器组成的无功补偿装置,以提高功率因数水平。通过对单母线分段回路中并联电容器的设计分析,指出常规的电容器容量选择存在弊端。为此提出了两种优化解决方案,在满足单母线分段回路中各种工况下无功需求的前提下,能较大程度地降低电容器的配置容量,提高利用率,有显著的经济效益。In the single-busbar segmented distribution circuit of the low-voltage distribution system,each section of the bus needs to be centrally equipped with a set of reactive power compensation devices composed of capacitors to improve the power factor level.Through the design analysis of shunt capacitors in single-busbar segmented distribution circuits,it is pointed out that there are disadvantages in conventional capacitor capacity selection.Therefore,two optimization solutions are proposed,which can greatly reduce the configuration capacity of capacitors,improve the utilization rate,and have significant economic benefits under the premise of meeting the reactive power requirements under various working conditions in the single-busbar segmented circuit.
