摘要
介绍了地铁供电系统的主要构成,并建立了等效负荷模型;重点分析了地铁供电系统负荷的无功特性及其对电网的主要影响,并设计出相应的补偿方案;最后以某城市地铁工程的无功补偿为案例对该补偿方案进行验证,证实其效果良好。
It introduces the main structure of metro power supply system and builds up its equivalent loads model.With the typical analysis of reactive power compensation characteristics of the loads for metro power supply system and its main effects to the grid,a compensation strategy of reactive power is proposed accordingly.The strategy is verified by taking the reactive power compensation of an urban metro project as an example and the result is well.
