摘要
随着城市轨道交通的迅速发展,地铁供电系统动力照明负荷、变频设备的使用持续增多,导致无功功率和谐波问题日益严重。提出一种利用0.4 kV侧设置的有源滤波装置协同电抗器进行35 kV系统无功补偿的新方法。在地铁供电系统无功补偿领域内,首次将两者结合,探索出既节省成本,又能满足地铁供电系统功率因数要求的新无功补偿方式。
With the rapid development of urban rail transit, power and lighting load as well as inverter equip- ment of metro power supply system are continually increasing. The problem of reactive power and harmonicbecoming increasingly serious. A new method of 35 kV system reactive power compensation by using collaboration of 0.4 kV side active filter and reactance is proposed. It is the first time to combination of both inthe reactive power compen- sation fieldof Metro Power system. Explored anew way ofreactive power compensation, which can not only saving- cost, but also meeting the the power factor requirements of metro power supply system.
