摘要
工厂配电系统中以感性负载—电动机为主,消耗无功功率较大,系统功率因数较低,对电网不利,需要无功功率补偿设备,介绍了以负荷统计方式来计算配电系统中无功功率补偿容量的粗略计算方法及无功补偿设备的选用。
The loads factory-running distribution system is mainly inductive （motor）, which consumes more reactive power, has lower system power factor and has negative effects on power grids. Reactive power compensation equipment is needed in the distribution system. The paper introduces a rough calculation method of the capacity of reactive power compensation in the distribution system by means of a load statistical approach and how to select reactive power compensation equipment.
