随着国家经济的发展和人民生活水平的提高,大量的居住楼盘、高档商场、宾馆、办公楼等民用建筑在城市中拔地而起,使城市用电量快速增长.但是,在这些民用建筑场所内使用的多为单相电感性负荷,因其自身功率因数较低,在电网中滞后无功功率的比重较大.为保证降低电网中的无功功率,提高功率因数,保证有功功率的充分利用,提高系统的供电效率和电压质量,减少线路损耗,降低配电线路的成本,节约电能,通常在低压供配电系统中装设电容器无功补偿装置.
无功补偿,就其概念而言早为人所知,它就是借助于无功补偿设备提供必要的无功功率,以提高系统的功率因数,降低能耗,改善电网电压质量.无功补偿的合理配置原则,从电力网无功功率消耗的基本状况可以看出,各级网络和输配电设备都要消耗一定数量的无功功率,尤以低压配电网所占比重最大.为了最大限度地减少无功功率的传输损耗,提高输配电设备的效率,无功补偿设备的配置,应按照“分级补偿,就地平衡”的原则,合理布局.

With the national economic development and improvement of living standards,a large number of residential properties for sale,high-end stores,hotels,office buildings going up in cities such as civil construction,rapid growth of urban consumption.However,in these civil establishments mostly used in single-phase inductive load,because of its low power factor,lag in reactive power grid in a larger proportion.To ensure the reduction in reactive power grid,improve power factor,active power to ensure the full utilization efficiency and improve the system power supply voltage quality,reduce line losses,reduce the cost of distribution lines,save energy,
Usually in the low-voltage power supply system installed capacitor reactive power compensation equipment.
Reactive power compensation,in terms of its concept as early as known,it is by means of reactive power compensation device to provide the necessary reactive power to improve system power factor,reduce energy consumption,improving the power grid voltage quality.Reasonable allocation of reactive power compensation principle,the reactive power from the power consumption of network fundamentals can be seen at all levels of network and transmission and distribution equipment must consume a certain amount of reactive power,especially in the largest proportion of low-voltage distribution network.In order to minimize reactive power transmission losses,improve the efficiency of power transmission and distribution equipment,reactive compensation equipment configuration,should be in accordance with the "classification of compensation,local balance" principle,reasonable layout
