摘要
电力系统中存在着大量的感性负荷,电路中总电流滞后电压一定相位角,引起功率因数偏低,存在设备容量得不到充分的利用,在设备容量选择时偏大,线路中计算电流偏大的现状.为解决上述问题,对电路中并联电容器无功补偿进行研究,主要分析影响功率因数的主要因素、无功补偿的原理,通过理论计算以及利用实例在Multisim中仿真的方法,对并联电容器无功补偿的原理给以充分说明,并给出电容器容量计算的方法,最终通过实例仿真加以验证.
Abstract
There is a large amount of inductive load in the power system,and the total current lag voltage in the circuit has a certain phase angle,resulting in low power factor.There is the current situation that the equipment capacity can not be fully utilized,the equipment capacity selection is large,and the calculation of the current in the line is large.In order to solve the above problems,this paper researches the reactive power compensation of shunt capacitor in the electric circuit,mainly from the main factors affecting the power factor,the principle of reactive power compensation,through theoretical calculation and the method of using examples simulation in Multisim,fully explains the principle of reactive power compensation of shunt capacitor is,and gives the method of capacitor capacity calculation.Finally,it is verified by an example simulation.
