摘　　要：无功功率补偿是电力系统中的一项重要工程。通过设计无功自动控制器来实现并联电容器组的投切,保证功率因数在给定的合格范围内变动,完成无功功率的补偿。设计以CS5460A为核心芯片,从电网中检测到和功率因数相关的参数(电功、电流、有功功率)送主控单元,CPU计算出功率因数,将其和功率因数上下限比较,发出投切电容器的命令。Reactive power compensation is a key project in the power system.The paper realizes the switching of the shunt capacitors through the reactive power automatic controller,thus to ensure that the power factor changes within the specified acceptable range,and finish the reactive power compensation.With the CS5460A as the core,the parameters（electrical power consumption,current,active power） related to the power factor detected in the power grid is sent to the main control unit,the power factor is calculated by CPU,and is compared with the upper and lower limits,and then the command for switching the capacitor is given.
