提出自动无功补偿装置的被控制量应为补偿电容 ,且应利用PWM (脉宽调制 )技术控制补偿电容的等效电容量。与FCT +FST自动无功补偿装置相比较具有许多优点
It is proposed that the controlled variable of the automatic reactive power compensation device should be a compensation capacitor, and the equivalent capacitance of the compensation capacitor should be controlled by PWM (Pulse Width Modulation) technology. Compared with FCT + FST automatic reactive power compensation device has many advantages
