PWM方案控制补偿电容的自动无功补偿装置

The Auto Compensation Device by Control Capacitor with PWM Scheme

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

Advance a new opinion that the controlled volume in auto compensation device should be capacitor,and the variable volume of capacitor should be controlled by PWM technology Compared with FCT+FST auto compensation device,the opinion is of many advantage
