【摘要】 无功补偿是节能降耗，提高效率的有效手段。采用电力电容器进行补偿有固定补偿和随机自动补偿。自动补偿的核心是控制器，解决控制振荡，实现准确投切，电容器才能得到最佳补偿效果。更多还原

【Abstract】 Nonpowr compensation is the effective way to save energy,reduce consumption and raise the efficiency. Fixed compensation and random auto-compensation use power capacitor to compensate. The controller is the core of the auto-compensation,which controls vibration to command accurately and makes capacitor achieve the best compensation results.更多还原
