摘要
首先介绍了电机运行的两种节能原理。能量回馈器可将释放的机械能转换为电能回送给电网,是一种回馈型节能装置。再者介绍了全可控能量回馈器(ActiveControllableEnergyFeedbackDevice,简称ACEFD)的工作原理、电压自适应和交直流电流闭环控制策略、仿真和实验结果。应用实例表明,ACEFD具有显著的节能效果,在工业现场运行安全可靠,有很大的推广价值。
This paper presents two energy-saving principles of motor operation.Energy feedback device, an energysaving device,is able to transfer mechanical energy to electrical energy and send it back to electrical network.The principle of Active Controllable Energy Feedback Device （ACEFD） is analyzed,the voltage adaptive control and AC and DC closeloop control strategy are introduced, and then simulative and experimental results are conducted here.The applied instance indicates that the device has notable energy-saving effect.lt operates secure and reliable and possesses enormous value of popularization.
