用智能电网降低电压以减少电耗

Trimming voltage to reduce power consumption by smart-grid

介绍美国一项应用智能电网节能的新技术,该技术已在基础研究和设备试验方面进行了十多年的工作,正处在工业应用阶段。其节能效果可达总能耗的3%,这相当于美国所有电冰箱的用电量,而且无需用户介入操作,可避免一些不必要的应用阻力和困难。这项技术被称为"降低电压节能(CVR)"技术,其实质是将用户侧电气设备的用电电压稍作降低,以减少设备产生的磁场辐射能,使其在不影响工作效果的前提下减少用电量,从而达到节能的目的。

An US experience of trimming voltage to reduce power consumption was introduced. This new conservation technology has passed more than ten years of basic research and device tests. It is now in the phase of industrial application. It offers utilities a big conservation opportunity with Smart-Grid support, and could reduce nation＇ s power consumption by 3%, which is the equivalent of all refrigerators consumption in US. The Conservation Voltage Reduction （CVR） reduce the strong magnetic field which throwing energy away by lower customer side voltage. It is especially effective for induction motors used in dozens of electric devices. Trimming voltage could reduce power consumption, and consumers need not lift a finger.
