交流差频电力测功机的方案研究

The Scheme Research of AC Difference Frequency Electric Power Dynamometer

本文论述的“交流差频电力测功机”方案是一种节能型电力测功机。测功电机定子直接接电网 ,转子与内燃机同轴连接 ,差频发生器给转子绕组提供一个电压和频率可调、相序可变的三相交流电源 。

This paper presents a scheme of 'AC difference frequency' for an energy saving type electric power dynamometer.The stator of electric machine is directly linked to a power supply net,and it's rotor linked to an internal combustion,at the same time,a adjustable voltage,a adjustable frequency and variable phase order three phase AC current is provided by an AC difference frequency generator.The goal is realized for recycle of internal combustion test energy.
