摘　　要：电力测功机由负载电机及其变频控制装置组成,工作在第二象限。针对其再生能量,对比分析了几种常用的能量处理方式,主要介绍了能量回馈单元的主电路及其控制电路设计,并进行了仿真分析和试验研究。结果表明,该能量回馈单元结构简单、控制容易,实现了再生能量的高效率回馈电网。Electric dynamometer is made up of a load machine and the variable frequency equipment which operates in second quadrant. Aimed to the disposal of the regenerative energy, a few methods which usually used are analyzed comparatively, then an energy feedback unit including the main circuit and the control method was mainly introduced, and the simulation analyzing and the experiment research were achieved. The results verified the feedback unit has simple structure and is easy controlled, so, high effective feedback of the regenerative energy is implemented.
