摘　　要：设计了一种以异步电机模拟负载的"双逆变器-电机"互馈式交流传动试验系统。结合高性能的矢量控制技术,采用转速转矩闭环独立控制,从而有效地提高了系统的实时性和稳定性。讨论了该试验系统的构成和运行原理,给出了试验系统的硬件实现,并在此基础上构建了实验系统。实验结果表明,该试验系统具有优良的动静态性能和较好的控制效果,在中大功率交流异步电机试验中,应用前景广阔。A ＂Twin Inverter--Motor＂ reciprocal power-fed AC drive experiment system was presented which uses the asynchronous machine as the simulation load. Combining high performance technology of vector control and using speed and torque independent closed loop control, the real-time performance and the stability of this system are effectively enhanced. The construction and operation principle of this scheme were discussed, then the hardware structure of the system was introduced, and the experimental system was developed in these foundation. The results indicate that this experiment system has excellent dynamic and static performances and high control effect,which can be widely used in test of the middle and large power asynchronous machines.
