摘　　要：交流异步电机已广泛应用于各种工业领域,现代传动系统主要由"变频调速系统-电动机-工作机械"组成,而电机的制动往往是变频器设计的重点。本文提出一种由电阻能耗制动和双频制动相结合的新型制动方法,结合了这两种制动方法的优点,给出了控制算法流程图,并通过电力系统仿真软件PSCAD进行了仿真研究,对电机转速,逆变器输出频率及输出A相电流进行了监测,结果表明该方法具有很好的制动效果,各项性能指标均达到设计要求。Motors are used more and more widely in modern industry manufacture .In order to get quick stop for motors, the paper designed a novel stopping method for motors operating from resistance and variable frequency drives. A control arithmetic flow chart is put forwardf--finally, a simulation research is carried out. The simulation is successful and the advantages of the stopping system are proved by the result.
