摘　　要：针对异步电机定子变频在解决高压电机调速时,对输出电压的等级要求高,对调速技术要求不足,在原有仅采用控制触发增量方法的基础上加入了闭环控制。在Matlab/Simulink仿真软件中,通过在仿真模型中引入S函数,建立了定转子分段变频有级调压闭环调速系统的仿真模型,并以双变量变频器为基础设计了实验电路,编写了实验程序,从仿真和实验两个方面对定转子调速系统的性能进行分析研究。得出双变量交交变频器在绕线式异步电动机转子侧供电实现调速时具有一定的可行性。Due to the nique in solving the retical research of a insufficiency of the high-level requirements of output voltage and speed regulation tech- problem of high-voltage asynchronous motor speed regulation on the stator-side,the theo- closed-loop speed regulation was done by the basis of multilevel voltage regulation con- cept. S function was introduced in Matlab/Simulink simulation software, and the simulation model of a seg- mental variable frequency closed-loop speed regulation system with multilevel voltage regulation on the stator- side and rotor-side was built in Matlab/Simulink. Experiment circuit was designed and programmers were writ- ten by the dual-variable cycloconverter. The performance of speed regulation system at the stator side variable frequency and the rotor side variable frequency was analyzed by both simulation and experiment ways. The re- suits show that it is possible when power supply and speed regulation is on the rotor-side of wound asyn- chronous motor with the dual-variable cycloconverter.
