Abstract :
This paper firstly analyzes the stability conditions of cascade brush-less doubly-fed induction machine(CBDIM) by means of the small signal linear model and Lyapunov theorem. Then the simulation including CBDIM, cyclo-converter, vector control system and the whole system experiment is done. Finally it draws a conclusion that CBDIM drives have the same performances as the DC drives and the simulation results are in excellent agreement with the experiment according to the experiment under the typical working condition. The CBDIM drives which is firstly developed in China makes a contribution to the wide application to some extent in variable-speed constant-frequency generators in the future.
