Abstract According to the doubly-fed motor starting control technology specialty, this paper proposes a new doubly-fed motor starting control method. Using detection circuit to monitor rotor voltage of doubly-fed motor in starting process, this method realize the smooth transition from the asynchronous mode to doubly-fed model by controlling the transient output of inverter. On this basis, built control platform based on PLC and general converter, study the related experiment. Theoretical analysis and experimental results show that the proposed control method is feasible, and suitable for doubly-fed motor starting control process, so it has great practical value.
