    This research aims at system implementation for the soft start operation of a doubly-fed induction motor (DFIM) based on stator flux vector control. In this paper, the theory is briefly discussed. The simulation is performed using PLECS software to validate the hypothesis. A 5 kW wound rotor induction motor (WRIM) mechanically coupled with a simulated load is setup for the experiment. The STM32F407 microcontroller is applied to control the experimental system. Moreover, the Modbus protocol is applied for communication between the microcontroller and the computer using RS485 standard. The problem about rotor angle correction before enabling the MSC, which does not appear in the simulation, is seriously discussed. The experimental results do substantiate the proposed method and can be practically applied to the real system.

    Analysis of a Doubly-Fed Induction Motor for Soft Start Operation Based on Stator Flux Vector Control
    (2024-10-01)
    Suwan-Ngam, Warachart
    This paper aims at analysis of an operation of a doubly-fed induction motor (DFIM). The paper mainly focuses on the soft start method for the DFIM based on stator flux vector control and the conventional topology without either circuit reconfiguration or change in the control methods. Likewise, the details about reactive power control are also discussed. With the proposed method, the DFIM can start from standstill to any speed by controlling the machine-side converter (MSC). The computer simulation is performed to a 5 kW wound rotor induction motor using PLECS software. The simulation results have successfully validated that the DFIM can operate from standstill to any speed with only a single circuit configuration and a control scheme.
