| Abstract: | his paper presents the performance analysis of a doubly fed slip-ring induction motor.The motor stator is connected to the power supply of constant voltage and frequency and the rotor is fed by a GTR inverter of adjustable voltage and frequency. The motor speed is a function of the difference between the two supply frequencies. This system can achieve a control of two degrees of freedom on the rotor side, and its performance is independent of the rotor and stator resistance. Digital simulation and experimental results show that the performance is sans. factory and the system has broad prospects of application. |
