Abstract
Aims: This paper presents the control of the output torque of SCIG using indirect vector control (IVC) technique.
Study Design: IVC is very popular in industrial applications, which doesn’t rely on the measurement of the airgap flux because the devices that used to measure the air-gap flux is inaccurate in low speed. The IVC technique has been presented to control the torque of the generator and maintain the flux unchanged.
Methodology: The performance of the proposed system is tested using MATLAB/SIMULINK.
Results and Conclusion: Simulation results are introduced showing improvement control system performance.
Keywords: Induction generators, field orientation, modeling and simulation, torque control
