Maximum Power Point Tracking Control Scheme for Grid Connected Variable Speed Wind Driven Self-Excited Induction Generator

摘要: This paper proposes a wind energy conversion system connected to grid using self-excited induction generator (SEIG) based on the maximum power point tracking (MPPT) control scheme. The (IG) is controlled by MPPT below base speed and can be captured from turbine. Therefore, stator currents of IG are optimally indirect field orientation (IFOC) according in order maximize generated SEIG feeds (CRPWM) converter which regulates DC-link voltage at constant value where varied. Based d-q axes dynamic model synchronous reference frame orientation, high-performance current controllers with satisfactory performance designed analyzed. Utilizing these IFOC, fast response low harmonic distortion attained. regulated CRPWM inverter. By virtual flux regulators for inverter, response, unity factor achieved. complete has been simulated different velocities. simulation results presented illustrate effectiveness proposed scheme system. In results, controller give prominent command load regulation characteristics.
