Abstract
This work proposes a hybrid wind power generation system connected to the power grid through a back-to-back converter. The Grid Side Converter (GSC), connected to the eletric grid via an L filter, mitigates harmonic currents and corrects the power factor of a non- linear load connected to the Point of Common Coupling (PCC). The Machine Side Converter (MSC) implements the Rotor Field Oriented Control (RFOC) in dq Synchronous Reference Frames (SRF). This technique enables independent and decoupled control of the torque and magnetization of the Squirel Cage Induction Generator (SCIG). The torque reference is obtained through the Maximum Power Point Tracking - Optimal Torque (MPPT-OT), this method tracks the maximum power point based on the calculation of the optimal electromagnetic torque obtained from the measurement of the mechanical speed of the generator.
