Indirect Field Oriented Vector Control for Five-Phase Open End Winding Asynchronous Generator in Wind Energy System

–– This research study describes a potential method for controlling a five-phase open-end winding squirrel cage induction generator in a wind energy conversion system. The method aims to maximize power extraction from the wind by implementing an indirect field-oriented control strategy. An open-end winding refers to a type of electrical winding configuration where one end of the winding is left unconnected. Squirrel cage induction generators are frequently employed in wind energy conversion systems. Wind energy systems employing open-end winding multiphase generators have diminished torque fluctuations, decreased current per phase, & possess the ability to operate with faults. The term “multi-phase” denotes a phase number larger than three. The rotor field-oriented control technique aims to produce high dynamic performance in open-end winding induction generators by separating control of the electromagnetic torque and rotor flux. This allows the generator to adapt to different wind speed circumstances. In this research, a mathematical model for an open-end winding, five-phase squirrel cage induction generator is developed, and the steady state is assessed using an indirect field-oriented vector control technique. The MATLAB/SIMULINK environment is used to extract the appropriate electromagnetic torque, stator currents, stator voltage, along with speed variations. The final results compared to those of conventional approaches.
