Harmonic Analysis of Stator Current for Grid Connected Five Phase Open End Winding Squirrel Cage Induction Generator Using Indirect Rotor Field Oriented Control Technique with Three Level Rectifier

The rising need for renewable energy sources requires the optimization of power generation systems, especially in wind energy applications. The five-phase open end winding induction generator offers benefits such as less torque ripple and improved fault tolerance relative to conventional three-phase systems. The Indirect Rotor Field Oriented Control Technique for five phase open end winding squirrel cage induction generator separates the control of electromagnetic torque and rotor flux, allowing for accurate regulation of generator output in fluctuating wind conditions. The control technique utilizes a three-level rectifier to enhance power conversion efficiency, resulting in a more stable voltage output during various wind speeds and diminished harmonic distortion. This paper examines the performance of application of Indirect Rotor Field Oriented Control Technique for Five Phase Open End Winding Squirrel Cage Induction Generator in wind energy systems, coupled with a three-level rectifier. The simulation findings illustrate the harmonic distortion of stator current with three level rectifier is better than two level rectifiers for Five Phase Open End Winding Squirrel Cage Induction Generator during step change in wind speeds.
