Abstract This Paper presents a variable frequency control to regulating the voltage and frequency for self excited six phase induction generator. The approach based on the dynamic model of wind turbine, SPSEIG, Rectifier and IGBT based voltage source inverter, which keeps the generated voltage constant contempt the change in the connected static load. The computer model of d-q axis has been developed in an arbitrary reference frame and also the effects of common mutual leakage inductance between the two three-phase winding sets are included. The comparative analysis of scalar and vector control scheme is derived for studying the behavior of the system under transient and dynamic conditions. The proposed Variable Frequency Control (VFC) based system is configuring with the 12 pulse ac-dc-ac converter to reduce the harmonic contents of the designed system. As meet the requirement of prescribed scheme is found offering high reliability, improved capability of voltage and load withstanding along with acceptable efficiency. The Space Vector Based Direct Torque Control (SV-DTC) has been carried out better reduction of harmonics compared with scalar control scheme. The Total Harmonic Distortion (THD) is evaluated based on Fast Fourier Transformation (FFT) analysis of voltage and frequency regulation waveforms. The proposed configuration is developed in MATLAB/SIMULINK environment and Power System Toolboxes.
