Abstract: Power conversion systems are used in wind turbine to improve the quality of the generated power without harmonic distortion which is utilized for transmission through grid intended for variable wind speed. However due to the variations of wind leads to evolving of high voltage and low voltage which leads to inconsistency in feeding power to grid. Inorder to provide quality constant harmonic distortionless power to grid from wind turbine an efficient Magnet Synchronous Generator (MSG) connected to the Modified H-bridge series connected Voltage Source Convertor (MHSVSC) is framed out. This converter can draw the input voltage with low distortion and thereby provides the output voltage with low harmonic distortion by LCL filter. Also, to meet the inconsistency in voltage supply to the grid, a fault ride requirement capability based on the M-controller is provided for the dc-link voltage to manage the voltage drop and over voltage in the grid. Thus, the power, which is to be supplied to the grid, is done cost efficiently, consistently, reduced harmonic distortion and errors by utilizing the MHSVSC with Fault Ride Capability. The proposed methodology implemented in the MATLAB platform.
