Abstract:
This research paper deals with the performance analysis of wind energy conversion system during grid fault conditions. In most of the surveys, the DC link voltage oscillations are not regulated properly as per the safety required safety factor limit during various grid fault conditions. Regulating the DC link voltage and minimising its oscillations during grid fault condition is very essential in the interconnected power system. Failing to provide proper DC link voltage regulation will affect the connected converter topologies and also the controllers associated with it. In order to overcome the drawbacks faced in the previous research works, sliding mode PI controller is designed and it is mathematically modelled towards the grid side converter. The simulation results are obtained for symmetrical and unsymmetrical fault using MATLAB Simulink software.
