The depletion in the fossil fuel and increase in global warming has shifted the focus of researchers to green alternative energy. Wind power electrical generation is one such alternative where the kinetic energy of wind power is harnessed to generate green electrical power. India, being the fourth largest wind power generator has attracted numerous researchers towards the improvement of wind energy conversion system. This paper also presents improved controller techniques for a Permanent Magnet Synchronous generator (PMSG) based wind turbine coupled with Cascaded Quadratic Boost Converter (QBC) and Space Vector Modulation (SVM) based inverter. The digital simulation and execution of PMSG based wind turbine a long with QB Converter and SVM Inverter in a closed loop is presented. The closed loop is realized using Proportional Integral (PI) and Fractional Order Proportional Integral (FOPI) controllers. Initially, the AC power from PMSG wind turbine is converted to DC using bridge rectifier. The DC output from the rectifier is then boosted to the required level using quadratic boost converter. The output from QB converter is then fed to the SVM inverter. The closed loop investigations are carried with PI and FOPI controllers. The simulation results of both PI and FOPI controlled QBC are compared. The outcome of FOPI controller represents that the steady state error and settling time are reduced when compared to PI-controlled closed loop quadratic boost converter.
