Abstract:
In this paper, the performance of a combination of Static Synchronous Compensator(STATCOM) and super-capacitor is investigated in order to improve grid and load connected Permanent Magnet Synchronous Generator(PMSG) variable speed wind turbine.The operation of STATCOM and super-capacitor in both normal and fault conditions are studied. Furthermore, a nonlinear local load is connected to wind turbine to find out a control method for elimination of current harmonics produced by this load.Moreover, a proper controller is proposed to produce modulating signals for wind turbine inverter which maintains THD less than 5% which is an IEEE standard.An LCL filter is designed as an inverter output filter for decreasing harmonics caused by switching.STATCOM and IGBT inverter controllers are respectively designed by d-q synchronous frame and space vector pulse width modulation(SVPWM) in order to maximize the operation of Wind Energy Conversion System(WECS).Simulations are done in MATLAB/SIMULINK.Results show that voltage stability,power factor correction and STATCOM injection/absorption of reactive power are happened correctly during voltage fluctuations caused by Three-phase faults
