Injection of reactive power into the grid by polar voltage control technique for wind power applications

This study proposes a novel technique for integration of off - shore wind generation system to conventional grid. The technique is used to control the output of voltage source inverter. Output voltages of inverter are synthesized by using space vector pulse width modulation (SVPWM) in stationary reference frame. In this control scheme, control voltages are obtained in polar form and hence SVPWM implementation is easier at constant switching frequency. The scheme can be used for the control of induction motor drives exploring furthermore, solar power based drive applications such as agricultural pump-sets, compressors, fans etc. The simulation study is carried out in MATLAB/SIMULINK on a 100KVA inverter.
