Research on grid-connected inverter of SRG wind power generation system based on SVPWM over-modulation scheme

Nonlinear mathematical model of SRG is established based on its actual characteristics. A novel algorithm of SVPWM over-modulation is proposed and the application of the inverter technology in SRG wind power system is analyzed in detail. Simulation results show that the energy feedback can be realized with inverter system on the basis of SVPWM over-modulation scheme and excellent electrical energy quality can be sent out with smooth amplitude, stable frequency, and low harmonic content.
