| Abstract: | It is researched of control strategy suitable for direct-drive grid side converter in wind power system based on SVPWM.The topology with PWM six bridge arms powered by three-phase voltage is adopted.A mathematical model of the grid side SVPWM converter is established.Based on grid voltage oriented vector,the control strategy with dq axis current linearization decoupling and a novel P＋resonant control strategies are adopted.The simulation results show that the system has excellent performance with the advantages of stable operation,fast transient response,stable output DC voltage and tiny ripple. |
