Through systematically analyzing the mathematical theory knowledge of the small and medium-sized direct-drive permanent magnet wind power system, this paper has designed a rated power of 3kW wind power system under the environment of PSIM9.0 software. The wind power system model has been built, the back-to-back double- PWM control circuit has been designed and the simulation analysis has been completed. In the circumstance of wind speed changes, the simulation results show that the output power of the generator side is stable and the DC voltage of the inverter side is constant, which suggests the correct control strategy, the favorable system stability, and the achieved design goal. The work already done in this article provides a good platform and infrastructure for systematically analyzing the small and medium-sized wind power system.
