The invention provides a doubly-fed asynchronous wind power generation system. The system comprises a doubly-fed wind power generation unit, a grid-connected inverter and a monitoring upper computer in connection. The doubly-fed wind power generation unit comprises a base, a three-phase asynchronous variable-frequency speed regulating motor and a doubly-fed power generator, and the three-phase asynchronous variable-frequency speed regulating motor and the doubly-fed power generator are mounted on the base. A coupler is arranged between the three-phase asynchronous variable-frequency speed regulating motor and the doubly-fed power generator. The grid-connected inverter comprises a cabinet, a frequency converter, a current converter, a sensor and a processor, and the frequency converter, the current converter, the sensor and the processor are arranged in the cabinet. The frequency converter is connected with the three-phase asynchronous variable-frequency speed regulating motor, the current converter is connected with the doubly-fed power generator, the sensor is respectively connected with the current converter and the processor, and the processor is connected with the monitoring upper computer. The doubly-fed asynchronous wind power generation system has advantage of high pertinence, functional maturation, large quantity of demonstrative experiments and convenience for onsite practical teaching research.
