A novel wind power generation system based on the speed regulation of permanent magnet double-rotor motor is proposed.Conventional synchronous generators are adopted in the last link of this system to the power grid.The system has overcome the shortcomings of doubly-fed and direct-drive wind power generation systems,while having high power quality and excellent grid-connection ability like conventional synchronous generators.The permanent magnet double-rotor motor has two mechanical ports and one electrical port,which makes it possible to realize the transfer and adj ustment of electric energy and mechanical energy at the same time.The working principle of the permanent magnet double-rotor motor is described in detail. A mathematical model of the double-rotor motor is set up based on the basic electromagnet relation of the permanent magnet motor.According to the working state of the wind turbine,a control strategy for the double-rotor motor is put forward.The results of simulation and experiment show the correctness of the theoretical analysis and the feasibility of the design.
