With wind power generators of hydraulic transmission type as the research object, the mathematical model of the fixed displacement pump double variable displacement motors speed regulating system ,the permanent magnet synchronous generator and wind turbine were established aiming at the actual situation of hydraulic component in speed regulation circuit. The mathematical model of fixed displacement pump double variable displacement motors speed regulating system was established through the AMESim. The mathematical model of permanent magnet synchronous generator and wind turbine were established through the MATLAB/Simulink. Using the method of co-simulation, the VSCF generator speed control was theoretically analysed. Research shows that the fixed displacement pump double variable displacement motors speed regulating system can make the permanent magnet synchronous generator speed stability.
