In order to solve the problem that the stability of the power grid will be affected by the lack of inertia and damping when the double fed wind turbine is connected to the outlet inverter, this paper first describes the whole control strategy of the doubly fed fan based on the virtual synchronous control. Then the control strategies of the rotor-side inverter and the grid-side inverter in the overall control strategy are introduced respectively, and the double-fed fan unit model with grid-side VSG control is built. Finally, the simulation analysis of the model is carried out through MATLAB/Simulink for the fault condition and different running wind speed of the power grid, and the simulation results of the original double fed fan model are compared and analyzed. It is verified that the double-fed fan with grid-side VSG controlhasbetter regulationcharacteristicsthan thedouble-fed fan.
