In order to study the influence mechanism of rotor-side converter and its control system on damping characteristics of doubly-fed wind turbine, a dynamic model of the wind turbine under small disturbance state is constructed considering mechanical torque, electromagnetic torque, transient potential, rotor-side converter control, voltage control and angle offset. Then, the damping torque and synchronous torque expressions of the doubly-fed wind turbine are derived based on the complex torque coefficient method. The damping torque is related to the oscillation frequency, wind speed, mechanical parameters, electrical parameters and control system parameters of the wind turbine, and the control parameters of the inner and outer loops of the rotor-side converter are coupled with each other to affect the damping of the wind turbine. Finally, the mathematical model is verified by time domain simulation and frequency domain simulation. The results show that the model has applicability at different oscillation frequencies.
