A synergetic control method is proposed to improve the fault ride through capability of front-end speed regulation wind turbine (FESRWT). In case of three-phase short-circuit fault and single-phase grounding fault, this method can accelerate the attenuation of stator flux transient component and restrain the fluctuation of rotor speed, make generator produce large reactive power which will provide more reactive power support for power grid, and improve the fault ride through capability of FESRWT. By dynamic analysis of the proposed algorithm, the large range stability constraint condition satisfying the fault ride through is obtained, and the parameter range satisfying the condition is solved by Monte Carlo method. Taking 2 MW FESRWT as an example, the control strategy is verified and analyzed. Simulation results show that the proposed method can improve the fault ride through performance of FESRWT.
