Abstract :
This paper from the point view of wind farm fault ride-through (FRT) capability, discusses the performance of converter protection schemes to it. Different resistor protection methods are summarized and then a new combined protection with crowbar (CB) and series dynamic resistor (SDR) is proposed. With the analysis of rotor current during fault, resistance values are calculated for practical application. The rotor high current reduction performance is simulated with MATLAB/Simulink. Fault ride-through performance including the reactive power supply, torque fluctuation and rotor speed with crowbar and series dynamic resistor are compared. The proposed method is an alternative for further protection and requirements of wind farm riding-through grid disturbances.
