A Method for FRT Capacity Enhancement of DFIG Based Wind Farm Using Saturated Core Fault Current Limiter

摘要：

　　The short circuit level increase and fault ride-through(FRT)are the main issues of doubly fed induction generator(DFIG)based wind farm.In this paper,a new method of using saturated core fault current limiter(SCFCL)to improve FRT capability of DFIG-based wind farm is proposed.During fault condition in the grid,SCFCL not only limits the fault current but also contributes to maintain the stability of the generator terminal voltage and decrease the peak value of DC-link overvoltage at the instant of fault occurring.Accuracy and capability of the proposed method are confirmed by simulating a sample power system in MATLAB/Simulink software.Moreover,enhancement of different SCFCL impedance values and different installation locations are compared.
