Research on Short-Circuit Voltage of Wind Turbines with Doubly Fed Induction Generator

Abstract

This paper introduces the structure and working principle of doubly fed induction generator, and then establishes mathematical model of DFIG, uses MATLAB simulation environment and set parameters, establishes simulation model. Finally, the simulation results of DFIG grid voltage fault (mainly short circuit fault) are analyzed, the voltage and current waveforms are obtained, and the objectivity of the model is verified, which lay the foundation for the future research on fault control research.
