Abstract :
With high penetrations of wind energy, different types of wind farm generators do not have the same fault transient characteristics that can complicate the selection and configuration of wind farm grid protection equipment. Incorrect selection of protection equipment will affect the stability and of the power systems. This paper investigates and analyzes the transient characteristics of doubly-fed induction generator (DFIG) under various short-circuit fault conditions for a typical distribution network. Firstly a detailed model of the DFIG and its principles is descried. A realistic of a 99 MW wind farm with 66 units of 1.5 MW DFIG is modeled using RTDS/RSCAD. The transient characteristic of the wind farm with the DFIG units have been analyzed under different short-circuit fault conditions. Results from the fault performance study on the distribution network are presented and discussed.
