关于DFIG的低压穿越能力的研究。对以后实现低压穿越做一些探索性的工作(Along with the sharp increase in the proportion of wind power supply some areas the impact of Large-scale wind farms for the stability of regional power grid is more significant. The research on low voltage ride-through (LVRT) of wind power system based on doubly-fed induction generators (DFIG) becomes a hot issue. In this paper ,Firstly introduces the concept of low voltage ride-through technology, The standards of LVRT of some European countries are presented, And then analyses and compares the kinds of common realize low voltage ride- technology and improve control strategy. The transient characteristics of DFIG when the grid voltage sagging.)
