摘要：
In recent years, with increasing complex grid environment and growing wind power penetration, the operation technique of doubly fed induction generator (DFIG) under nonideal grid conditions, including harmonic distortion, voltage unbalance, and voltage dip, has been a research hotspot. Under harmonic distorted and unbalanced grid conditions, some enhanced control strategies can be used to improve the performance of the DFIG itself or to benefit the power quality at the point of common coupling. When the grid voltage dips, protecting measures based on software or hardware are required to keep the DFIG connected to the grid and support the voltage restoration by providing reactive power. In this paper, the existing researches in the aforementioned fields are reviewed. Different technical solutions for DFIG operating under non-ideal grid conditions are compared, then the technical trends and potential research topics are discussed and prospected. © 2020, Electrical Technology Press Co.
