Abstract The integration of large capacity wind farm may pose certain influence to power networks. This article introduces the model and control strategy of doubly-fed induction generator (DFIG) belonging to variable speed constant frequency (VSCF). The analysis of its operational characteristics confirms the facts that integration of large wind farm will impact power networks significantly, including frequency fluctuation, voltage deviation and fluctuations, deterioration of transient stability. Some measures for improvement are proposed. By the model of Nantong grid which is built in PSS/E. The emulation results demonstrate the correctness of the analysis above both in wind speed fluctuation and system fault.

Key words： Wind power integration DFIG frequency fluctuation voltage deviation transient stability
