Abstract：At present, there is a lack of in-depth analysis on the automatic voltage control (AVC) strategy of wind farm, which plays an important role in improving the voltage stability of wind farm. On the basis of considering the existing reactive power distribution mode of automatic voltage control, the small signal model with static var generator (SVG) and wind turbine is adopted to analyze the influence of AVC system on the stability of wind farm. This method takes into account the influence of reactive power distribution mode on dynamic stability in automatic voltage control system, and has good guidance for actual production. The effectiveness of the method is verified by an example of a real wind turbine.
