摘　　要：自动电压控制(AVC)系统的投入对保证风电场的电压稳定有重要作用,现有研究对风电场的自动电压控制无功分配策略缺乏深入分析。本文在现有自动电压控制无功分配模式的基础上,采用含有静止无功发生器(SVG)和风力发电机的小干扰模型,分析自动电压控制无功分配策略对风电场稳定性的影响。该方法计及自动电压控制系统中无功分配模式对风电动态稳定性的影响,可指导实际生产。通过对某实际风力发电机的算例分析,验证了方法的有效性。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.
