Abstract: With wind power generators of hydraulic transmission type as the research object,the mathematical model of the fixed displacement pump-double variable displacement motors speed regulating system, the permanent magnet synchronous generator and wind turbine were established aiming at the actual situation of hydraulic component in speed regulation circuit. The mathe-matical model of fixed displacement pump-double variable displacement motors speed regulating system was established through the AMESim. The mathematical model of permanent magnet synchronous generator and wind turbine were established through the MATLAB/Simulink., Using the method of fuzzy control,the VSCF generator speed characteristics was theoretically analysed, Re-search shows that the fixed displacement pump-double variable displacement motors speed regulating system can make the perma-aasoasa

风能作为清洁可再生能源,受到国内外研究工作者的广泛关注。风力发电作为风能的主要利用形式已成为解决各国电力和能源紧缺的重要战略选择。风力发电机组经历了恒速恒频到变速恒频的发展过程。风电发展初期的恒速恒频风力发电机组,由于要保持风轮恒速,必定使风力机捕获的风能大大降低,

造成风能的巨大浪费;恒速恒频系统中采用的异步发电机的励磁电压需要从电网获取,消耗部分无功功率。由于以上缺陷,恒速恒频风力发电机已退出历史舞台。变速恒频风力发电机组目前主要有两种发电形式,一种是双馈式发电机组,另一种是直驱式发电机组。双馈发电机系统具有中间机械传动环节一增速齿轮箱,存在滑环、电刷和双绕组,使得零件的制造和原料成本增加,齿轮箱的故障率较高,而且不易
