摘要
为研究双馈风电机组变速恒频运行时发电机的特性,应用小扰动分析方法建立了双馈发电机的线性模型。结合机组典型工况点上线性模型的极点分析,总结出发电机在变速运行中动态特性变化的规律。分析结果为双馈发电机控制系统设计及控制器参数整定提供了参考依据。
Variable-speed constant-frequency operating of doubly-fed wind turbine requires deeper research on generator characteristic,small disturbance analysis method was adopted to establish DIFG linear model.Base on pole positions analyzing of models on certain typical operating points,generator plant dynamitic characteristic vary trends were summarized,which support reference for DIFG control system design and PI controller tuning.
