摘要
变速恒频双馈风力发电机组以其独特的技术优势已逐步成为并网型风力发电机的主力机型,而直接转矩控制技术在双馈电机中的应用是一个研究热点。文章对变速恒频双馈风力发电机的直接转矩控制技术进行了理论分析,阐述了它的工作原理和系统结构,并对目前主流控制方案如积分变结构、模糊DTC、遗传优化模糊等给予分析、说明,并论述了此类型控制的研究方向。
VSCF doubly fed wind turbine has gradually been the main model of grid-connected wind turbines with its u- nique technological advantage, and the application of direct torque control technology in DFIG is a hot topic. This paper fo- cused the analysis on the direct torque control technique of variable speed constant frequency DFIG, explained the working principle and system architecture. It showed the research of this type and explanation the mainstream programs as integral variable structure control, fuzzy DTC, genetic optimization of fuzzy etc.
