中文摘要:以双馈异步风力发电机为背景,在风速不断变化前提下,分析变流器的内部控制策略。以模糊PI控制策略为基础,引入Smith预估分析模型,采用PI调节,并对变流器控制策略进行优化,增强系统的稳定程度。通过PSCAD工具开展分析,当风速出现波动时,基于Smith预估模型自适应模糊PI策略能够提升变流器的运行特性,增强系统鲁棒性。

Research and Design of Doubly-fed Wind Power Generation System Converter
Abstract:This paper based on the background of Doubly-fed induction wind generator, under premise of the changing wind speed ,the control strategy of the converter is researched. Based on the fuzzy PI control method, this paper introduced the Smith predictive model, used fuzzy adaptive PI controller strategy to control the converter,optimized the method of converter control, improved the stability of system. PSCAD software is used to simulate, the simulation results show that, under the influence of the wing speed changes, using fuzzy adaptive PI control based on Smith prediction strategy can improve the effect of converter control, and improve the robustness of system.
