摘　　要：运用机构原理解析方法,对大型风电机组的多个机构模型进行数学建模。在风速低于额定风速的情况下,采用传统PID回馈控制;在风速高于额定风速的情况下,加入模糊控制调节,使得风电机组在输出功率稳定性、系统可靠性等方面性能显著改善。In this paper,the mathematical modeling of multiple mechanism models of large wind turbine was carried out by using the method of mechanism analysis.When the wind speed is lower than the rated wind speed,the traditional PID feedback control is adopted;when the wind speed is higher than the rated wind speed,fuzzy control is added to improve the performance of the wind turbine in terms of output power stability and system reliability.
