| 摘 要： | 为了充分地研究风速波动、风向变化和电网扰动等外部激励对于并网双馈异步风力发电机组影响,利用Simpack与Matlab/Simulink软件为仿真平台,搭建了某MW级风力发电机组联合仿真模型,并结合风电机组在实际运行中的控制策略,对各外部激励与机械系统之间的相互作用关系进行了深入的研究。通过在湍流风条件下的时域计算结果,分析了齿轮副动态啮合力,并求解了在不同外部激励作用下,塔筒产生的振动响应。研究结果为风力机可靠性设计和动态性能优化奠定了基础。

| Abstract: | In order to fully research the effects of external excitations, such as wind speed, wind direction and voltage disturbance, on a grid connected wind turbine with doubly fed induction generator, a co-simulation model of MW-class wind turbine system is established by using Simpack and Matlab/Simulink software. Also, by considering the actual control strategies in the process of simulation, the relationship between external excitations and mechanical system is studied. According to time-domain simulation under the turbulent wind condition, the dynamic meshing forces of gears are analyzed. Besides, the vibration responses of tower are calculated under the different external excitations. Research results lay a foundation for dynamic performance optimization and reliability design of a wind turbine. |
