Laser Wind Radar-Based Feed Forward Con-trol of Wind Turbine Nacelles with Wind Power Performance Study
摘要: 由于人类对于能源的需求逐步上升,对能源的质量与效率要求越来越严格,如何高效地利用风能是当今能源领域研究的热点。因此,本论文主要针对激光测风雷达技术进行风电机舱前馈控制的应用研究。通过前馈控制作用于风机偏航机构与反馈控制系统共同控制风机桨距角,达到更加精确的对风,提高风能的利用效率,也解决了风机齿轮箱磨损老化等问题。
Abstract:
Due to the rising demand for energy and the increasingly stringent requirements for energy quality and efficiency, the efficient use of wind energy is a hot topic of research in the field of energy today. Therefore, this thesis focuses on the application of feed-forward control of wind turbine nacelles by laser anemometer radar technology. Through feed-forward control, the wind turbine yaw mechanism and the feedback control system jointly control the pitch angle of the wind turbine to achieve more accurate wind alignment, improve the efficiency of wind energy utilization, and also solve the problems of wind turbine gearbox wear and aging.
