摘要

摘要提出了一种新的用于表示风力机作动盘数值模型中体力的广义解析模型,并与叶片元动量(BEM)模型的结果进行了比较。该模型是先前开发的负载模型的扩展,该模型基于转子盘受到恒定循环的影响,修改了尖端和根部效应,对应于最佳设计情况。通过添加抛物线循环分布,对应于近尾迹的固体流动方式,可以考虑与非设计情况相关的损失,对应于高风速下的螺距调节。该模型的优点是,它不依赖于任何有关实际风力涡轮机的详细知识,而只需要有关推力系数和叶尖速比的信息。该模型在不同的风力机运行条件下进行了验证。比较表明,即使在很小的推力系数和叶尖速比下,与边界元模型的一致性也很好。

Generalized analytical body force model for actuator disc computations of wind turbines
Abstract. A new generalized analytical model for representing body forces in numerical actuator disc models of wind turbines is proposed and compared to results from a blade element momentum (BEM) model. The model is an extension of a previously developed load model, which was based on the rotor disc being subject to a constant circulation, modified for tip and root effects, corresponding to an optimum design case. By adding a parabolic circulation distribution, corresponding to a solid-body approach of the flow in the near wake, it is possible to take into account losses associated with off-design cases, corresponding to pitch regulation at high wind speeds. The advantage of the model is that it does not depend on any detailed knowledge concerning the actual wind turbine being analysed but only requires information about the thrust coefficient and tip-speed ratio. The model is validated for different wind turbines operating under a wide range of operating conditions. The comparisons show generally an excellent agreement with the BEM model even at very small thrust coefficients and tip-speed ratios.
