摘要

首先建立基于多翼型的偏航叶素-动量理论模型,用于计算偏航风力机的载荷;并基于此模型,建立包含风电场功率与载荷的尾流重定向优化目标函数,并提出一种新的风电场输出功率与载荷的联合优化策略;基于Matlab软件,搭建3×3的风电场模型并进行仿真研究。仿真结果表明,所提基于多翼型的偏航叶素-动量理论模型能准确计算偏航风力机叶片挥舞力矩,改进的尾流重定向优化与所提新型联合优化方法可在提升风电场功率的同时显著降低风电场载荷。

Abstract

This paper initially establishes a yawed blade-element momentum theory model grounded on multiple airfoil profiles, which is employed to calculate the loads acting on yawed wind turbines. Subsequently, based on this model, an objective function for wake - redirection optimization that comprehensively incorporates both the power output of the wind farm and the loads it bears is formulated, and a novel joint-optimization strategy for concurrently enhancing the wind-farm output power and minimizing its loads is proposed. Utilizing Matlab software, a 3×3 wind-farm model is constructed and undergoes simulation studies. The simulation results demonstrate that the proposed yawed blade-element momentum theory model based on multiple airfoil profiles can accurately compute the flap-wise moment of yawed wind-turbine blades. Moreover, the improved wake-redirection optimization approach and the novel joint-optimization method can significantly reduce the loads on the wind farm while effectively increasing its power output.
