摘要
针对风电机组偏航系统累积轴承损伤对其对风效果及使用寿命造成的影响,从偏航系统机械结构与运行原理出发,引入2种疲劳损伤表征参数,用于指导偏航系统优化控制器设计。在基于经验的模糊偏航控制策略基础上,利用遗传算法和偏航疲劳损伤参数对模糊规则进行优化,有针对性地实现了偏航对风过程中偏航系统疲劳载荷的有效抑制,并利用所提出的控制策略进行了多工况仿真实验。结果表明:相比现有控制策略,所提出的遗传模糊偏航控制策略可明显降低偏航系统疲劳程度,有效减少偏航系统损伤。
Aiming at the influence of the accumulated bearing damage of the wind turbine yaw system on its wind effect and service life,according to the mechanical structure and operation principle of the yaw system,two kinds of fatigue damage characterization parameters were introduced to guide the optimal controller design of the yaw system.Based on the empirical fuzzy yaw control strategy,the fuzzy rules were optimized by using genetic algorithm and yaw fatigue damage parameters,and the bearing fatigue load were effectively suppressed by yaw system during the wind process.The proposed control strategy was applied to carrying out multi-condition simulation experiments.Results show that compared with the existing control strategies,the proposed genetic fuzzy yaw control strategy significantly reduces the fatigue degree of the yaw system,and effectively decreases its damage.
