摘要: 近年来,国内发生了多起风力发电机叶片扫塔故障,严重影响风电机组安全运行,同时也造成了大量的经济损失。从净空设计、吊装维护、叶片质量、机组运行控制、场址适应性、仿真还原等方面对某风场叶片扫塔故障原因进行分析,确定风场叶片扫塔由湍流超限、负切变、叶片安装角错位共同导致,并针对不同扫塔原因给出预防措施,为新机型净空设计提供一些建议。

Abstract: In recent years, there have been a number of blade tower sweeping failures of wind turbine in China, which have seriously affected the safe operation of wind turbines, and also brought a lot of economic losses. This paper analyzes the causes of blade tower sweeping failure in a wind farm from the aspects of clearance design, hoisting maintenance, blade quality, unit operation control, site adaptability, simulation restoration, etc. It is determined that the blade tower sweeping in the wind farm are caused by turbulence overrun, negative shear, and blade installation angle dislocation. Preventive measures are given for different tower sweeping causes, and some suggestions are put up for the clearance design of new models.

Key words: wind turbine blades, blade sweeping tower, extreme wind conditions, negative shear, turbulence intensity
