摘要
随着人们对风能利用的重视,风电装机总容量逐年提升,装机叶片数量不断增加。为追求单个风力发电机更大发电量和更高能量转化效率,人们不得不增大叶片尺寸。装机叶片的数量和叶片尺寸的增长给叶片的检测带来不便。叶片作为风力发电机中将风能转化为机械能的核心部件,面对多变的环境和复杂的应力耦合作用,极易发生故障和损坏。为了安全生产,使经济效益得到保障,同时预防灾难性事故的发生,现已发展出多种对风机叶片的检测手段。
With the gradual depletion of global stone energy and the deterioration of the Earth′s ecological environment,people have begun to pay attention to the use of wind energy.On the one hand,wind power generation,as the most important way to utilize wind energy,has increased its total installed capacity year by year,which has led to an increase in the number of wind turbine blades.On the other hand,in order to pursue greater power generation and higher energy conversion efficiency of wind turbines,it is achieved by manufacturing larger-sized blades.The number of blade operations and the increase of blade size bring a lot of inconvenience to the detection of the blade.As one of the core components of wind turbines,blades can convert wind energy into mechanical energy.In the process of energy conversion,the blade needs to face variable environmental factors and complex stress coupling,which is prone to failure and damage.In order to ensure the safe production and economic benefits of wind power generation and prevent the occurrence of catastrophic accidents,various methods have been developed to timely detect wind turbine blades.
