摘要
风力发电机组塔筒屈曲、叶片折断的主要原因是风力发电机组的实际载荷过大、疲劳强度不够等。为了避免此类情况发生,需要对风力发电机组的载荷情况进行测试。风力发电机组载荷测试是风力发电机组型式试验之一。风力发电机组各个部件的载荷直接影响到风电机组的寿命与安全。载荷测试可以让风电机组制造商与风电场运营商了解风力发电机组在不同的载荷工况下各个部件的结构响应情况。基于IEC 61400-13标准,介绍了一种风力发电机组载荷测试方法,并给出了部分测试结果。测试结果表明,该测试方法的精度可以满足相关标准的要求。
In recent years, wind turbine tower buckling and blade broken often happened. Heavy load and insufficient fatigue strength of wind turbine should be the main reasons. To prevent this case, load measurement of the wind turbine is necessary. The wind turbine load measurement is one of the type tests of wind turbine. The load of each wind turbine component will affect the safety and life span of the wind turbine. The wind turbine load measurement can help the wind turbine manufacturer and wind farm operator to know the structural response of the wind turbine components with different load cases. According to the IEC 61400-13 standard, a method of the wind turbine load measurement is introduced and some measurement results are given. The results indicate that the accuracy of this measurement method can fulfill the requirements of the related standards.
