Load Measurement Method of the MW Class Wind Turbine
In recent years, wind turbine tower buckling and blade broken often happened. Large wind turbine load and insufficient fatigue strength 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 the wind turbine structure components will strongly 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 in this article. Meanwhile, the measurement results are given in this article. The results indicate that the accuracy of this measurement method can fulfill the requirements of the related standards.
