摘要：

A dynamic simulation model was built for a large wind turbine, and 104 sets of simulation calculations were carried out under 18 cases. The sensitivity analysis of the aerodynamic and dynamic characteristics of the wind turbine was carried out, and the correlation between the load and the aerodynamic and dynamic characteristics of the wind turbine was given from the variation trend of load and operating state. According to the aerodynamic and dynamic characteristics of the wind turbine, the tower dynamic load identification model was built, and the model was embedded into the test wind turbine for real test verification. The results show that the dynamic identification load is in good agreement with the simulation results, and its mean deviation is about 5%. At the same time, through the verification of the prototype test, the test results show that the dynamic identification load and the measured results mean deviation of about 10%, with a high degree of coincidence. The established dynamic load model identification results are relatively stable. This method can provide support for the application of wind turbine towers, and can provide a convenient method for the safety monitoring of wind turbines. © 2020, Editorial Office of Journal of Vibration and Shock.
