Abstract
In this paper, a complete load test for a megawatt wind turbine is carried out, and a closed-loop design method containing simulation, load-test, model optimization and verification is proposed. Based on the test data, the frequency, damping, and pitch response of the wind turbine are identified to guide the optimization of simulation model. The verified results indicate that the trend of load results of optimized simulation model is same with that of measured data. The simulated frequency domain characteristics of the main components of the wind turbine are consistent well with those from measured data and meet the specification requirements. The proposed design method based on the load test can effectively improve the accuracy and reliability of the wind turbine simulation model.
