AI Technical Summary

Technical Problem

Existing technologies make it difficult to build a high-precision approximate aeroelastic model of an in-service wind turbine without the need for the original manufacturer's confidential model, resulting in insufficient accuracy in load and life assessment and a lack of effective digital simulation tools.

Method used

By selecting a preset basic model that matches the macroscopic parameters of the wind turbine under test, importing the technical parameters and geometric information from field testing and simulation analysis, calibrating the blade mass and stiffness distribution, and using the design power and thrust curves as a benchmark for overall calibration, a high-fidelity approximate aeroelastic model of the whole machine is constructed.

Benefits of technology

Without requiring original manufacturer confidential data, a high-fidelity approximate aeroelastic model of the entire machine with both structural dynamics and aerodynamic performance is constructed, providing a reliable digital simulation tool for load analysis, life assessment, and operational optimization.
