Abstract
Advances in science and technology promote the use of more equipment in marine engineering. This equipment will undoubtedly increase energy consumption significantly. If only solar energy is used for charging, it may be able to charge in time to meet the demand when the sun is sufficient. In case of rainy weather, it will cause the navigation mark battery not to be charged in time, causing the equipment on the navigation mark to fail to work normally. For this reason, offshore wind power, as a renewable energy source, can make up for the lack of solar power for marine projects. In view of this research background, the paper studied the coherence effect between the blade and the tower wind field based on the wind turbine structure characteristics and the random wind power spectrum characteristics, and proposed the harmonic superposition method (HSMBTI) considering the interaction between the blades and the tower. This method is used to numerically simulate the random wind speed time history of the random wind field of the wind turbine structure, and check the calculated power spectrum and the target spectrum, which verifies the applicability of the HSM-BTI method to the random wind speed time history simulation of the wind turbine structure.
