Abstract

Temperature is an important environmental load on offshore wind power systems. The harsh marine environment characterized by high temperatures and radiation, along with the slender and towering metal structure system, makes the temperature effects on offshore wind turbine support structures highly substantial and complex. However, the temperature load has not received sufficient attention and, in some cases, has been overlooked in the design and operation of wind turbine support structures. This paper focuses on the support tower structure of a wind power system, conducting finite element analysis and research on the temperature load of the support tower structure. First, the marine thermal environment of the wind turbine tower in service is analyzed to clarify the factors and mechanisms that affect the tower temperature. Secondly, based on the heat exchange and transfer process of the actual structure, a finite element calculation model for the temperature field of the wind turbine tower structure is established. Then, the finite element transient thermal analysis method is used to numerically calculate the temperature field of the wind turbine tower in service. Finally, the optimization of the finite element calculation model is carried out. The accurate finite element analysis of the temperature field of the wind turbine support tower structure is achieved, which provides the important theoretical foundation and technical support for the design of the wind turbine support structure considering the influence of the temperature effect, identification of the service state, and safety management of operation and maintenance.
