Abstract: With the rapid construction and deployment of offshore wind farms, large number of wind power related facilities such as wind turbines, substation platforms and power collection systems can generate electromagnetic interference to the surrounding environment during their operation. To mitigate the negative impacts of such interference, it is crucial to focus on the electromagnetic characteristics of wind turbines. Therefore, the analysis of electromagnetic scattering characteristics of offshore wind farms is focused on and the main methods currently used for this analysis are systematically reviewed. These methods include experimental measurement methods, high-frequency approximation methods (such as method of moments, physical optical method, physical diffraction method, geometrical optical approach and geometric diffraction method) and full-wave numerical methods (such as finite element method and time-domain finite-difference method). Through comparative analysis of the applicable characteristics of several methods and for improving the computing efficiency as well, it is proposed to introduce multipath effect analysis, expand the scope of model application and combine deep learning techniques, and it is also proposed that the future research direction should be to combine multiple methods to achieve more accurate electromagnetic characteristic analysis. All these can provide important references for the optimization of offshore wind farm deployment and the study of electromagnetic compatibility, thus facilitating the intelligent and sustainable development of offshore wind power technology.
