随着海上浮式风电技术的发展，我国大功率漂浮式海上风力机组开始走向工程示范应用。由于风机厂商对上部风机结构参数的保密，针对实际工程项目中的漂浮式风力机进行数值仿真分析具有诸多挑战和难度。本文以实际工程项目为例，研究漂浮式海上风力机在数值仿真过程中的关键技术。通过建立等效推力模型等手段，实现工程样机的数值建模并进行典型工况的动力响应分析。基于本文的研究成果可以有效解决实际工程项目中浮式风力机数值模型建立的难点，对促进我国风电产业技术发展，加速我国海上风电商业化进程具有重要意义。

With the development of floating offshore wind turbine technology, engineering projects of large scale floating offshore wind turbine has begun to emerge. Because manufacturers keep the parameters of wind turbine confidential, there are many challenges in numerical simulation analysis of floating offshore wind turbines in practical engineering projects. In this paper, the key technologies on numerical simulation of floating wind turbine in the practical engineering project was studied. Through the equivalent thrust model, a numerical model of real floating wind turbine was established and the dynamics responses under a typical load case was analyzed. Based on the research results of this study, the difficulties in establishing the numerical model of floating wind turbine in practical engineering projects can be well solved. This is of great significance to promote the technical development and accelerate the commercialization of China's floating wind turbine industry.
