The invention relates to the technical field of offshore wind power, in particular to a truss type offshore floating type wind power foundation platform which comprises a bottom frame, a wind turbine generator set, a floating type foundation and a three-dimensional truss structure, the three-dimensional truss structure comprises a truss body, floating boxes, a bottom box, a mooring turret and a mooring system, the floating boxes are fixed to two vertex angles of the bottom frame, and the bottom box is fixed to the bottom box. The mooring turret is fixedly connected to the other vertex angle, the bottom box is fixedly connected with the three vertex angles of the bottom frame, and the truss body is fixedly installed on the upper surface of the buoyancy tank. Large heave damping is formed through the floating type foundation and disturbance of surrounding seawater, fluctuation and swaying of the floating type foundation under the influence of environmental loads are restrained, a mooring system is arranged to passively and coaxially rotate around a mooring single point under the action of wind power, wind wheels of draught fans are kept to face the wind all the time, and by independently adjusting the output power of the two draught fans and the resistance of the wind wheels, the wind power generation efficiency is improved. The passive yaw function is actively intervened, and the maximum power generation efficiency is obtained through the maximum wind sweeping area.
本发明涉及海上风电的技术领域,尤其是一种桁架型海上漂浮式风电基础平台,包括底架、风电机组、漂浮式基础以及立体桁架结构,所述立体桁架结构包括桁架主体、浮箱、底箱、系泊转塔以及系泊系统,所述浮箱固定在底架其中两个顶角上,所述系泊转塔固定连接在另一个顶角上,所述底箱与所述底架三个顶角固定连接,所述桁架主体固定安装在所述浮箱上表面;本发明通过漂浮式基础,扰动周围海水构成较大升沉阻尼,抑制漂浮式基础在环境载荷影响下的起伏和摇荡,设置系泊系统受风力作用绕系泊单点被动同轴转动,保持风机风轮始终正面迎风,通过单独调整两台风机的输出功率与风轮阻力,主动干预被动偏航功能,以最大扫风面积获取最高发电效率。
