Problems solved by technology

[0004] There are two major deficiencies in the existing floating platforms: 1) high construction and maintenance costs, which are not convenient for large-scale application in offshore wind farms; 2) slow response to instantaneous changes in wind and wave loads, not only poor motion stability, but also There is also a huge hidden danger of insufficient survivability under extreme sea conditions

Abstract

The invention discloses a novel offshore wind turbine floating type platform. The novel offshore wind turbine floating type platform comprises blades, a cabin, a tower frame, a floating type foundation, a stabilizer frame and motion stabilizers; the blades, the cabin and the tower frame are mounted on the central position of the floating type foundation, the four motion stabilizers are evenly distributed at the bottom of the floating type foundation in the circumference direction through the stabilizer frame, through external loads borne by the bottom of the floating type foundation, damping of the motion stabilizers is adjusted, and the aim of improving the stability of the floating type structure is achieved. The speed of responding to wind-wave load instantaneous variations in the different circumference directions is high, the main device is simple in type, good controllability and maneuverability are achieved, and mounting and maintaining are facilitated.

Description

technical field [0001] The invention belongs to the field of renewable clean energy and marine equipment, and relates to a novel offshore wind-powered floating platform. Background technique [0002] Wind power is an efficient and clean energy with the largest development scale among many renewable energy sources and the most capable in terms of economic benefits, which can be compared with traditional fossil energy. Compared with onshore wind energy resources, offshore wind energy resources are more abundant and stable, and have many significant advantages such as low wind shear, low turbulence, no land use restrictions, no visual impact and noise interference, etc. Therefore, in recent years, the development of offshore wind power has It has attracted great attention worldwide. However, the high degree of uncertainty in the marine environment and offshore climate has also brought great challenges to the development of offshore wind power projects. In order to control ris...
