The deep and remote sea wind power generation has great potential as a new hot spot for the research of renewable energy sources, because the wind speed is more uniform due to the fact that the sea surface roughness is lower than that of the land surface compared with the land wind power generation; secondly, the wind speed of the deep and distant sea is higher, so that more wind energy can be obtained, and finally, the influence on the environment is small, and the available wind power field is more. For a floating wind power plant, the whole plant comprises: the system comprises a wind turbine generator, a floating platform, a mooring system and an anchoring system. The floating platform is the most important component, and the most important characteristic of the floating platform is that the floating platform has 6 degrees of freedom movement, and the impact load of the environment is large, such as sea waves, wind, ice and ocean current, which can cause fatigue failure of the platform. In order to ensure the reliability and the safety of the offshore floating platform, it is of great significance to explore the offshore platform design with high stability and small power transmission amplitude.
The main scale of the floating wind power platform is usually determined by demonstration and analysis from a plurality of overall directions such as stability, motion performance and the like, the platform usually performs power generation operation under appointed draft, the existing offshore wind power platform adjusts the draft of the platform by changing the water quantity inside a ballast tank, thereby adjusting the stability of the platform, and coping with sea waves at sea, the impact of wind and ocean currents on the platform, because the sea waves and sea wind change rapidly, the response speed of water inflow from the outside is slow, the requirement of the platform for rapid and stable operation cannot be met, and when the existing platform carries out ballast for keeping stability, the draft of the platform is inevitably increased along with the increase of the draft of the platform, so that the floating wind power platform is not suitable for a water area with the requirement on the water depth, and the application range is narrow.

The movement of the platform can be effectively reduced through the conical buoy 1, so that the platform is more stable, and the restoring moment is increased.
Referring also to fig. 2, the cross-section of the transition section 2 is smaller than the cross-section of the pontoon 1 at any height.
