Description
Technical Field
The application relates to the technical field of offshore wind power generation, in particular to a wind energy and solar wave energy combined power generation device based on a semi-submerged floating platform.
Background
Along with the transition of the offshore wind power layout of China from near shallow sea to deep open sea, the support structure form of the offshore wind power layout is also changed from fixed type to floating type. Currently floating platforms are mainly Spar, tension leg, semi-submersible and barge. The semi-submersible platform has the advantages of good stability, wide applicable water depth range, convenient construction and transportation, smaller draft, relatively lower investment cost and the like, and is expected to be the most widely applied structural form of the future offshore floating wind field.
The semi-submersible platform is generally composed of upright posts, cross beams, heave plates and mooring components, the upright posts are connected through the cross beams and inclined supports to form an integral platform, and the platform is fixed on a seabed through mooring chains. The column is typically divided into a plurality of compartments, and the bottom is typically fitted with heave plates of large diameter to slow down the heave motion of the foundation. When the foundation is in a floating state, the larger waterline area provides enough restoring moment for the system, so that the platform has good stability.
At present, a floating fan can only collect wind energy on a machine position to generate electricity, and considerable wave energy stored in deep open sea areas can not be captured and then utilized, so that the energy utilization rate of a platform is low. However, the sea conditions in deep sea areas are complex, the frequency of encountering extreme environmental conditions is far higher than that of offshore, when the wind speed of the environment is far higher than the allowable maximum value, the fan is locked, and no other power supply can supply power to the basic operation equipment of the platform; when the wave is too large, the whole inclination of the platform increases dramatically, so that the fan cannot normally generate electricity.
Meanwhile, the semi-submersible platform fan is arranged on one of the pontoons, the draft is shallow, the wave resistance is poor, the upper load is unevenly distributed under the condition of extreme stormy waves, and the pitching inclination angle of the semi-submersible platform fan can be controlled only by arranging an active ballast adjusting system, so that the power generation efficiency is ensured. The existing active ballast adjusting system has higher manufacturing cost, and the construction cost of the platform is increased.
