Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind-solar power generation, and in particular to an offshore wind-solar power generation device. Background Art

[0002] Land photovoltaic: refers to photovoltaic power generation systems used in land areas. Conventional photovoltaic modules are generally used as photoelectric conversion equipment; steel columns and steel purlins are used as support frames, fixed to the frame of the photovoltaic modules at 4 or 8 points, so that the photovoltaic modules have a certain southward inclination angle to maintain the best solar incidence angle, and have a certain windproof strength and rigidity to avoid the cells in the middle of the photovoltaic modules from deforming due to external forces and causing hidden cracks.

[0003] Water photovoltaic: refers to a system that uses a floating body to float photovoltaic modules on the water surface to generate electricity. The main difference between a water photovoltaic power station and a land photovoltaic power station is that a floating body and an anchoring system are used instead of the ground piles and brackets of land photovoltaics to provide support for photovoltaic modules. The back-end junction box, inverter equipment, transformer, and collection line are the same or similar to the land photovoltaic system. In the photovoltaic power generation system, the part from photovoltaic modules to photovoltaic inverters is photovoltaic-specific equipment. In the wind power system, the part from wind turbines to converters is wind-specific equipment. The output ends of photovoltaic inverters and wind power converters are connected to the box-type transformer together, that is, starting from the box-type transformer, including the collection cable, submarine cable, offshore substation to the transmission line, onshore centralized control center, and all equipment and facilities of the grid access part are shared.

[0004] As floating photovoltaics use anchoring components to fix photovoltaics to the seabed, due to long-term use, the steel cables of the anchoring components are often easily entangled with aquatic plants. At the same time, as the sea water rises and falls, the steel cables cannot tighten the photovoltaics to the seabed.
