Description
Technical Field
The invention relates to the technical field of offshore power generation, in particular to a self-propelled offshore photovoltaic and wind energy coupling power generation floating platform.
Background
With the large-scale exploitation and combustion of fossil energy such as coal, petroleum and the like, social and environmental problems such as energy shortage, environmental pollution, greenhouse effect and the like are brought. Therefore, the development and utilization of renewable energy and green energy become important measures for realizing sustainable energy development and environmental protection in China. Renewable energy represented by wind energy and solar energy is developed rapidly; the areas available for development on land and offshore areas are gradually decreasing and the development is gradually limited, and people turn to direct their eyes to deep and open sea areas. The area has the advantages of few interference factors, stable wind power, good illumination condition and the like, and is the development trend of new energy industries in the future.
At present, the development of new offshore energy is mainly based on wind power, projects occupy large sea areas and are sparse in layout, and the maximum utilization of the sea areas of sites is not realized. On the other hand, the offshore wind farm constructed and operated at the present stage mostly adopts a fixed foundation, and is generally suitable for offshore water areas with the water depth of less than 50 meters. With the increase of the water depth, the installation cost of the fixed foundation is greatly increased, so that the economical efficiency of the offshore wind power project is reduced. And for deep and remote sea areas with water depths of hundreds of meters or even thousands of meters, the fixed foundation is no longer applicable. At the moment, the floating platform provides a more economic choice for developing wind energy resources in deep sea areas. Under the conditions that the unit capacity is larger and the offshore resources are less, the floating type wind turbine is the key direction for future development of offshore wind power.
It should be pointed out that, the existing floating wind turbine mostly adopts anchoring foundation to fix the platform in the working sea area, and the platform itself lacks power, resulting in its application scope becoming small, and is greatly limited by marine environment. In the service period of the wind turbine, if the wind turbine encounters the influence of severe ocean weather, the wind turbine is easy to damage in different degrees, and direct and indirect economic losses are caused. In addition, the existing offshore power generation facilities need numerous large-scale construction equipment for assistance in the transportation and field construction processes, relate to various construction processes, and have long period and high cost.

On the premise of not increasing the sea area, the generating capacity of unit area is improved, and the comprehensive economic benefit of the project is increased. In addition, offshore wind power and photovoltaic arrays can share one set of power transmission facilities, the generated power is transported uniformly, transformer substations do not need to be built and cables do not need to be added, and existing resources are utilized to the maximum extent.

The photovoltaic array is different from a traditional solar photovoltaic panel, and can freely rotate in a semi-infinite space. The electric drive universal ball joint is arranged between the photovoltaic panel and the lower supporting member, and the direction of the photovoltaic panel is adjusted in real time by means of the central control system, so that the azimuth angle and the inclination angle of the photovoltaic module with the best power generation efficiency under the current sunshine condition are obtained. The lower support structure of the photovoltaic array can be extended and retracted in a vertical direction to reduce shadowing effects between adjacent photovoltaic modules. When the sea stormy waves are large, the influence of wave sputtering on the photovoltaic assembly can be reduced by uniformly lifting the height of the photovoltaic array, so that the operation safety of the photovoltaic array power generation system is improved.
The invention is different from the traditional floating platform which is fixed in a specific sea area through an anchoring foundation and can not move freely, and the power positioning system is arranged on the platform, so that the autonomous navigation and power positioning functions of the platform can be realized. After the wind turbine and the photovoltaic array are prefabricated and assembled in the land or dry dock, the floating foundation sails to a designated sea area through a self-carried dynamic positioning system, and engineering ships such as tugboats or barges are not needed for hauling, so that the transportation cost is reduced. After the target location is reached, the dynamic positioning system is used for collecting the environmental loads (wind, wave and flow) of the target sea area in real time, the calculation is automatically carried out according to the direction provided by the position reference system, the thrust of each propeller is controlled, and the orientation and the position of the floating platform are kept relatively static. When the floating platform cannot resist environmental loads by means of the self structure in extreme weather, the platform is transferred to a safe sea area or returned to a nearby wind-sheltering port through a propeller of the dynamic positioning system. By arranging the dynamic positioning system on the floating basis, the flexibility of the platform can be obviously enhanced, the restriction of marine environment is eliminated, and the operation and maintenance safety of the platform during service is improved.
