TECHNICAL FIELD

[0001] The application belongs to the technical field of offshore wind power and photovoltaic technology, and particularly relates to a shared mooring double-impeller floating wind turbine and photovoltaic integrated power plant. BACKGROUND

[0002] With the accelerated transformation of global energy structure, the limitations of land-based renewable energy gradually emerge. Concentrated wind and solar power stations are limited by land resource shortage and ecological red line constraints, and the difficulty of project site selection increases sharply. The development of clean energy such as wind and solar energy on land is gradually approaching saturation, and the development space is limited. Under this background, the ocean, which accounts for 71% of the earth's surface, is becoming a strategic place for new energy, and the super large wind energy field and all-weather photovoltaic potential in its deep water area are particularly eye-catching. Floating wind turbines and photovoltaics, two emerging forms of ocean energy development, have become a popular research direction. They can operate in deep sea areas and have broad application prospects. However, traditional floating wind turbines and photovoltaic platforms mostly use independent mooring systems, which not only increases the construction cost of wind and photovoltaic power plants, but also expands the use of sea area, causing resource waste.

[0003] Most traditional floating wind turbines are single-impeller systems, but in deep sea areas with better wind resources, single-impeller wind turbine systems have low efficiency in capturing wind resources. SUMMARY

[0004] The purpose of the present application is to provide a shared mooring double-impeller floating wind turbine and photovoltaic integrated power plant, to improve the utilization efficiency of wind and solar energy resources in deep sea areas, to reduce the overall power generation cost, and to improve energy utilization.

[0007] The floating wind turbine and photovoltaic integrated unit comprises a double-impeller wind turbine platform, three photovoltaic power generation platforms and a shared mooring anchor point, the wind turbine platform is connected to the three photovoltaic power generation platforms by two connecting cables, and the photovoltaic power generation platforms are distributed in a triangular shape around the double-impeller wind turbine platform.

[0008] The two connecting cables of adjacent floating wind turbine and photovoltaic integrated units are fixed on the shared mooring anchor point.

[0009] The double-impeller wind turbine platforms are connected by a cable.

[0010] Further, the wind turbine platform adopts a semi-submersible platform, including a central machine position column arranged in the center, the central machine position column is installed on a platform central column, three pontoon columns, horizontal water pressure plates are uniformly distributed and installed on the circumference of the platform central column, the pontoon columns are connected with the platform central column through horizontal water pressure plates and horizontal support rods, the pontoon columns are located on the upper part of the horizontal water pressure plates, and adjacent pontoon columns are connected through fixed support rods.

[0011] Further, the wind turbine platform system is a double impeller system.

[0012] Further, the double impeller system is connected symmetrically through support inclined columns, and the wind sweeping area is expanded.

[0013] Further, platform fairleads are arranged on the horizontal water pressure plates, and the platform fairleads lead wind turbine platform mooring lines.

[0014] Further, the photovoltaic power generation platform adopts a semi-submersible platform, including four pontoon support structures, photovoltaic platform assemblies are installed on the top of the pontoon support structures, heaving plates are installed on the pontoon support structures, and adjacent pontoon support structures are connected through connecting support rods.

[0015] Further, the photovoltaic power generation platform is connected with the wind turbine platform at two top points on the same side, and the other two top points are connected with the same set of shared mooring anchor points through respective cables.

[0016] Further, the pontoon support structure leads photovoltaic platform mooring lines.

[0017] Further, the shared mooring cable is arranged in the form of a catenary line, a tensioned line or a semi-tensioned line.

[0018] Further, the floating wind turbine photovoltaic array is arranged in a straight line.

[0019] The beneficial effects of the present application are:

[0020] The present application adopts the shared mooring integrated design of the floating wind turbine photovoltaic power plant, which is committed to reducing the system cost of the deep sea power plant, and improving the utilization rate and power generation capacity of marine resources. By integrating the floating wind turbine and the photovoltaic platform, the potential of marine space is fully developed, the complementation of wind power generation and solar power generation is realized, and the utilization efficiency of marine resources is optimized.

[0021] This invention integrates a floating wind turbine with photovoltaic power, enabling simultaneous wind and solar deployment and fully utilizing the complementary characteristics of wind and solar energy to improve energy efficiency. This integrated design allows for efficient utilization of wind and solar energy in various marine environments and weather conditions. Furthermore, through the complementarity of wind and solar power generation, the system enhances the sustainability and reliability of overall energy supply, ensuring stable power output under diverse conditions.

[0022] This invention employs a floating wind turbine and photovoltaic shared mooring system, which reduces the number of anchor chains compared to traditional single-mooring methods, thereby effectively lowering the cost of the power plant. This design also significantly reduces the occupation of marine space, improves the utilization rate of the ocean area, and is of great significance for the efficient use of marine resources and environmental protection.

[0023] This invention improves the positioning performance of the mooring system by optimizing the mooring structure and anchoring method. The shared mooring system allows the floating wind turbine and photovoltaic platform to mutually constrain each other, thereby reducing the platform's motion response. Simultaneously, the shared mooring system exhibits excellent structural stability, ensuring good safety even if any mooring cable breaks unexpectedly. This design meets the positioning requirements of floating platforms in complex marine environments, ensuring the stability and safety of the power plant under harsh sea conditions.

[0024] This invention employs a dual-rotor wind turbine instead of a traditional single-rotor wind turbine, significantly improving the efficiency of capturing deep-sea wind resources and increasing energy conversion rates. Furthermore, compared to single-unit wind turbines, multi-unit turbines offer advantages in deploying smaller blades at sea, cheaper operation, less installation, and shared floating platform access. Co-locating dual-rotor wind turbines with photovoltaic platforms can greatly improve energy utilization and power generation efficiency.

[0025] This invention organically combines floating wind farms and photovoltaic power plants by sharing a single mooring system, enabling the co-deployment of floating wind and solar power. It represents an improvement over traditional single-system mooring methods. The system utilizes a series of mooring chains and anchoring foundations to organically and rationally connect the wind turbines and photovoltaic platforms, significantly improving the safety and stability of the entire mooring system under harsh sea conditions. This design not only reduces the system cost of deep-sea wind and solar power plants but also effectively reduces the sea area used, improves power generation efficiency, achieves efficient utilization of renewable energy, and supports the flexible deployment of wind and solar power plants in deep-sea areas.
