Non-anchoring floating type large-megawatt wind power generation platform

Abstract

The invention provides a non-anchoring floating type large-megawatt wind power generation platform. The platform comprises a plurality of foundation floating type units, a fastening connecting mechanism, a plurality of wind power generation devices and a fixing structure, wherein the plurality of wind power generation devices are fixedly connected with the top end of a floating foundation, the plurality of foundation floating type units are fixedly connected with the fastening connecting mechanism, the fastening connecting mechanism is connected with the fixing structure, the fastening connecting mechanism freely rotates and floats up and down in the horizontal plane around the fixing structure, and the lower end of the fixing structure is fixed to the seabed. According to the non-anchoring floating type large-megawatt wind power generation platform, a positioning requirement needed by normal work of a wind turbine foundation is met, and the design problem of a traditional shallow water anchoring system is solved; a mooring mode only allows a rotation around a vertical axis of a fixed foundation, and a heaving movement of a floating type foundation, so that the undesirable effect of a coupling movement of a wind turbine foundation of floating type and a wind turbine in the prior art is avoided.

Description

technical field [0001] The invention belongs to the technical field of offshore floating wind power generation devices, in particular to a non-anchored floating large megawatt wind power generation platform. Background technique [0002] Wind energy is a clean and pollution-free renewable energy, which has the advantages of sustainability and inexhaustibility. Among all green energies, wind energy is the most mature and widely used green clean energy. my country's coastal wind energy resources are abundant, and it is very close to the economically developed power load center, and the return transmission distance is short, which is more favorable for grid connection and power consumption in the later stage. [0003] China has a long coastline, and areas rich in coastal wind energy resources are within 50km of the coast. The average water depth in this area is shallow, and the water depth in most areas is less than 60 meters. Therefore, the current development and construct...

AI Technical Summary

Problems solved by technology

Correspondingly, the grade and cost of anchoring equipment matching the design requirements, such as anchor chains and anchor piles, will be greatly increased, thereby increasing mooring costs

In addition, the tension mooring can be applied to more stringent geological conditions of the installation site, and the scope of application is small

For catenary mooring, also due to the limitation of water depth, the suspended length is relatively short

In order to meet the mooring requirements, the mooring radius needs to be increased, which increases the mooring cost. The most adverse effect is that the sea area occupied by a single floating wind turbine foundation will be very large, and the utilization rate of the wind field area will be greatly reduced.
