Problems solved by technology
However, as far as the existing fan systems are concerned, the above problems have not been well solved.
First of all, the wet surface area of the floating wind turbine foundation is not large, and the damping that can be provided is limited; thirdly, the restoring force and damping provided by the mooring system installed on the wind turbine foundation are insufficient, so that the top wind turbine foundation has a large range of motion, and these movements Seriously threaten the safety of the entire wind turbine system, in which the pitching motion in the direction of the leeward side greatly reduces the power generation efficiency of the wind turbine

Embodiment Construction
[0015] This embodiment provides a forward-leaning floating fan mooring system, the structure of which is as follows: Figure 1 to Figure 3 As shown, the whole system is composed of fan system and mooring system. The fan system includes a fan foundation 1, a floating body foundation 3, and a pitch plate 2 added on the periphery of the floating body foundation 3; the mooring system includes a tensioned mooring cable 4 and a tension tendon 6, both of which pass through the 5 is connected with the seabed 8 . A magneto-rheological damper 7 is connected between each tensioned mooring cable 4 and the suction anchor 5, and the top of the tension tendon 6 is connected to the front of the longitudinal centerline of the floating body foundation 3. The tops of the magneto-rheological dampers 7 are connected with electric wires 10 , and the electric wires 10 extend upward along the tensioned mooring cables 4 , pass through the foundation of the floating body and connect with the control s...

The invention discloses a forerake type floating fan mooring system which consists of a fan system and a mooring system. The fan system comprises a top fan base for power generation, a floating body base for supporting the whole fan base and a pitching plate connected to the floating body base, the mooring system comprises at least four tensioning mooring cables and a tension tendon, wherein the tensioning mooring cables and the tension tendon are injected into seabed through suction anchors, a viscous damper is connected between each of the tensioning mooring cables and the suction anchors, and the top end of the tension tendon is connected to the front of a longitudinal center line of the floating body base to enable the fan base to maintain a forerake posture. The forerake type floating fan mooring system is simple in structure, convenient and simple to mount, effectively improved in generating efficiency of a fan and improved in stability of the whole system.
Description
technical field [0001] The invention relates to a foundation mooring system for a floating wind turbine, which belongs to the field of marine floating wind power generators. Background technique [0002] With the depletion of non-renewable energy such as oil and natural gas and the gradual intensification of the "greenhouse effect", "green renewable energy" has attracted more and more attention from all countries in the world. As a typical representative of "green renewable energy", wind energy has developed particularly rapidly in recent years. Compared with land, offshore wind resources are more abundant, and the sea area is vast, not limited by land resources, so offshore wind power technology is a hot spot for research and application. [0003] Offshore wind turbines can be divided into fixed wind turbines (water depth below 50m) and floating wind turbines (water depth 50m-200m) according to the operating water depth. Fixed wind turbines are installed in offshore divin...
