Problems solved by technology

[0005] The embodiment of the present invention provides a shallow water floating wind power system and its dynamic cable assembly to solve the problem that when the sea conditions are relatively bad, the existing dynamic cable will drift in a large range under the action of waves and ocean currents, and the dynamic cable will drift in a large range. After drifting, it is easy to collide with the floating wind turbine or the anchor chain of the floating wind turbine and cause failure

Embodiment 2

[0073] This embodiment also provides a floating wind power system in shallow water, including a floating wind turbine, a static cable, and the dynamic cable assembly in the first embodiment.

[0074]The floating fan floats on the sea surface. Exemplarily, the floating fan includes a fan, a central tower and a floating platform, wherein the fan can be a three-blade fan, and the fan is installed on the top of the central tower, and the bottom of the central tower The terminal is arranged on a floating platform, and the floating platform can be a Spar (single-column type), a barge or a semi-submersible platform, etc., and this embodiment is not limited here. The static cable is fixed to the seabed, for example, the static cable may be fastened to the surface of the seabed by fasteners. One end of the dynamic cable in the dynamic cable assembly is electrically connected to the floating wind turbine, for example, one end of the dynamic cable can be suspended on the floating platfor...

Abstract

The embodiment of the invention provides a shallow water floating type wind power system and a dynamic cable assembly thereof. The dynamic cable assembly for the shallow water floating type wind power system comprises a dynamic cable, a plurality of buoyancy units and a plurality of connecting units; each connecting unit comprises a mooring chain and an elastic cable; the dynamic cable is connected with a seabed through the mooring chains and the elastic cables; the connecting units and the buoyancy units jointly define the line type of the dynamic cable; the line type of the dynamic cable comprises a first wave trough section, a plurality of wave crest sections and second wave trough sections between every two adjacent wave crest sections; the buoyancy units are arranged at the top ends of the wave crest sections; and the connecting units are arranged on the sides, away from a floating type draught fan, of the wave crest sections. According to the dynamic cable assembly for the shallow water floating type wind power system, when the sea condition is severe, the dynamic cable cannot drift in a large range, when the impact borne by the dynamic cable is too large, the elastic cables can reduce the impact load borne by the dynamic cable, and the situation that the joint between the dynamic cable and the mooring chains is damaged due to too large impact is avoided.

Description

technical field [0001] Embodiments of the present invention relate to offshore wind power generation technology, in particular to a floating wind power system in shallow water and a dynamic cable assembly thereof. Background technique [0002] With the development and application of new energy, the application of floating wind power systems has become an inevitable trend to obtain high-quality wind resources and reduce construction costs. At present, floating wind power systems are mainly used in shallow waters with a water depth of less than 60m. A floating wind power system includes a floating wind turbine, a dynamic cable and a static cable. One end of the dynamic cable is connected to the floating wind turbine and the other end is connected to the static cable. That is, the power generated by the floating wind turbine can be transmitted through the dynamic cable and the static cable. [0003] At present, the line type of the dynamic cable mainly presses the dynamic cable...
