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...
