Three-stand-column type offshore wind power generation platform system

Abstract

The invention discloses a three-stand-column type offshore wind power generation platform system which comprises a draught fan system, a floating foundation and a mooring system, the draught fan system comprises a draught fan tower, and the draught fan tower stands in the center of the upper portion of the floating foundation; the floating foundation comprises three stand columns and a center disc, the three stand columns are distributed in an equilateral triangle shape, the center disc is arranged in the centers of the three stand columns, the center disc is connected with the upper portion of each stand column through an upper box type structure, and the lower portions of the stand columns are connected with one another through bottom buoyancy tanks to form a stable equilateral triangleshape. The floating foundation operation is shallow in draught and wide in water depth application range, can be applied to wide sea areas of 40 m or above, meets the performance of stability, movement, structure and the like by changing the size and span of structural components under the condition of guaranteeing shallow draught, is suitable for supporting offshore wind turbines with various powers, and is expanded to 10 MW and higher-power offshore wind turbine types.

Description

technical field [0001] The invention belongs to the field of marine floating wind power generation, and in particular relates to a three-column offshore floating wind power platform system. Background technique [0002] As a widely distributed renewable energy, offshore wind energy has been transformed from demonstration application to practical and commercialization. Internationally, prototype demonstration projects of floating wind power platforms have been established (Hywind demonstration project in Norway, Windfloat demonstration project in Portugal, Ideol demonstration project in France, etc.). Domestically, China's offshore shallow waters (Fujian, Guangdong and other provinces) have begun large-scale construction of wind power platforms with fixed offshore infrastructure. At present, there is no demonstration prototype of floating wind power platform in China, but the water depth of some sea areas where wind farms are planned to be built has reached more than 50m, an...

AI Technical Summary

Problems solved by technology

This kind of structure has a shallow draft, so the applicable water depth range is shallower, but because the main structure is located near the water surface, the motion response performance is not good, and the wave load is also relatively large

In addition, the chain stopper is installed above the water surface, and part of the anchor chain is arranged in the splash zone, which also reduces the fatigue performance of this part of the anchor chain
