Wind generating device used for sea floating wind machine pool model test

Abstract

A wind generating device used for a sea floating wind machine pool model test comprises a base, an overall rectifying device and a plurality of wind generating and rectifying units which are arrayed tightly in parallel and connected, wherein the base is of a square frame structure and provided with a wind inlet and a wind outlet; the overall rectifying device is installed in the position, on the wind outlet, of the square frame, and the cross section of the square frame is full of the overall rectifying device, so that a wind field is rectified; the wind generating and rectifying units are connected in the position, on the wind inlet, of the square frame, each wind generating and rectifying unit comprises a wind generating unit, a connector for transforming round into square and a wind generating unit rectifying device, each wind generating unit is used for generating an original round wind field, each connector for transforming round into square is of the structure for transforming round to square and used for transforming the generated round wind field into a square wind field, the round end of each connector is close to the wind inlet and connected to the corresponding wind generating unit, and the square end of each connector is close to the wind outlet, and each wind generating unit rectifying device is installed in the corresponding square end and used for rectifying the corresponding original wind field. The round wind fields are transformed into the square wind fields, the gap between every two adjacent wind fields is eliminated, the original wind fields are effectively rectified two times, and therefore precision of the generated wind fields is improved.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and relates to a novel wind-making device for testing, in particular to a wind-making device for model testing of a floating wind turbine pool on the sea. Background technique [0002] Wind energy is currently the fastest growing renewable energy with the greatest potential. The world’s available wind energy resources are very abundant. Resources are concentrated in deep water areas offshore. The wind energy resources of major offshore wind energy countries such as the United States, China, Japan, and Norway are all concentrated in non-shallow water areas with water depths exceeding 30m. As a new equipment to replace traditional fixed wind turbines, deep-water floating wind turbines have broad application prospects and have become a hot field of offshore wind energy research abroad. [0003] The floating wind turbine is mainly composed of three parts, namely the wind turbine at the t...

AI Technical Summary

Problems solved by technology

The wind-generating device in the pool model test adopts a structure formed by simply accumulating multiple groups of traditional circular wind-generating units, which cannot meet the high-precision wind-generating requirements

The wind generation device has the following problems: 1) There are gaps between adjacent circular wind generation units, and a uniform wind field in the plane cannot be generated; 2) The wind field generated by the traditional circular wind generation unit has redundant circumferential velocities
