A wind field simulation device in southern mountainous areas

Abstract

The invention discloses a wind field simulation device in the southern mountainous area, which is used to form a wind field around the wind power equipment to be tested, including an air supply assembly arranged around the wind power equipment to be tested and a control system for controlling the air supply assembly; The air supply assembly includes at least two groups of air supply outlets, and each group of air supply outlets is arranged perpendicular to each other; the control system includes a wind pressure control module and a wind direction control module, which are used to control the wind pressure and wind direction of the air supply outlets respectively. The wind field simulation device in the southern mountainous area of ​​the present invention has the advantages of being simple and practical, the simulation effect is complex and changeable, and can provide test conditions for the development of wind power equipment in the southern mountainous area.

Description

technical field [0001] The invention relates to the field of wind power equipment test devices, in particular to a wind field simulation device in southern mountainous areas. Background technique [0002] The existing wind power equipment design technology is still immature, and a large number of experimental studies are needed to improve and revise the design scheme. In recent years, the installed capacity of wind power equipment in the mountainous areas of southern my country has grown rapidly, but at the same time it also shows the phenomenon of "acclimatization". This is mainly because most of the existing wind power equipment is designed according to the single wind direction and wind condition in the plain area, and the simulated wind direction of the test equipment is also relatively single. , gust, gradual wind and random wind and other wind components. The wind power equipment developed based on the design experience of wind conditions in plain areas is difficult ...

AI Technical Summary

Problems solved by technology

This is mainly because most of the existing wind power equipment is designed according to the single wind direction and wind condition in the plain area, and the simulated wind direction of the test equipment is also relatively single. , gust wind, gradient wind and random wind and other wind components

The wind power equipment developed based on the design experience of wind conditions in plain areas is difficult to fully adapt to the environment in southern mountainous areas, and the performance generally fails to meet the expected results in actual use.
