Method and system for monitoring foundation structure of wind power generation device

Abstract

The invention discloses a method and system for monitoring the foundation structure of a wind power generation device, wherein the method comprises the following steps of: acquiring a wind rose diagram of the wind power generation device, wherein the wind rose diagram comprises at least one of a wind direction frequency rose diagram, wind speed rose diagram or wind energy rose diagram; determininga direction with a most abundant wind resource of the position where the wind power generation device is located according to the wind rose diagram; arranging a displacement sensor at the bottom of atower barrel of the wind power generation device and in the direction with the most abundant wind resource in the circumferential direction of the tower barrel, wherein the displacement of the bottomof the tower barrel is monitored by the displacement sensor. According to the invention, the displacement sensor monitors the displacement of the bottom of the tower barrel, and the displacement sensor is arranged at the bottom of the tower barrel of the wind power generation device and can accurately reflect unstable conditions of the tower barrel caused by factors such as extrusion, abrasion and the like in the foundation structure; the displacement sensor is arranged in the direction with the most abundant wind resource in the circumferential direction of the tower barrel, the utilizationrate of the displacement sensor is higher, and less monitoring results can be generated.

Description

Technical field

[0001] The invention relates to the technical field of wind power generation equipment, in particular to a monitoring method and system for the basic structure of a wind power generation equipment. Background technique

[0002] With the continuous development of wind power technology, the application scale of wind power equipment is increasing. Wind power equipment includes wind power generators and fixed equipment. figure 1 The schematic diagram of the structure of the wind power generation equipment is shown. Such as figure 1 As shown, the wind power generation equipment mainly includes blade 01, hub 02, generator, tower 03, basic structure 04 and so on. Among them, the blade 01 and the hub 02 form a wind wheel, and the wind wheel rotates under the action of wind to drive the generator head to rotate to generate electric energy. The tower 03 is used to erect the wind turbine and generator in an open area with abundant wind energy resources. The basic structur...
