Embodiment 1

[0030] Figure 3A A flow chart of a method for monitoring the infrastructure of wind power generation equipment according to an embodiment of the present invention is shown. Such as Figure 3A As shown, the method includes the following steps:

[0031] S101: Obtain a wind rose diagram of the wind power generation equipment.

[0032] S102: Determine the location where the wind power generation equipment is located with the most abundant wind resources according to the wind rose diagram.

[0033] The wind rose diagram in the present application can be the commonly understood "wind direction frequency rose diagram" (also referred to as "wind direction rose diagram", "wind direction diagram"), or it can be a wind speed rose diagram, or a wind energy rose diagram.

[0034] The wind direction frequency rose diagram can reflect the percentage of the number of occurrences of various wind directions in all observations within a certain period of time; for example Figure 3B The great...

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.
