Embodiment 2

[0104] This embodiment provides a method for detecting the degree of disturbance of a wind turbine tower, and the detection method is further improved on the basis of Embodiment 1.

[0106] Step S10: performing low-pass filtering on the accelerations collected by the two acceleration sensors respectively, and the frequency of the low-pass filtering is 10 Hz-100 Hz;

[0107] Step S11: Calculating the disturbance displacement respectively according to the respective accelerations of the two acceleration sensors after low-pass filtering.

[0108] Since the shaking of the wind turbine tower is mainly a low-frequency signal, it is also a low-frequency signal that needs to be analyzed. Here, the low-pass filter can filter out high-frequency interference signals and high-frequency signals that do not need to be analyzed to improve data accuracy.

Abstract

The invention discloses a detection method, system, medium and electronic equipment for the degree of disturbance of a fan tower. Two acceleration sensors are arranged on the top of the fan tower. The detection method includes: obtaining the accelerations collected by the two acceleration sensors respectively; using the accelerations collected by the two acceleration sensors respectively to calculate the respective disturbance displacements corresponding to each of the acceleration sensors; using the two acceleration sensors The respective disturbance displacements are used to calculate the disturbance degree of the wind turbine tower. The technical solution of the present invention uses two acceleration sensors to detect the accelerations whose directions are perpendicular to each other, and performs digital signal processing on the acceleration data to accurately detect the turbulence of the fan tower. When the detected disturbance range is too large, control commands can be generated to adjust the operating status of the fan in time to ensure the safe operation of the entire fan system.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a detection method, system, medium and electronic equipment for the disturbance degree of a wind turbine tower. Background technique [0002] As a new energy source with the advantages of being clean, renewable and not damaging the geographical environment, wind power has attracted more and more attention from researchers and enterprises. The wind turbine tower is an important part of the wind power generation system, so the monitoring of the disturbance degree (also called dynamic disturbance) of the wind power generation system is related to the safe operation of the wind power generation system. [0003] In the prior art, an acceleration sensor is usually used to directly measure the acceleration value of the tower disturbance, and an inclination sensor is used to measure the inclination to jointly judge the disturbance degree of the tower. However, since the di...
