Embodiment 1
[0034] figure 1 It shows a schematic flowchart of a method for detecting the working state of a wind power generating set provided by an embodiment of the present invention, and the steps of the method can be executed in a device for detecting the working state of a wind generating set.
[0035] Such as figure 1 As shown, the method for detecting the working state of the wind turbine includes:
[0036] In step S110, the load of the bolt is detected. When the wind turbine is initially installed, a bolt sensor is installed on the flange surface of the flange system to detect the load of the bolt in real time or at regular intervals. Bolt sensors can be installed for all the bolts on the flange surface, or only for some bolts on the flange surface. Preferably, the bolt sensors can be evenly distributed on the flange surface. For the type of bolt sensor, it can be specifically selected according to the stress form of the first component and the second component. When the first ...
Embodiment 2
[0041] figure 2 It shows a schematic flowchart of another method for detecting the working state of a wind power generating set provided by an embodiment of the present invention, which can be regarded as figure 1 A specific implementation manner of the shown method embodiment. Such as figure 2 shown, compared to figure 1 The method steps of the illustrated embodiment, figure 2 Specifically shows how to detect the load of the bolt; how to determine the working status of the first component and the second component. Such as figure 2 As shown, the method for detecting the working state of the wind power generating set includes the following steps:
[0042] For step S110, this embodiment specifically includes steps S210 and S220.
[0043] In step S210, the load of a single bolt is respectively detected, and the load amplitude of a single bolt is respectively acquired according to the single bolt load. In wind turbines, the load on a single bolt is constantly changing, ...
Embodiment 3
[0055] image 3 A schematic structural diagram of a device for detecting the working state of a wind power generating set provided by an embodiment of the present invention is shown. available for execution figure 1 The method steps of the shown embodiment, as image 3 As shown, the device for detecting the working state of the wind power generating set includes: a detection module 310 and a state determination module 320, wherein:
[0056] The detection module 310 is configured to detect the load of the bolt.
[0057] A state determining module 320, configured to determine the working states of the first component and the second component according to the mapping relationship between the bolt load and the load of the first component and the second component.
[0058] Optionally, the detection module 310 may include:
[0059] The detection sub-module 3110 is used for detecting a single bolt load respectively.
[0060] The calculation sub-module 3120 is used to obtain the ...
