Abstract

The invention discloses a generator damage determination method and device, electronic equipment and a storage medium. Comprising the following steps: acquiring a tower drum vibration signal acquired by a data acquisition unit when a generator tower drum is in a vibration state; wherein the number of the data acquisition units is two or more than two, and each data acquisition unit is installed at a preset position of a generator tower; based on each tower drum vibration signal, determining a target signal relative entropy corresponding to each preset position; wherein the target signal relative entropy is used for reflecting the signal change degree in the transmission process of the tower drum vibration signal between the preset positions; and determining a target damage degree corresponding to the target signal relative entropy based on a pre-established corresponding relationship between the signal relative entropy and the damage degree. According to the technical scheme of the embodiment of the invention, manual detection is not needed, the detection cost is reduced, and the damage condition of the generator can be efficiently and safely determined.

Description

technical field [0001] The invention relates to the technical field of wind turbine damage monitoring, and in particular, to a generator damage determination method, device, electronic device and storage medium. Background technique [0002] Detecting the safety status of the wind turbine tower is an important measure to ensure the safety of wind power generation. At present, the inspection of the safety status of wind turbine towers mainly relies on manual inspection by staff, which is time-consuming and labor-intensive, resulting in high inspection costs; and the inspection period required for manual inspection is long, which is not conducive to the safety of wind turbine operation. Stability presents challenges. SUMMARY OF THE INVENTION [0003] The present invention provides a generator damage determination method, device, electronic device and storage medium, so as to achieve the purpose of efficiently and safely determining the generator damage. [0004] According ...
