Abstract

The invention belongs to a blade unbalance fault monitoring method, and aims to solve the technical problems that a vibration sensor needs to be installed for collection of vibration signals during blade unbalance fault monitoring at present, and time and labor are consumed due to the fact that an existing blade balance monitoring method needs to carry out manual monitoring and manual adjustment on the basis of a large amount of manual labor. According to the wind turbine generator blade unbalance fault monitoring method based on the vehicle-mounted device, the vehicle-mounted device serves as a platform, vehicle-mounted automatic inspection and fan maintenance are achieved, the deep learning technology serves as basic technical support, and video data collected by the vehicle-mounted device are correspondingly monitored and processed. A wind turbine generator blade unbalance fault monitoring method is researched, adjustment parameters of a fan are analyzed and given, the parameters can be issued to a fan console, the balance angle of the blade is corrected, and intelligent operation and maintenance of a fan field are achieved. The vehicle-mounted device is used for carrying out itinerant monitoring on numerous fans, and the defect that a traditional manual monitoring method is time-consuming and labor-consuming is avoided.

Description

technical field [0001] The invention belongs to a blade imbalance fault monitoring method, in particular to a wind turbine blade imbalance fault monitoring method based on a vehicle-mounted device. Background technique [0002] Wind power is a renewable green energy that is being vigorously developed. It can effectively save water and coal resources, reduce air pollution, and has far-reaching significance for protecting the ecological environment. Wind farms are usually located in remote areas with poor technical and operating conditions. Therefore, the reliability and safety of wind power generation systems are of paramount importance. Blades are the key components for capturing wind energy in wind turbines, and their performance directly affects the overall performance of the wind turbine and the quality of power generation. [0003] Fan unbalance faults account for a relatively large proportion of all fan faults, and unbalance faults usually occur on blades or shafts. A...
