The invention relates to artificial intelligence and motor technology, and provides a wind turbine generator fault monitoring method and device, and the method comprises the steps: determining a brake disc fault recognition result based on a current first monitoring picture of a brake disc in a wind turbine generator and a first picture feature library; determining a hydraulic oil level fault identification result based on the hydraulic oil level parameter of the wind turbine generator and a preset hydraulic oil level threshold value, and determining a yaw system fault identification result based on a current second monitoring picture corresponding to a yaw speed reducer in the wind turbine generator and a second picture feature library, and finally, based on the brake disc fault identification result, the hydraulic oil level fault identification result and the yaw system fault identification result, determining a wind turbine generator fault identification result. The core components and the core working parameters of the wind turbine generator can be monitored in real time and remotely in time, fault judgment is carried out in time based on the core components and the core working parameters of the wind turbine generator, the fault condition of the wind turbine generator can be detected rapidly, and the fault maintenance efficiency of the wind turbine generator is improved.
Description
technical field [0001] The present application relates to the technical field of electric motors, and in particular, to a fault monitoring method and device for a wind turbine. Background technique [0002] The wind turbine (that is, the wind turbine) includes a wind wheel and a generator; the wind wheel contains blades, hubs, reinforcements, etc.; it has the functions of blades being rotated by wind to generate electricity, and the rotation of the generator head. The wind power source is composed of a wind turbine generator set, a tower supporting the generator set, a battery charging controller, an inverter, an unloader, a grid-connected controller, and a battery pack. [0003] The cost of wind turbines is generally high. Once a fault occurs, if it is not repaired in time, it will lead to high cost losses. At present, the commonly used maintenance methods for wind turbines are planned maintenance and post-event maintenance. Scheduled maintenance refers to routine mainten...
