Abstract

The present application provides a fault diagnosis method and device for a yaw system in a wind power generator set, which relate to the technical field of wind power generators. Among them, the method obtains the monitoring data collected in the yaw system, inputs the monitoring data into the yaw fault diagnosis model, and outputs the fault diagnosis result, wherein, the fault diagnosis model is obtained by training the known fault diagnosis results and the corresponding monitoring data, and the fault Diagnosis results include at least one of the following: yaw sensor position offset, yaw sensor damage, yaw contactor adhesion, yaw motor / reducer hardware damage, yaw motor brake failure, so that during work, the The monitoring data collected by the yaw system is input into the yaw fault diagnosis model in real time, and the yaw fault diagnosis model is used to determine whether the yaw system is faulty and the specific fault diagnosis results when a fault occurs. In this way, the operation and maintenance personnel can avoid going to the plane Carry out troubleshooting to improve the efficiency of fault diagnosis of the yaw system.

Description

technical field [0001] The present application relates to the technical field of wind power generators, in particular to a fault diagnosis method and device for a yaw system in a wind power generator. Background technique [0002] Wind power generators use wind energy to generate electricity, which is a device that converts wind energy into mechanical energy and then into electrical energy. Areas with better resources, for example, remote mountain villages and islands. [0003] The yaw system is an important part of the wind turbine. When the direction of the wind speed vector changes, it can quickly and smoothly align the wind direction so that the wind rotor can obtain the maximum wind energy. However, when it fails, operation and maintenance personnel need to go to the machine bit to check. [0004] Therefore, the existing fault detection method for the yaw system has the problem of low fault diagnosis efficiency. Contents of the invention [0005] The purpose of the...
