Wind generating set fault diagnosis system and method

Abstract

The invention provides a wind generating set fault diagnosis system and method, and relates to the field of wind power generation. The wind generating set fault diagnosis system comprises a database subsystem and a self-diagnosis subsystem, wherein the database subsystem comprises a preset fault diagnosis model library and a preset fault solution database; the self-diagnosis subsystem is used forobtaining a fault file of a wind generating set, searching a target fault diagnosis model and outputting a diagnosis result according to the wind power variable parameter value in the fault file, thetarget fault diagnosis model and the fault diagnosis model corresponding to the fault identifier, wherein the fault file comprises a master control version information, a fault identifier and a wind power variable parameter value, the target fault diagnosis model is a fault diagnosis model corresponding to the master version information and the fault identifier in the fault file in the preset fault diagnosis model library, and the diagnosis result comprises a fault solution. By utilizing the system and method, the efficiency of fault diagnosis of the wind generating set can be improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a fault diagnosis system and method for a wind power generating set. Background technique [0002] Due to the shortage of resources, sustainable resources are applied in more and more fields. Such as converting sustainable resources such as wind energy and solar energy into electricity. In the field of wind power generation, wind energy is converted into electrical energy through a wind power generation system, and the converted electrical energy is transmitted to various devices that require electricity through the grid. [0003] With the development of wind turbine technology, the structure of the wind turbine control system is becoming more and more complex. Various faults may occur during the operation of wind turbines. In order to ensure the normal operation of the wind turbines, at present, the staff are on the site of the wind turbines, using fault data, combined wi...

AI Technical Summary

Problems solved by technology

However, the on-site staff often have insufficient experience in troubleshooting, and cannot combine the characteristics of the fault data with the solution well, resulting in a long time spent by the staff on troubleshooting the faults of the wind turbine, which leads to the failure of the wind turbine The efficiency of diagnosis is low
