Wind turbine generator fault diagnosis and processing method and system

Abstract

The invention discloses a wind turbine generator fault diagnosis and processing method and system, and the system comprises a data analysis module, the input end of the data analysis module is connected with a wind turbine generator, and the output end of the data analysis module is connected with a terminal through a database. The method comprises the steps: establishing a troubleshooting guidance library according to historical fault occurrence conditions and processing experience; establishing a logic diagnosis library according to the relationship between the trigger condition of the windturbine generator fault code and the I / O point data; establishing an expert information module and associating the expert information module with the processing guidance scheme; setting evaluation information in the diagnosis analysis report and the processing guidance scheme, and evaluating and adjusting the scheme by field personnel. According to the technical scheme, the method directly faces the whole process of field fault processing business, guides and supports the whole process of fault occurrence, fault analysis and fault solution, pushes a troubleshooting guidance scheme immediatelywhen a fault occurs, carries out troubleshooting on purpose, locates the fault accurately, provides a processing guidance scheme, and effectively solves the fault.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a method and system for fault diagnosis and processing of a wind turbine. Background technique [0002] In recent years, the operation and management of wind turbines has faced enormous challenges. There are various models of wind turbines, as well as various components and control systems. The log files generated by software systems such as the main control system, pitch system, and converters are Professional tools need to be used to download and view, and the analysis process is complicated, requiring personnel with strong technical ability and data analysis experience. However, wind farms are often located in remote areas, with harsh natural environments, difficult staffing and frequent replacement, and insufficient experience in handling personnel. The response is not timely in the fault occurrence stage, the fault location is not accurate in the fault analysis stage, an...
