Fault diagnosis method and equipment of wind turbine generator set

Abstract

The invention provides a fault diagnosis method and fault diagnosis equipment of a wind turbine generator set. The fault diagnosis method comprises the steps of: determining a system structure of a functional system to be diagnosed of the wind turbine generator set; determining components to be monitored among components of the system structure; establishing a fault and test correlation matrix model according to information flow directions among the components to be monitored in the system structure; determining a test point for fault detection of the functional system to be diagnosed according to the fault and test correlation matrix model; and detecting a test signal of the test point for fault detection, and determining a fault of the functional system to be diagnosed according to the detected test signal. According to the fault diagnosis method and the fault diagnosis equipment of the wind turbine generator set, the test point for fault detection can be determined according to thefault and test correlation matrix model, and the fault of the functional system to be diagnosed can be determined quickly through detecting the test signal of the test point for fault detection.

Description

Technical field [0001] The invention relates to the technical field of wind power generation. More specifically, it relates to a fault diagnosis method and equipment for a wind power generating set. Background technique [0002] As a kind of clean and renewable energy, wind energy is receiving more and more attention. The installed capacity of wind turbines is increasing year by year, and the proportion of wind power is increasing. Wind energy has gradually become a conventional energy source. With the increase in the number of wind power generators and the increase in the cumulative time of use, the failure rate of the wind power generators themselves increases accordingly, and these faults are distributed among the various functional systems in the unit. The occurrence of a fault will produce a series of safe actions. Therefore, improving the efficiency of judging unit faults and quickly troubleshooting hidden dangers directly determines the utilization rate of the unit, and ...
