Abstract

The invention discloses methods and systems for diagnostic standard establishment and intelligent diagnosis of wind generation set oil monitoring. The method for diagnostic standard establishment comprises the steps that normality testing is carried out on oil test data, a calculating method for diagnostic standards is selected on the basis of results of normality testing, and the diagnostic standards are obtained through calculation. The method for intelligent diagnosis of wind generation set oil monitoring comprises the steps of establishing a diagnostic standard library according to the standard establishment method, extracting the diagnostic standards from the diagnostic standard library according to monitoring objects, and comparing the oil test data with the extracted diagnostic standards to judge whether the current oil test data belong to normal values, or attention values or alarming values. By means of the method and system for diagnostic standard establishment, accurate and objective diagnostic standards can be established, pertinence is high, accuracy is high, and an effective early-warning effect can be achieved; the method and system for intelligent diagnosis of wind generation set oil monitoring can greatly improve oil monitoring analytical judgment efficiency.

Description

technical field [0001] The invention relates to the technical field of monitoring of wind turbines, in particular to a method and system for establishing oil monitoring and diagnosis standards of wind turbines and an intelligent diagnosis. Background technique [0002] With the rapid development of my country's wind power industry, it is extremely important to improve the reliability of wind turbine operation. Condition monitoring of wind turbines is an important measure to improve the reliability of wind turbines. Among them, oil monitoring is one of the important contents of condition monitoring. [0003] The diagnostic criteria for oil monitoring are the basis for making diagnostic conclusions based on test data. The current oil monitoring and diagnosis standards generally use the national general oil change index, which is not targeted, and the diagnosis results are not accurate enough, which often leads to misjudgment. Since the deterioration of the oil in use depend...
