Method for monitoring running state of wind power generators

Abstract

The invention discloses a method for monitoring the running state of wind power generators. The method comprises the following steps that S1, each wind power generator is numbered, and monitoring datatransmission links are correspondingly established; S2, wind power information is acquired, and ideal operation state models of the wind power generators are generated in advance; S3, damping parameters are acquired so as to establish a damping parameter curve; S4, temperature parameters are acquired so as to establish a temperature parameter curve; S5, output current parameters are acquired so as to establish a current output curve; S6, an actual operation state model of each wind power generator is established; S7, the actual operation state model of each wind power generator is compared with the corresponding ideal operation state model, the wind power generator with the highest fitting degree is selected as the standard, transverse correction is carried out, and the running parametersof the wind power generators with deviation values exceeding a set threshold value are sifted out for labeling; and S8, deviation analysis is carried out according to the labeled parameters. During the application of the wind power generators, the single operation state of the wind power generators can be monitored, and the transverse parameter comparison and the group correction are carried out,so that the monitoring efficiency is improved.

Description

technical field [0001] The invention relates to wind power generator monitoring technology, in particular to a wind power generator operation state monitoring method. Background technique [0002] In the current wind turbine system, condition monitoring is becoming more and more important. Condition monitoring of wind turbines can avoid premature damage and shutdown, and optimize the maintenance plan of wind turbines. Existing monitoring methods for wind turbines monitor the operating status of wind turbines on an individual basis, which cannot be compared horizontally, and most of them focus on temperature and vibration monitoring, and the accuracy and efficiency of monitoring need to be improved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a method for monitoring the operating state of wind power generators. When it is applied, it can monitor the individual operating states of several wind power generator...
