Automatic Detection Method for Stability of Relay Protection Devices Based on LM Algorithm
In order to improve the stability detection effect of relay protection devices,an automatic detection method for relay protection device stability based on LM algorithm is proposed.This method first collects data and preprocesses it using local anomaly factors to improve data quality.Secondly,select the Weibull distribution function as the basic function of the aging failure model,take its derivative,obtain the corresponding failure density function,and construct the aging failure model of the relay protection device.Finally,the LM algorithm is used to estimate the key parameters of the model to improve the accuracy of detection,and the updated parameters are input into the aging failure model to achieve automated detection of relay protection device stability.The results show that the proposed method has high detection accuracy,high detection efficiency,and can effectively achieve stability detection of relay protection devices.
