Simulation of Online Monitoring Method for Partial Discharge at High-Voltage Power Cable Terminals
With the rapid development of power transmission technology,the application of high-voltage power ca-bles is becoming increasingly common,and the demand for online monitoring of partial discharge behavior of high-voltage power cable terminals is also growing.In order to solve the problems of poor effectiveness and low accuracy of current monitoring algorithms,this paper proposes an online gray discrimination monitoring algorithm based on condi-tion generation network.Firstly,the infrared camera was used to collect the features of the power cable terminal,and then the gray photos were averaged to remove the background noise;Then,based on k-means algorithm,the partial discharge position was located to determine whether there was discharge at the cable terminal;Finally,the condition generation network was used to optimize the discharge judgment steps,and the temperature discrimination method was used to judge the discharge degree,so as to improve the accuracy of discharge monitoring.The experimental results show that the accuracy of the proposed algorithm in partial discharge monitoring is improved by at least 5%,which im-proves the monitoring accuracy and reduces the harm of partial discharge to power transmission.
