基于MEEMD与TEO的电缆故障测距方法
A Power Cable Fault Location Method Based on MEEMD and TEO
摘要
Abstract
Correct identification of fault line wave head and accurate double-terminal traveling wave distance measuring ensure the accuracy of cable fault travel wave distance measurement.In order to solve the problem of modal aliasing in the empirical mode decomposition (EMD) in Hilbert Huang transform (HHT) , a new method based on modified ensemble empirical mode decomposition (MEEMD) and Teager energy operator is proposed for the traveling wave fault location.The problem of the influence of the fault traveling wave velocity and the actual length of the line on double-terminal traveling wave distance measuring accuracy, double-terminal traveling wave distance measure is proposed which is not affected by wave velocity.The effectiveness and high precision of the proposed method are demonstrated by PSCAD/EMTDC simulation results.关键词
