Research for Fault Detection of Power Distribution Line Based on Hilbert-Huang Transform

Article Preview

Abstract:

Fault signal contains a large number of non-fundamental frequency transient signals when distribution line fault occurs, fault detection for power distribution line could be carried out to extract non-fundamental transient characteristics of zero-sequence voltage by Hilbert-Huang transform. And as long as the fault has been detected by using the Hilbert-Huang transform, the selection of the fault line could be used to fault locating. The Hilbert-Huang transform has been used to fault detection of power distribution line, and the results were compared with wavelet analysis method, which indicates the effectiveness and sensitivity of the proposed method.
