Partial Discharge Detection and Recognition in Insulated Overhead Conductor Based on Bi-LSTM with Attention Mechanism

Abstract: Insulated overhead conductor (IOC) faults cannot be detected by the ordinary protection devices due to the existence of the insulation layer. The failure of insulated overhead conductors is regularly accompanied by partial discharge (PD); thus, IOC faults are often judged by the PDs of insulated overhead conductors. In this paper, an intelligent PD detection model based on bidirectional long short-term memory with attention mechanism (AM-Bi-LSTM) is proposed for judging IOC faults. First, the original signals … Show more

“…This model was used for enhancing PD data in power equipment and detecting PD signals. Xi et al, introduced an attention mechanism (AM) into the PDPR model to improve the recognition accuracy and the computational complexity by emphasizing its effective characteristics and combining the past and future information [15]. They proposed an intelligent partial discharge detection model based on the Bi-directional Long Short-Term Memory (AM-Bi-LSTM) network for identifying partial discharge faults in Insulated Overhead Conductors (IOC)s. Rizzi et al, used a genetic algorithm to extract key features and selected neuro-fuzzy classifiers for PDPR of cable partial discharge [16].…”
