Insulation Monitoring of Dynamic Wireless Charging Network Based on BP Neural Network
The transmission cable and power conversion device need to be buried underground for dynamic wireless charging of an expressway, so cable insulation deterioration caused by aging and corrosion may occur. This paper presents an on-line insulation monitoring method based on BP neural network for dynam...
