Abstract

The reliable operation of the distribution network is intricately linked to the overall stability of the power system. However, existing methodologies often fall short in precisely identifying the fault location within the electricity distribution network and providing timely warnings prior to the occurrence of faults. The development of electromagnetic sensing theory and artificial intelligence algorithms has provided a new method for the monitoring of distribution networks. To address the inverse problem, this work investigates the field distribution around the distribution network, analyzes the characteristics of the power frequency electromagnetic field and partial discharge field. Furthermore, it conducts an analysis of the feasibility of using electromagnetic sensing theory to monitor the operational status of the distribution network.
