Fault Detection and Location in Low Voltage Grids Based on RF-Mesh Sensor Networks

Abstract

The paper presents the results of the MONITOR BT project with special focus into faults detection and their location in the low voltage (LV) grid and in public lighting feeders. The fault detection and location algorithms run in the Distribution Transformer Controller (DTC) deployed in secondary substation who receive data from monitoring sensors deployed along the LV grid that communicate via RF-mesh. The pilot demonstration of the system was implemented over a selected LV network in Portugal generating results that are also discussed in the paper.

Current and Future Communication Solutions for Smart Grids: A Review

“…Moreover, this technology can be distributed regionally without needing to deploy the entire service territory. RF mesh has self-healing attribute in finding other network configuration in case of node failure [152]. Besides, the RF mesh technology is a self-forming network which enables the signal to find the optimal route back to the head-end system, especially in areas with many obstructions , such as mountains or high-rise buildings.…”

Enhancing Faults Monitoring in Secondary Electrical Distribution Network

“…Due to the complexity and ubiquitous nature of the SDN, cost effective automations are still challenging. Few studies [7] have been conducted in LV distribution network in which controller at the transformer was used as a decision maker. However, advancements in ICT and sensing technologies have made it possible to have cost effective electrical power network visibility and faults handling throughout SDN [8,9].…”
