Protection of MV smart grid based on IoT technology

摘要

In this article, an IoT solution for the management of fault on the medium-voltage (MV) network is presented in a smart grid approach. The goal is to make the electrical substations smart, ensuring that they communicate each other through LoRa protocol. The advantage is to offer a solution that is fast, reliable and with low installation costs. The implementation of logical selectivity makes possible to locate the fault, isolate it and leave the rest of the network powered. The tests carried out and the acquired results, show that the use of this technology allows to obtain the time required for the protection of the MV networks and can therefore be used within the smart grids in the key of Industry 4.0.
