A diagnostic method for power line networks by channel estimation of PLC devices

Cost efficiency and supply reliability are of major interest for power grids and networks. Therefore, we introduce a novel approach for power line diagnostics using channel measurements of power line communication devices. This approach does not require the test subject to be taken out of service. Periodic channel measurements provide insight into possible quality degradations of the cable as well as information to locate a degradation. A proof of concept is provided via simulation for a point-to-point connection of two power line devices. We show to which extent reliable information can be obtained for the test subject and investigate the influence of various parameters.
