Abstract

An AMI involves multiple heterogeneous devices, often produced by different manufacturers and which play different roles in the infrastructure, that need to communicate among each other. The DLMS/COSEM seems a good candidate to fulfill the requirement, being targeted to smart meters and supporting different communication channels. However the time resolution provided by the DLMS is in the order of hundredths of seconds: such resolution combined with an appropriate synchronization protocol could contribute to obtain measurements with sufficient resolution in time to make possible an accurate analysis of the power quality in customer’s premises. In this paper, the authors will integrate the synchronization capabilities offered by DLMS with some synchronization protocols for WSN making comparisons and reporting on performances and applicability.
