A proposal for standardized data models and exchange information protocols applicable in centralized metering systems

Abstract

The non-technical energy losses reduction strategies have stimulated the development of centralized metering systems (cms) in Latin America. Furthermore to include ami systems basic functions, the cms embed the measurement of multiple users in a cabinet. To avoid the utility customers getting access to the energy meter, each cabinet is mounted on top of an electrical pole. Currently, the major commercially available cms equipment is setting up with several technologies, which involves owner interfaces and data models. This issue generates an interoperability problem since international standards are based on measurement architectures for the use of individual meters. This paper proposes a set of both information exchange protocols and standardized data models that could be implemented in cms equipments.
