Automatic Meter Reading System: Physical Layer Specification

Partner: 

ENDESA Network Factory S.L.

The introduction of an automatic meter reading (AMR) system can offer several advantages related to the capacity of sending and receiving data between the customer and the electrical utility. Apart from its natural application of electrical power consumption metering, other kinds of information can be also interesting, e.g. time of use, consumption peaks, load balancing, remote control, load connection and disconnection, dynamic billing, fraud detection, etc. Given a LV tree, LV-PLC connects the residential meters to their related concentrator that sends that information to the processing center. From an EU point of view, PLC is the most suitable technology for AMR applications, because it is using an already deployed infrastructure, thus reducing deploying and maintenance costs since the power grid is usually owned by of the same entity that exploits the AMR technology. Current manufacturer solutions, as well as existing proposals, offer limited diversity or, on the other hand, they are too complex to be implemented at a large scale with reduced costs. A zero-crossing synchronized multicarrier based physical layer was proposed at the end of the project. Nowadays that proposal seems to be the current trend in robust AMR modem design.
