The use of supercapacitor in smart metering gateway

Abstract

Advanced Metering Infrastructure (AMI) consists smart meter, gateway, meter data management software. Smart meter and gateway work together to measure energy on the field. Then, gateway send the measured smart meter data that can be periodic or instant meter reading results, power factor, voltage-current-power information. In addition, gateway sends the information to the meter data management system whether there is energy or not by using a communication method in the field. If there is an integration between AMI and other distribution network systems like Outage Management System (OMS), Customer Relations Management, AMI provides measured data to these systems. Supercapacitor (SC) is a new type small energy storage device and it can easily use power system to provide the energy certain time in case of power failure. The gateway that is part of AMI connects the distribution grid physically on the field and provides own energy so when the power failure occurs in distribution grid at same time gateway energy will be cut. This means last measured data and last field situation can’t be send to the AMI software so all system integration and remote meter operation will halt. This paper handles SC usage as a part of AMI system gateway on the field to provide last measured data to the AMI software. SC benefits are shown using AMI system with measured data in distribution grid. SC model will explain considering gateway design. Gateway with SC and gateway without SC situations will compare in terms of AMI and other system integrations.
