Modeling and Design of Smart Card Prepayment System for Efficient Utilisation of Electrical Energy in the Distribution System

Today the metering instrument technology grown up significantly, such that the Consumed energy can be calculated mathematically displayed, data can be stored, data can be transmitted etc. Presently the micro-controllers are playing major role in metering instrument technology. The present project work is designed to collect the consumed energy data of a particular energy consumer through wireless communication system (without going to consumer house), the system can be called as Automatic Meter Reading (AMR) system. The automatic meter reading system is intended to remotely collect the meter readings of a locality using a communication system, without persons physically going and reading the meters visually. The application of the e-metering system is extended to streamline power distribution with online monitoring of power quality, real time theft detection and automatic billing. The power utility can recharge the prepaid card remotely through mobile communication based on customer requests. The proposed prepaid meter is implemented in a software model and MATLAB has been used for simulation. This meter has the characteristics of high accuracy, prepayment, multi-metering, agile measuring approaches, different events record and complete data freezing.
