Smart Prepaid Electricity Energy Metering and Power Theft Control System Using Gsm

Abstract

In developing countries the utilities are facing difficulties in collecting electric bill in full scale. The conventional method of electricity billing involves a person from the distribution unit reading the number of units of electricity consumed in the energy meter and then preparing  the bill. So the task of billing for every consumer is a time consuming  job for the distribution grid and there can be errors in human reading. To eliminate all these problems ,the most convenient method is making the whole system prepaid  similar to mobile phone recharge or DTH recharge. Therefore prepaid energy metering  system is becoming  popular for ensuring the collection of bill in advance .In this system the energy measurement  and billing system is automated using ATMEGA 89S52 Microcontroller and  GSM. The electricity recharge is simply done by sending an SMS through the mobile phone. The Microcontroller  stores the number of units allocated and measures the energy consumed. It can also disconnect the home power supply if there is zero balance in the energy meter. The system will read the energy meter readings  and also send  notifications to the users mobile phone like low balance alert, recharge alert etc. Also today a huge amount of revenue is lost due to power thefts .This project also helps  in minimizing the powertheft. It is a user friendly project. Wastage of energy will be reduced to a great extent. Using this project we can reduce manual effort to take the readings from the energy meter which is cost effective. The system have large  scope of development that can contribute to great innovations.
