Smart Energy Metering System

Abstract

The objectives of this paper are to develop a system which can transmit the reading of energy meter to the nearest electric meter billing[11][12] and controlling station, to minimize tampering of the reading[20], to identify energy meter breakdown , to minimize administrative expenses, identify excessive power consumption[22] and to facilitate the customer to find its overall consumption of energy continuously. For this we replace analog electric meter with the digital circuitry to provide real time billing & reading to the customers by using Liquid Crystal Display (LCD)[13]. There are basically two ends, one is user end and the other is server end. Either the meter can be prepaid or postpaid, which is completely monitored and controlled by the server end using GPRS connectivity. The user can check its consumption pattern of its usage by login to the website. The unit of measurement is KVA because the Indian power sector faces a serious problem of lean revenue collection for the actual electric energy supplied in VA owing to losses of revenue. One of the prime reasons is the traditional billing system which is inaccurate many times[12], slow, costly, and lacking flexibility as well as reliability. The key elements of this research are micro controller, GSM/GPRS communication module, data sensing network. The whole system is revolving around the GSM/GPRS module and the microcontroller, where GSM/GPRS module is used for the wireless data transmission[7] and controller controls the whole operation of the system[23][24].
