Single Phase Intelligent GSM Based Prepaid Energy Meter

In this project, the design and simulation of Intelligent GSM Based Prepaid Energy Meter has been presented. This system enables Short Message Service (SMS) recharge; accurate calculation of facility’s consumed energy and displays the remaining credit.In electricity generation, transmission and distribution, energy metering plays a vital role for accurate and precise measurement of electricity. Like any other commodity, energy is being measured and monitored for more than 100 years and many new technologies have evolved to derive more benefit from metering systems. In this paper, the design and simulation of Intelligent GSM Based Prepaid Energy Meter has been presented. This system enables Short Message Service (SMS) recharge; accurate calculation of facility’s consumed energy and displays the remaining credit. The energy meter provides the utility company with predefined regular updates of the user’s account through retrieval of the remaining balance of the meter, this is done through SMS. The system enables the utility company to send updated consumption rates to the meter every 12 hours. This system was designed and implemented using Hardware as well as Software. The hardware consisted of analog and digital electronic components while the software was a code that has been written onto the microcontroller in C programming language. A small load had been used in the system design (100 watt Lamp). If fully implemented, this system will improve the utility company efficiency, knowledge of electricity demand trends and needs and availability of up to date customers’ consumption data. This system will ensure high customer satisfaction resulting from easy charging, controlled consumption and threshold alarms. This will have overall effect on the rationalization of the country energy consumption and time management
