Remote Energy Monitoring, Profiling and Control Through GSM Network

This paper presents design and development of a global system for mobile communications (GSM)-based energy monitoring, profiling and control system. The proposed system integrates consumer’s digital energy meter with energy monitoring system which is controlled by electric supply company. Single phase or three phase digital electric meters can be used with indigenously developed add on module, which acquires energy usage data at consumer premises and after necessary processing transmits it to the electric supply company using short message service (SMS) and global packet radio service (GPRS) through GSM network. At the electric supplier end, an energy monitoring system manages all received meter readings, computes the billing cost, updates the database and maintains an energy consumption profile for each consumer. System controls all operations at the electric supply company headquarters and generates various warning alerts on occurrence of faults in the system. A working prototype of complete system has been developed using digital energy meter manufactured by MicroTech Industries, Pakistan, to demonstrate an efficient and transparent means of automatic meter reading, billing and notification using existing wide spread GSM network.
