Design and Simulation of Smart Prepaid-Postpaid Energy Meter with Alarm and Theft Control

This paper proposes a mathematical model of multi-featured prepaid-postpaid energy meter. These features are (a) automatic billing, (b) prepaid collection, (c) choice of prepaid or postpaid, (d) detection of abnormal operational condition, (e) protection against electricity theft, (f) data sharing between consumer and utility end, (g) improved accuracy, (h) user friendly as well as economical and (i) motivating towards electric energy conservation. The model uses RS-232 and GSM module for two-way communication. The proposed model is simulated and tested over MATLAB/ Simulink^®platform. The results obtained are promising and complying with the existing features of the energy meter.
