Digital energy monitor: design, simulations and prototype

Abstract

This paper demonstrates the design and implementation of a GSM based digital energy monitoring device. Firstly fuzzy based model is developed to replicate the characteristic of current and voltage sensors. The entire system is also studied and simulated in terms of utility side supply, load, microcontroller digitization and GSM communication. A virtual data sharing technic is also studied for the proposed system using state flow logic. A prototype system is verified real-time with its test and verification phase results. In this work, remote monitoring of electricity has been made easier for the utility. Demand side management is also presented as customers can instantly get their electricity consumptions when requested. Further, an effective overcurrent monitoring system has been embedded along with a backup battery source. Results obtained from the experiments prove that with this emerging technology it is possible to move towards a smarter grid at a rapid and cost effective way.
