Design and Simulation of Single Phase Intelligent Prepaid Energy Meter

In this paper, the design and simulation of Intelligent Prepaid Energy Meter (IPEM) has been presented. The objectives of this work  are :( i) to model an IPEM,( ii) to show its reliability on  load measurement ; and (iii) to show graphical behavior of energy consumption pattern of different loads connected to power supply.  The design methodology is Artificial Intelligent (AI) based-using “ knowledge-based” and “cognitive simulation” approach.  The intelligentce properties and expected results of the proposed digital meter was modeled into the system; and was simulated using Matlab /Simulation tool. Results obtained were very satisfactory. If  fully implemented, on one hand, the estimated bills or irregular billing imposed by Power Holding Company of Nigeria(PHCN) on her customers will stop; and on the other hand ,revenue loss through unpaid bills suffered by PHCN will greatly reduce. This will have an overall effects on the nation’s economy as revenue collection will increase. Keyword:Artificial Intelligence, Prepaid Energy Meter, Model, Simulation, Matlab/Simulin

Modelling of the Behavior of Lossless Transmission Lines

The behavior of a lossless transmission line is investigated and modeled in this paper.  Lossless transmission lines as the name implies are lines with little or no signal loss during signal flow. Certain factors are responsible for this condition and they are discussed in this paper. These factors which are applied to coaxial and two-wire transmission lines were modeled using MATLAB in this work; a Graphical User Interface was then incorporated to provide an interactive way of analyzing the effect they have on signal flow efficiency.  The modeling results show why lossless transmission lines are the best choice for optimum transmission efficiency.
