Design and Implementation of a Remote-Controlled Reliability Analysis and Energy Management System

Abstract

The electricity distributed to any house, school, or industries comes from either Ceylon Electricity Board or Lanka Electricity Company (Pvt.) Ltd. Electricity is bought from LECO or CEB by its consumers under various criteria decided and defined by the Public Utilities Commission of Sri Lanka. These tariffs shall determine the cost to be paid for electricity by each consumer. Usually, due to faults within the consumer’s electrical system within his or her property, the cost they have to pay is not actually the number of units that they consumed. This could be due to a faulty meter or even losses within the factory due to its machines. Power quality decreases due to many faults like this and also due to inductance. Therefore, they will have to pay for more than the units they actually have consumed. To overcome this, we could constantly monitor the system and bring about necessary solutions to fix it as soon as possible. However, doing this manually is tiring and requires the workers to constantly keep measuring the necessary parameters like current, voltage, power, frequency, and power factor. In almost all factories some machines will still be running idle when they actually not used. This project aims to develop an online energy monitoring system that can read data from the supply to factories and also machines and then display them on online application. This will also have the ability to notify on a phone or another app to remind someone to switch off or on any machine. Also, the project aims on carrying out a case study to have a thorough understanding of the factory Randhi International (Pvt.) Ltd., to help in deciding on what solution should be put forth to decrease power loss in any factory the user considers. These guidelines are presented as a case study and will be made into a generalized guide.
