A STUDY ON DESIGN AND FABRICATION OF A POWER MANAGEMENT SYSTEM FOR FACTORIES

Abstract

Electricity accounts for a large proportion in the use of secondary energy in factories today.
Economical and efficient use of energy is an urgent requirement for key energy users. However, the
monitoring of the power system in factories is currently mostly done manually. This makes it difficult to
analyze and evaluate the efficient use of energy. In addition, the absence of a monitoring and immediate
warning system in the operation of the power system may cause serious problems such as fire, explosion,
power failure and production stoppage. The economic and human losses in these incidents are enormous
and uncountable. Therefore, it is necessary to apply a real-time power system monitoring system to
monitor, detect and give early warning of abnormal conditions in operation, thereby helping the operator
to remedy the problem timely. This article presents the results of research, design and manufacture of the
power monitoring system for large energy users, thereby helping to use energy economically and
efficiently, reducing abnormal incidents. It also helps to maintenance according to condition (condition
based maintenance - CBM). The main functions are programmed and designed on electronic circuit. The
monitoring program is written on the centralized software to help the operator use it conveniently. The
test results of the proposed system meet the management and operation needs of electric power systems
in factories.
