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. Keywords: Smart transformer; monitoring; management; diagnostic; fault; CBM. |
