APLICATION OF INTERNET IN THE SCADA SYSTEM

Abstract

Supervisory Control and Data Acquisition (SCADA) system employ a wide range of computer and communication technologies. Advances in the technologies have helped in improving the effectiveness of SCADA. One such recent technological development is Internet and the World Wide Web. The operational and commercial needs of the power industry require information systems to not only perform traditional functions but also support many of the new functions, specifically to meet the needs of competition with deregulation. The rapid developments of the Internet and distributed computing have opened the door for feasible and cost-effective solutions. This paper describes and demonstrates a unique Internet-based application in a substation automation that is implementing based on the existing control system, SCADA system and information technologies (IT).
