SCADA .doc --- SUPERVISORY CONTROL AND DATA ACQUISITION (Paper Presentation)

ABSTRACT

”The Energy is neither created nor destroyed” and the energy is generated, transmitted, distributed and finally utilized. At every stage certain supervision, control and protection is necessary. This paper deals with basic SCADA system, its components, basic block diagram, functions, applications and advantages of SCADA.

SCADA helps in monitoring the system and have alarm generation facility incase of faults, which helps in real time analysis. This paper deals with the data logging ability of SCADA enabling off line analysis. Thus remote control over power system is achieved by SCADA, which is effectively depicted in this paper.

This paper is an attempt to highlight the features of SCADA, which is a revolutionary development in automotive monitoring and control of process. The need for SCADA as well as its hierarchical structure has also been mentioned in the paper. The component of SCADA, which is divided into two parts hardware and software, has also been taken in detail. Features of the SCADA such as simulation options, data import and export function has also been taken into account. A criterion for economic operation of grid as well as states in which it operates has also been considered. Security and reliability which is a prime factor for automated systems has been explained to us..

INTRODUCTION:

These days sophisticated working environment has become a need of the hour. Analysis of the following problem would make the need more specific. For example: Central Railways cover a large and extensive area and efficient operation of such large network is must. Consider that circuit breaker near remote place has tripped and the supply has been cutoff. The power supply has to be restored as early as
