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..
