Abstract

In high voltage substation it’s important to fast simulate and analysis any fault or disturbed in the substation, SCADA system allow to faster analysis of real time and high resolution for the data which allows the operator to take faster decisions at any fault or abnormal condition in the substation. This paper will discuss Supervisory Control and Data Acquisition (SCADA), where the accuracy meaning is a control system with applications in managing large-scale for
industrial operations. The remote substation consists of protection and high voltage equipment that are directly interfaced to supervision center national control; fiber optical connection consists of high quality and fast transmitter data from the protection equipment by SCADA system, power system supervision and power Systems control all working in a coordinated automatic fashion. Data acquisition refers to collecting data in the form of measured analog current or voltages values or the Open or closed status of contact points. Power system supervision is carried out by Operators and maintenance engineers through this acquired data either at a remote site represented by computer displays and graphically wall displays or locally, at the Device site, in the form of frontpanel displays and laptop computers.
