As we have adopted the concept of interconnected power system, the role of substation is become more important. Substation connects generation station to the distributor or to the end consumer via transmission system depending upon the types of substation. Activities like switching of transmission lines, parameter measurement, fault detection and storing of historical data are carried out in each of the substation premises. Earlier time this all activities was carried out manually, as complexity of system increase the role of substation become crucial and we need to move towards the use of IEDs and Automation. Activities carried out at substation can broadly classify in to three term i.e. supervision, control and Data acquisition. In an automated substation this all three will done using Programmable Logic controller and SCADA. For system monitoring or supervision data is given to controllers from RTU. Control command according to system parameter is produced by PLC and SCADA provides a human machine interference. Substation automation systems make their control and monitoring possible in real time and maximize availability, reliability and safety of the system.

Substation, PLC, SCADA, RTU.
