SCADA is an acronym that denotes Supervisory Control and Data Acquisition. SCADA is a control system with applications in managing large-scale, automated industrial operations. Factories and plants, water supply systems, nuclear and conventional power generator systems etc are a few examples. The SCADA system consists of one Central Terminal (which could be several kilometers away from the site of operations) and one or several remote sensor terminals close to the site of operations. The sensor units send data to the central terminal which monitors and manages this data. Communication devices, a user interface and the software to make it all work together complete the picture of what makes a SCADA system. Automation systems in a power utility are required for generation, transmission, distribution and management of power in order to increase the efficiency of a power utility
