SCADA system for a central heating and power plant

Modern process control systems are used in industrial automations for flexibility, modularity and reliability, employing state of the art technology based on three concepts: distributed control system (DCS), programmable logic controller (PLC) and most importantly supervisory control and data acquisition (SCADA). This paper deals with design and implementation of a SCADA system for a central heating and power plant, which is planned to supervise and control field distributed electric devices using Siemens equipment and software ldquoprocess control system 7rdquo (PCS7). The system also allows web-based applications via OPC and Web server by using the existing communication infrastructure. Redundancy is present at the server levels. The system is currently in use at COLTERM Central Heating and Power Plant South (CET South) of Timisoara.
