PLC & SCADA Based Effective Boiler Automation System for Thermal Power Plant

SKU: 010161



Boiler is one of the most important equipment in any power plants which require continuous monitoring and inspection at frequent intervals. There are possibilities of errors at measuring and various stages involved with human workers. So a reliable monitoring system is necessary to avoid catastrophic failure, which is achieved by Programmable Logic Controller & Supervisory Control and Data Acquisition system. This paper outlines the design and development of boiler automation system using PLC, SCADA and sensors. PLC and SCADA interfaced via communication cables. The initial phase of the paper focuses on passing the inputs to the boiler at a required temperature, so as to constantly maintain a particular temperature in the boiler. SCADA is used to monitor the boiler temperature, pressure and water level using different sensors and the corresponding output is given to the PLC which controls the boiler temperature, pressure and water level. If the temperature and pressure inside the boiler exceeds the predefined value then the entire system is shut down. In case of emergency different automated check valves are used to release pressure, steam and inform the concerned authority through alarm. Boiler automation ladder diagram is designed using WPL soft and SCADA design is done by Intouch wonderware.
