Application of fieldbus control technology in auxiliary shop of power plant

Abstract

Abstract: According to the current practical application situations of the control systems in thermal power plant auxiliary shops, the characteristics of different control systems in auxiliary shops were analyzed. The fieldbus control system was compared with the traditional distributed control system (DCS) and the programmable logic controller (PLC) control system. Taking the boiler makeup water treatment system as an example, the control scheme of fieldbus control system based on PLC was put forward, and its technical economical analysis was carried out.

Key words: auxiliary shop, control system, field-bus control technology, intelligent field device
