Configuration of a Boiler Control System in Thermal Power Plant
화력 발전소 보일러 제어 시스템의 구성에 관한 연구
In this paper, a boiler control system for thermal power plant is configured. The boiler control system for thermal power plant is largely composed of an ABC(Automatic Boiler Control) system and a MBC(Mill Burner Control) system. ABC system controls analog process values, so almost all analog control logic is dealt with in ABC system. On the other hand, MBC system relates to sequence control logic such as MFT logic, Furnace Purge, Safety related logic. Advanced control systems made from advanced countries deal with an ABC system and MBC system in a distributed control system. In this paper, we adopt a DCS as an ABC system and adopt a PLC system as a MBC system to configure a boiler control system for thermal power plant using domestic control system. Finally the validity of the configured boiler control system is shown via simulation using digital simulator for boiler system in thermal power plant.
