| 摘要: |
| 介绍了发电机组锅炉和汽轮机的集散型控制系统(DCS)设计。对煤气燃料控制、送风量控制、引风控制、给水控制、除氧器控制、过热蒸汽温度控制、高压加热器出水温度调节、凝汽器热井水位调节等系统可能出现的问题给出了相应的解决方法,并对系统设置相应的联锁保护。所得出的DCS控制配置方案冗余配置,保障了系统的可靠运行。对所有常规仪表只保留了手操器及几块关键参数的显示表,所有控制、显示、联锁功能全部由系统完成。 |

| Abstract: |
| The design of DCS(Distributed Control System) for power plant boiler and steam turbine control is presented.The solutions are given to the possible problems in different subsystems,such as fuel control system,FDF(Forced Draft Fan) control system,IDF(Induced Draft Fan) control system,feed-water control system,deaerator control system,superheat vapor temperature control system,high-pressure heater water outlet temperature control system,condenser level control system,etc..The system interlock protections are set and the designed DCS is configured in redundancy to guarantee the stable and reliable operation.All functions of control,display and interlock are carried out by DCS,with only a few emergency buttons and meters. |
