摘要
简述了EDPF-NT控制系统的结构特点,以及该项目在国电谏壁发电厂1 000 MW机组中基本网络布置和控制系统运用至今存在的优缺点,重点介绍了国内机组中首次成功运用全国产DCS控制系统实现单元机组炉、机、电集中控制,完成单元机组主辅机及系统的检测、控制、报警、联锁保护、诊断、机组启/停、正常运行操作、事故处理和操作指导等功能,以及其主要的控制策略。
The structure features of the EDPF-NT decentralized control system （DCS） are outlined in the paper, and the existing advantages and disadvantages as well as the basic net arrangement of the system applied in Guodian Jianbi Power Generation Company are also presented. Further, the first successful application of the domestic DCS in one 1 000 MW coal-fired power plant is emphatically introduced. By using this system, the field operators can not only achieve the centralized control of the boiler, steam turbine and electric generator, but also finish a series of important operations including inspection, control, alert, interlock protection, diagnosis, unit start up and shut down, accident disposal and the operating guidance.
