摘要
针对国产DCS缺乏大型机组应用经验的问题,介绍了国产DCS系统XDPS在600 MW亚临界火电机组中的具体应用,描述了贵州盘南电厂3#,4#机组DCS及公用系统的I/O配置、硬件配置、网络拓扑结构及软件控制策略,控制范围包括DAS,MCS,SCS,FSSS,TBC和ECS等子系统。优化的I/O分布,冗余容错光纤环网,全能操作员站,分散布置冗余备用的控制器DPU,灵活的通讯接口,方便的组态工具,完善的控制策略说明XDPS400+系统对600 MW及以上容量大型火电机组具有可靠、完整的解决方案。
Because of lacking on application experience in mass capacity power generate unit,detailed engineering application of XDPS system in 600 MW sub-critical power generating unit is introduced.I/O configuration of 3#,4# unit DCS and their common system,in Pannan Power Plant,Guizhou,as well as hardware configuration,network structure and software control policy are described.Scope of control system includes sub-system of DAS,MCS,SCS,FSSS,TBC and ECS.Characteristics as optimised I/O dstribution,redundant and fault tolerant optical fiber ring network,omnipotent OPU,distributed and redundant controller-DPU,flexible communicating interface,convenient configuration tools and perfect control policy,all proved that XDPS 400+ system has fully reliable and integrated solution to 600 MW and more mass capacity power generating units.
