O- t+ e三、第三步各MMI上位机受电：也是先检查DCS配电柜内空开绝缘及线路绝缘，没问题后先合一路再合另一路，最后两路都合上。! L! v* r5 z- i2 l# l3 d% Y5 C四、第四步网络交换机受电：同上。正常后在上位机查看网络状况是否正常。3 n2 w: U; ; E7 O R五、整个DCS系统所有部件都上电正常后(包括检查直流部分的供电及输出是否正常)，进行电源冗余试验及网络冗余试验1 $ ?. p/ A; B- r$ o, I L六、受电过程中应记录各种数据，包括电气至DCS配电柜的电源电压等品质，线路相间绝缘，总开关对地绝缘，控制柜的信号地及安全地的接地电阻，电子间内的温度湿度等，将来写报告及存档用。包括检查DCS配电柜内各小空气开关的相间及对地绝缘（这个用万用表大体测量一下电阻即可），检查各控制柜内接地线与接地铜排连接是否紧密。3 ?0 & o8 B; % v) S/ T; k七、组织分工要明确，包括调试所、电建单位、DCS厂家、监理等单位，谁指挥谁操作谁监护都要明确，确保通讯联系畅通，一有问题马上能快速处理（一般问题不大，但现场首次受电也可能存在些不确定因素），包括两个专业热工与电气（电气只负责把两路合格电源送至DCS配电柜），要有可操作性比较强的受电方案步骤，受电前要进行详细的交底会议，明确各岗位职责，避免误操作。Commission scheme for DCS recovery circuit1 调试目的Debugging purpose1.1 本调试方案规定了分散控制系统（DCS）现场复原通电试验项目及内容；This debugging scheme define decentralized control system(DCS)distribution recovery experiment item and content on site;1.2 调试目的是保证DCS系统软件和硬件工作正常，能实现设计的各种要求，为机组的顺利运行提供保障。The purpose of debugging is assurance DCS system software and hardware to work regularly, and realize various requirements of design ,supply safeguard to the unit to trouble-free operation.1.3 适用于苏丹吉利4期255MW石油焦电站工程分散控制系统（DCS）的现场复原通电试验。Applicable for Sudan Garri 255MW Sponge Coke-fired Power Plant Project, Phase IV decentralized control system (DCS) distribution recovery debugging experiment on site.1.4 系统概况System general situation分散控制系统（DCS）系统设计结构、配置数量、厂家Decentralized control system (DCS) system design structure, allocate numerical measure, manufacturer分散控制系统（DCS）采用新华的OC4000分散控制系统。实现模拟量控制系统（MCS）、辅机顺序控制系统（SCS）、锅炉燃烧管理（BMS）、数据采集和处理系统（DAS）、汽机调速系统（DEH）、停车保护系统（ESD）空压站、吹灰程序控制等多功能一体化控制；Decentralized control system (DCS) uses OC400 decentralized control system of Xinhua.
