　大唐南京电厂建设规模是2台660MW超超临界燃煤发电机组。按照大唐集团公司的精神和设计原则：第一要采用新技术，来提高自动化水平，第二要降低电厂的建设投资成本，第三在运行之后，要进行运行方式的改革，以实现减员增效。按照这样一个原则，在辅助车间的技术方案选型上，打破了常规方案的局限，选用了集中控制方案;在硬件平台的选择上，将PLC和DCS放在一起进行比较，最终经过招投标选择了性价比更好，更加适合集中控制应用要求的科远NT6000分散控制系统。同时在部分系统中，采用了现场总线技术，为现场总线技术在火电厂的应用，进行了有益的尝试。
　　1、控制系统配置
　　大唐南京电厂全厂辅助系统(车间)集中控制系统的控制范围包括：综合泵房、净水系统、锅炉补给水系统、两台机组的凝结水精处理及再生设备，化学取样加药系统、机组排水槽、脱硝氨区、工业和脱硫废水处理、生活污水处理、煤泥水处理、暖通、输煤、除灰系统、除渣、电除尘和脱硫等工艺系统。按照工艺系统，控制系统分成水务控制系统、灰煤渣控制系统、脱硫控制系统;其中水务控制系统监控点设在主控室内，灰煤渣控制系统、脱硫控系统监控点设在辅控综合楼，每个监控站均为全功能站，能够监控和操作全厂辅网设备状态，同时通过权限设置不同的用户，区别监视和操作输煤、除灰、脱硫等工艺系统设备，构建了一个全厂辅助车间集中控制系统。
　　1.1、监控点配置
　　本工程设置2个值班监控点和3个后备监控点。值班监控点在正常运行时完成对辅助车间各系统的监控;后备监控点作为调试、试运行、检修时的后备操作点，按无人值班考虑。一个值班监控点设在单元机组集控室内, 配置4 套辅助车间控制系统操作员站，监控对象为水务控制系统;另一个监控值班点设在辅控综合楼，配置6 套辅助车间控制系统操作员站，监控对象为脱硫、输煤、除灰渣系统。辅控综合楼工程师站有脱硫工程师站1 套，辅网工程师站1 套、SIS 接口装置1 台，历史数据服务器1 套。3个后备监控点按无人值班考虑，分别为化学水处理2个后备监控点、凝结水1个后备监控点。后备监控点用于调试、检修及试运行期间的操作，具备针对本系统的独立监控能力与组态调试能力。
　　1.2、控制器与I/O 配置
　　整套控制系统配置25对冗余控制器，IO点配置规模为13000点左右。
　　(1)水务控制系统配置
　　综合泵房、净水处理配置1对控制器;
　　反渗透、化学除盐、再生系统及化学电源系统配置2 对控制器;
　　每台机组的凝结水精处理及汽水取样配置2 对控制器;
　　凝结水精处理再生配置1对控制器;
　　暖通系统配置2对控制器;
　　工业废水处理及脱硫废水配置2对控制器。
　　在废水系统中采用了profibus现场总线技术，每条总线上分别有DP、PA设备组成，DP总线包含的设备有：马达控制器、电磁阀导、电动门执行机构等; PA总线包含的设备有：液位计、压力变送器、流量等。替代了传统IO点300点。现场总线方案与常规系统相比，减少了常规IO模件的使用，减少大量电缆及电缆敷设工作，能够获取总线设备的大量现场信息，降低了工程造价，缩短了施工和调试时间，系统可靠性高，诊断信息丰富，便于后期维护。
　　(2)灰煤渣控制系统配置
　　输煤综合楼、转运站、雨水泵配置2对控制器;
　　输煤码头、煤仓、煤场配置3对控制器;
