后备监控设备的配置
根据已建成300MW机组的运行经验，九江、信阳、益阳电厂机炉控制中采用DCS以CRT和键盘监控为中心后，尽可能地减少控制盘台上的显示仪表、操作器／开关、报警窗等，仅保留的后备监控设备为：
（1）模拟量信号全部进DCS显示，盘上仅保留少量显示仪表。
（2）只保留少量的重要电气开关并取消电气控制屏／盘，控制功能在DCS实现。关于手动同期开关的保留与否，由于自动准同期装置产品的可靠性已越来越高，建议取消手动同期开关。保留的后备手操开关为：发变组断路器紧急跳闸按钮；发电机灭磁开关跳闸按钮；柴油发电机紧急按钮。
（3）报警光字牌数量保留20个左右，与热工报警合并在一起，既减少了设备的种类，又便于布置。
6 公用系统控制方式
对于2台机组的公用系统，如厂用公用及备用电源系统等与热工控制系统一样，DCS的配置能够实现机组停止时，另一台机组的运行人员能对公用系统进行监控，并且要求采用可靠的措施，确保其控制命令的唯一性，即在同一时间只允许一套DCS系统对公用设备起控制作用。不能因为公用系统的存在，而使2台机组的DCS耦合在一起。
在工程实际应用过程中，依照DCS的特点采用了2种典型的方法来实现对公用系统的控制。九江三期的DCS是HITACHI公司生产的HIACS7000系统，在DCS的配置中，我们在2台机组中配置相同的硬件和软件，通过切换开关来实现操作权的转换。外部设备的信号通过冗余配置(模拟量)或通过扩展转换(开关量)分别送入2套DCS系统。同时因保证不出现误操作事故，还增加了相当部分的判据条件和I／0测点，这种方式的优点是当一台机组停运或检修，可以较方便地对DCS进行检查，同时也增大了控制的可靠性，缺点是增加了外部设备的数量，增加了费用。增加一个环节也就意味着增加了故障发生的可能。信阳一期、益阳一期的DCS是由Bailey公司提供的INFI-90系统，针对其系统结构采用了公用环，公用系统的控制全部通过公用环配置来实现。2套DCS通过Tagnumber来实现控制，这样较好地解决了耦合问题。这种控制方式的优点是配置较少，外部设备也不用增加，有效地利用了信息资源；缺点是公用环的设备不能停电检修，除非2台机组均停机检修，加重了设备运行安全性的要求。
