摘要
主要阐述了EDPF-NT+系统的冗余设计及其在火力发电机组中的重要性。EDPF-NT+系统设计实现了火力发电机组的电源冗余、控制器冗余、网络冗余、操作员站冗余、历史站冗余、I/O通道冗余,该冗余设计保证了火力发电机组DCS安全运行,在维持机组安全稳定运行方面发挥了重要作用。
This paper mainly elaborated the redundant design of EDPF-NT＋ system and the importance of redundant design in thermal power plant.The redundant design of EDPF-NT＋ system includes power redundancy,thermal power unit controller redundancy,network redundancy,operator station redundancy,historical storage and retrieval station redundancy,I/O channel redundancy.The redundant design is contributed to the DCS safe operation of thermal power generating units,plays an important role in the safe and stable operation of the unit.
