关于ABB DCS系统DSOE的应用与实践

在电厂的生产运行中,SOE的结论对事故的分析、判断起着重要的作用,SOE工作不正常将会误导事故分析的方向,延误分析的进程.DSOE能处理多达1500个开关量,这些点可分布在不同的PCU节点内,分辨率高达1 ms.任意两个开关量的动作时间间隔1 ms以上即能被DSOE捕捉并分辨出动作的先后顺序.对DSOE系统的原理、硬件组成、软件组态、常见问题进行分析和说明,并提出针对性的解决方案.;The conclusion of SOE is very important to the analysis and judgement of accidents in power plants.If the SOE runs in a wrong way,the analysis direction of event will be misled,and the analysis process will be delayed.The DSOE(Distributed Sequence of Events) can process more than 1500 switch signals at 1 ms resolution,which may be distributed in all kinds of PCU(Process Control Unit) grids.This means that if there are any two of switch signals acting at more than 1 ms time interval,they can be captured and their sequence can be discriminated.The principle of DSOE,the hardware,software configuration,common questions is analyzed and presented,and purposeful solution scheme is put forward
