关于ABB DCS系统DSOE的应用与实践

Application and Practice of DSOE in ABB DCS

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1 500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 1 500 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 time interval, they can be captured and their sequence can be DSOE, the hardware, software configuration, common questions purposeful solution scheme is put forward. signals acting at more than 1 ms discriminated. The principle of is analyzed and presented, and
