The design and implementation on the algorithm acquiring SOE data

Abstract： SOE(Sequence Of Event) is used to analyze fault in order to find the cause of the accident in the DCS(distributed control system). In this paper, an acquisition way of the SOE information is studied, it introduces the general structure of the distributed control system, the software deployment of the SOE acquisition system，the communication way between the controller and the operation station, the design technique of the timing system, and the capturing software in the card. This paper focuses on the algorithm through which acquiring the time label of the SOE and the tag positioning method. The acquisition system has been widely applied to the field of the electric power industry, which has the characteristics of high real-time performance and the reasonable algorithm.
