Research on Accident Inversion and Analysis Method of the Oil and Gas Pipeline SCADA System

It is more intuitive and clear to analyze and judge the pipeline accident with completely inversion and prediction. This paper studies accidents inversion and analysis methods for the oil and gas pipeline SCADA system. First, we save log data and real-time data section in the database and creating event scenes. Then, we use inversion with the accident realtime data section, log data and the timeline playback data. We also use an accident analysis method based on Apriori – a association rules mining algorithm with specified features, to make a preliminary diagnosis for the alarms, accidents, equipment breakdowns, etc. In the industry experiment, this new method is proved to be effective to help the dispatcher locate the accident spot and provide decision support for the reason analysis.
