Automatic Process Control System of Main Pipeline

Abstract

The article is devoted to the Information system development that allows to automate the pumping process and change the thermal characteristics of pipeline. In winter, influence of temperature leads to significantly increasing of hydraulic friction, that can lead to breaking and oil pipeline “congelation”. The author offers the Information system based on SCADA system with using multifunctional MasterScada platform, which makes possible to perform the oil pumping process simulation and also collection, archiving and displaying of data. It was elaborated structural diagram of data collection that allows to reorganize big data during oil pumping process and monitor the main parameters of pipeline. The functional process scheme of automation the oil transportation process considers in the article, by the example of pipeline section (206 km) between two intermediate pumping stations in the area from Beyneu to Kulsary. The developed system provides continuous working of oil pipeline that decrease energy demands of oil pumping process and workload flow of oil fluid, and also speed up the processes of identifying and troubleshooting of equipment. The advantage of developed Information system is control and automatic regulation of main pipeline parameters during changing of thermal regime. Distinctive feature of the system is that controlling of hot oil pumping process can be realized in real-time mode.
