Research On SCADA System For Long Distance Pipeline

As an important part of modern national energy construction, the crude oil pipeline has the characteristics of long distance, wide range and great difficulty of production command. As a result of the custody transfer process piping, a unified hydraulic system was formed across the board, so the disturbance of any point of the pipeline will quickly spread across the board. To ensure safe operation of pipelines, oil pipelines must be under timely operational supervision and accurate operational monitoring control. Because of slow reaction and a heavy task load, the way of traditional telephone command, manual record and gradual long-distance pipeline monitoring report are too difficult to meet the requirements of coordinated operation of custody transfer, supply and demand changes, and safe economic operation.With the development of computer science and technology，Industrial control systems based on computer networks occupy an increasingly important position in the production activities.SCADA systems was designed to solve the long-distance oil and gas pipeline monitoring and control,at home and abroad are very widely used for power plants, pipelines and centralized control station,to ensure reliable operation of the production to provide a strong guarantee.The article explores the computer as the core,using modern communication and information technology, industrial technology, intelligent control technology for remote real-time control,collecting real-time information and feedback,and automating decision-making and operations in some key parts,and then complete the oil (gas transmission) oil pipeline across the board and joint gathering station and pipeline networks and other on-site production monitoring and management. In this paper, extend the oil pipeline company oil a Xaohe, Tianciwan-Yuliancrude oil pipeline project as research background,describes the status of theproduction of the project, designed the framework of the SCADA system. Combinedwith the functional requirements of a dispatch center and station pipeline system, Setup the software control system and hardware control system, So as to realize the dataacquisition of pipeline field devices and the process of crude oil pipeline processcontrol. After testing, SCADA systems meet the design requirements of theindicators. The system is proved to be stable and reliable, and its advanced monitoringfunctions can effectively protect the oil’s safe transportation. The automatedmanagement and control system is of high cost performance, which satisfies not onlyrequirements of process operations, but also field management and productionscheduling. Com-pared with the SCADA systems in past slow reaction and heavy taskload, It has achieved a rich functionality, increased the level of automation in thetransport of oil.
