Applied Research For Manage-Control Integration And Data Integration Of Chuan-Yu Region Natural Gas Pipeline

Natural gas is a clean and high-quality energy. It will be developed and used widely in our country in this century. With the fast development of the natural gas industry in Sichuan-ChangQing region the enlargement and the natural gas pipe network scale in southwest oil and gas field and the expansion of natural gas users , the contradiction between supply and demand becomes obvious .The natural gas production is at full capacity and the pipe network is running at high pressure . There is an urgent need to establish a integrated management and control system efficient management and control of the production, transmission and sale of natural gas. Control and manage the production of natural gasautomaticlly to provide real-time production data for administrative authority and scientific basis for policy.Integrated management and control means that management and control is integrated. It means that by data network systems, the various data of production sites are integrated systematically and technically with various technologies. This lay the foundation for the enterprises to realize automatic data management widely. The goal of integrated management and control sysytem of gas transmission pipeline is that share the data of management system and real-time production system using advanced computer technology and establish integrated management and control data platform of gas transmission network. At the same time, realize the secure and steady schedule by the rapid reponse to the gas network and optimum control and enhance the capacity of early warning for production and running, rapid response and dealing with the emergency. Reduce incident response time and improve management standards and efficiency.The core of the research of integrated management and control sysytem is:1,Establish an integration of data platform: transport the real-time data from the SCADA to the real-time data base in the terminals of the data center where the management, storage and monitoring of the data are processed. Then make analysis, collection and statistics of the production record for the decision-making and management. By integrating both the real-time and management data base and establishing the ties between the real-time and management data to realize the utility and safe share of the data.2,Realize dynamic operation and management of pipe network. It includes: the management of pipe network operation monitoring, security early warning, scale plan and running state.3,Realize the pipe network simulation and optimization subsystem. It includes: steady-state piope network simulation, dynamic pipe network simulation and optimum pipe network running.
