长输天然气管道站控系统工控安全方案设计与研究

Research on Security Protection for Station Control System of Long-Distance Natural Gas Transmission Pipeline

盖州压气站工程是我国石油天然气管道基础设施互联互通的重点项目,该压气站是缓解我国京津冀和东北部地区冬季用气紧张的关键民生工程.该项目作为自动化试点工程,国产PLC设备、“一键启停站”国产技术第1次在我国长输管道中应用,填补了我国天然气管道核心国产化设备的空白.近年来,随着两化融合的不断深化,工业控制系统网络安全问题也接踵而至,严重威胁到企业乃至国家安全.针对盖州压气站的站控系统安全防护进行了研究,给出了设计方案以及部署实施.

The Gaizhou compressor station project is a key interconnection project of national natural gas infrastructure,and also a civil engineering project to alleviate gas shortage in Northeast China and Beijing-Tianjin-Hebei region in winter.As a pilot project,the domestic PLC software and the“one-key start-stop”technology are applied for the first time in domestic long-distance pipelines,filling the gap of the core domestic industrial control equipment.In recent years,with the deepening of IT&OT,the network security problems of industrial control systems have come one after another,which seriously threatens the security of enterprises and even the national security.In this paper,the safety protection of station control system in Gaizhou natural gas compressor station is studied,and the design scheme and deployment implementation are given.
