基于KEPServerEX的页岩气场站通信技术研究

Research on Shale Gas Station Communication Technology Based on KEPServerEX

摘要: 针对涪陵页岩气田焦石坝区块试验井组PCS系统不能直接与后期开发井组采用的SCADA系统纳入统一平台进行集中监控的问题，提出了借助第三方OPC服务器整合PCS系统与SCADA系统的通信方案，探讨了KEP Server与PLC及SCADAvantage Explorer与KEPServerEX的通信配置与实现方法，并以Visual Studio 2013软件为主设计了人机交换界面。运行表明：采用该方案可有效完成试验井组生产过程数据与SCADA系统的信息交换，目前在涪陵页岩气田实现了33个集气站和15个井口采气平台无人值守生产。

Abstract: In view of the problem that PCS system of test well group in Jiaoshiba Block of Fuling Shale Gas Field could not be directly integrated with SCADA system adopted by development well group at the late stage for centralized monitoring on unified platform, the communication scheme of inte-grating PCS system and SCADA system with the help of third party OPC server was put forward. The communication configuration and implementation methods of KEP Server and PLC, SCADA-vantage Explorer and KEPServerEX were studied, and the human-machine interface based on Visual Studio 2013 software was designed. Its operation shows that this scheme can effectively complete the exchange of information between the production data of the test well group and the SCADA system. At present, it is used in 33 gas gathering stations and 15 wellhead gas production platforms for unattended in Fuling Shale Gas Field.
