Study And Implementation Of Network Communications For HeNan EMS Interconnection Project

Along with the development of power system dispatching technology, power system dispatching demands more, faster, and more accurate information of primary power system, the development of communications technology can be a strongly base for transmission of such infomation.This dissertation simply introduces EMS/SCADA system and its basic function and architecture through HeNan EMS interconnection project, it focuses on practical discussion and development of data acquisition module of SCADA/EMS system, introduces manufacturing message specification (MMS), field device model, inter-control center communications portal(ICCP), analysis TASE.2 portal's characteristic in comparison with traditional telecontrol portal. It expatiate network communications methods based TASE.2 portal and measure on safety and reliability in SCADA/EMS system, and introduces popularization and development foreground of TASE.2 portal in real-time information communications in HeNan power system based on former discussion.
