一种新型厂站SCADA系统的设计与实践

Design of a new SCADA of the power plants and stations

该厂站SCADA系统是针对所辖多个现场电力子站 (如变电站、发电厂 )的大型企业而设计的,除实现当地SCADA监控子系统外,还需实现远方总工站监控所有现场子站,以及某一大型子站SCADA兼任监控其它子站的功能。该系统利用光纤介质组建以太环环网,保证所有节点机的图形文件、数据共享。采用TCP/IP网络协议及COM/DCOM技术,确保所有相关节点机间数据及图形的实时性、一致性。经过前期充分的分析、设计与开发,该系统现已投入现场运行。实践证明,它不仅具备一般厂站SCADA的功能和特点,而且具备诸多优越性和先进性。

SCADA of the power plants and stations aims at large companies,which control many power field substations(transformer substations and power plants). The SCADA in a great field substation can supervise other substations and engineer station can supervise all field substions. The TCP/IP network protocol and COM/DCOM technique are adopted by a fiber Ethernet loop.It means that all substions' SCADAs share the graphics files and data,keep the consistency of the graphics files and data in real time. The syetem has come to field operation by thorough analysis, design and developing.It is superior to usual SCADA system.
