摘要
过程层网络化是智能变电站区别于传统变电站自动化系统的一个重要方面。为了研究过程层网络结构的合理选择和优化,使变电站内信息共享达到最大化,文章对目前智能变电站中过程层几种典型的网络结构进行分析比较,归纳总结各方案的优缺点,介绍代表未来发展方向的三网合一方案,并对三网合一方式关键性技术指标进行了实际测试,对今后智能变电站的网络结构设计具有一定的参考价值。
The networked process layer of smart substations is an important aspect different from the traditional substation automation system.To make a reasonable selection of network structure for the process layer and optimize substation＇s information sharing,this paper analyzes several typical process layer network structures used by smart substations,summarizes their advantages and disadvantages.Further,the three nets-in-one solution according with the future development direction is proposed and some key technical indexes are evaluated by actual tests.The solution will provide a reference for the future smart substation＇s network structure design.
