基于点对点技术的数字化变电站过程层通信方案

Process Level Communication Scheme of Digital Substation Based on Peer-To-Peer Technology

结合富村变电站的工程实践,介绍基于点对点技术的数字化变电站整体方案,详细论述基于点对点技术的过程层通信方案,重点研究数字化变电站过程层通信的2个关键技术(采样数据同步和GOOSE机制),分析点对点技术在数字化变电站建设中的推广价值,认为点对点技术目前仍是采样值传输的最佳选择。

According to the FuCun substation engineering practice,this paper introduces the holistic scheme of the digital substation based on peer-to-peer technology. This paper particular discusses the process level communication scheme based on peer-to-peer technology, focuses on the two key technologies of process level communication in digital substation： sampling data synchronization and generic object oriented substation event （GOOSE） mechanism, analyzes whether the peer-to-peer technology is worth being popularized in digital substation＇s development, indicates that the peer-to peer technology is still the best choice of the sampled value transmission now.
