智能变电站过程层网络采用EPON技术实用性研究

Practical Research on EPON Technology Applied in Process Level Network of Smart Substation

本文提出在智能变电站过程层网络通信系统采用EPON进行组网的应用方案,在对智能变电站过程层通信业务分析、及EPON技术和现阶段智能变电站过程层所采用的主流工业以太网技术进行对比分析的基础上,围绕重点关注的SV采样值传输性能及GOOSE传输性能,搭建模拟系统,利用网络记录及分析系统对智能变电站过程层采用EPON组网后的SV传输离散度、GOOSE传输时延进行了分析,分析结果表明在智能变电站过程层采用EPON通信技术不能满足SV和GOOSE的应用需求,本文研究工作是智能变电站及智能电网建设极具现实意义的探索。

This paper proposed an application scheme in which the EPON technology is used in building process level communication system of a smart substation.And analyses the business of communication system in smart substation process level,and also gives a comparative analysis of EPON and traditional industrial Ethernet switch technology,a simulation system has been built to probe the SV transmission and GOOSE transmission performance,and the SV transmission dispersion,GOOSE transmission delay time is researched using network message recorder and analyzer.The result shows that EPON technology can not be used in building process level network of smart substation because it can＇t meet the application requirements.The research work is a great practical significance exploration of smart grid and smart substation development.
