变电站综合自动化分布式通信系统研究

论述了分布式变电站综合自动化通信系统的一般结构和特点。针对新建无人值守变电站和旧站改造两种情况分别提出设计、改造方案。方案本着分层分布的思想，使通信系统按任务模块化，模块间并行工作。系统通信速度快，尽量使所有的数据交换并先进赞歌告发一高，某一设备故障不会影响其他设备正常运行；组态灵活，可以在线修改或增减系统配置。所开发的系统已投入运行。

Study on Distributed Communication System of Substation Integrated Automation

General structure and characteristics of distributed communication system of substation integrated automation are discussed .Two designs are given for new and rebuilt non attended substations.Based on dis tributed structure,thecommunication system is modularized accordingtotheirfunctions,each module worksin dependently and simultaneously .The two proposed systems have high reliability,good expendability and rapid dataflows attributed to parallel data transmission .The systems are operatingtwo substations respectively .
