摘要
提出了一种基于EPON的电力配电网通信方案,分析了配电网的体系结构,针对不同的配电网架构,设计出不同的EPON通信模式,给出了基于EPON的配电网总体通信方案。采用快速环网保护协议(RRPP),各光线路终端(OLT)通过树形模式、手拉手全光路保护模式和串联多级分光模式与各光网络单元(ONU)相连,实现千兆光口的汇聚。测试结果表明,系统正常工作时,数据传输的上行延时小于2ms,下行延时不超过1ms,完全满足配电网自动化对通信系统的要求。
A communication project of electric power distribution network base on EPON is put forward. The system structure of distribution network is analyzed,according to different structures of distribution network, the different communication models base on EPON are designed. A entire communication project of distribu- tion network base on EPON is put forward. The communication network of the project adopts Rapid Ring Protection Protocol （RRPP）, and the optical line terminator（OLT） connects the optical network unit（ONU） by the models such as tree model, hand-by-hand all optical circuit protection model and multi-grade divided opti- cal in series model, which realizes the influx of kilo-million optical ports. The results of testing demonstrate that when the communication system works normally, the up-delay of data transmission is less than 2ms, and the down-delay is not beyond lms, which entirely meets the demands of communication system for the distri- bution network automation.
