智能配电、用电远程通信技术分析

Analysis of smart distribution power telecommunication technology

针对智能配电、用电系统的远程通信需求,以典型的配电、用电用户需求模型为对象,对SDH/MSTP、工业以太网交换机、EPON技术、GPRS/CDMA技术在同一平台上进行比较分析。通过综合分析推导出各种通信技术的优缺点,并提出了各自的适用范围:工业以太网交换机适合于用户分散的低密度地区接入网建设;SDH/MSTP适合接入容量大、业务要求高的大客户的多业务综合接入;EPON技术具有灵活的组网能力和经济适用能力,非常适合智能配用电系统对通信接入应用的要求。

In light of the communication need of smart distribution and utilization power,Variety of communication techniques including SDH/MSTP,industrial Ethernet switches,EPON,GPRS / CDMA were compared on the same platform that a typical Smart Distribution Power user model.We derived the advantages and disadvantages of various communication technologies,and put forward their own scope of application： Industrial Ethernet switches are suitable for construction of the access network in Users scattered low-density areas;SDH/MSTP are suitable for construction of High-capacity,high-quality multi-service integrated access;EPON technology has flexible networking capabilities and economic applicability,well suited for smart power system of communication with access applications.
