摘　　要：用电信息采集建设是国家电网公司建设智能电网的重要组成部分,用电信息采集的通信系统是智能电网建设的基础平台。文章着眼于用电信息采集通信系统,针对目前主流的用电信息采集通信方式,从组网规模、通信效率、通信可靠性、建设成本等方面进行了对比分析,并结合工程应用提出了基于以太无源光网络的用电信息采集通信方案和具体的技术实现方式。方案具有组网规模大、通信效率高、安全可靠等特点,对用电信息采集通信系统的建设具有积极的参考意义。The construction of electric energy data acquisition is the focus of smart grid construction for State Grid Corporation of China, its system is the basic platform of smart grid construction. This paper focuses on the electricity information acquisition system. For the mainstream communication mode of the electric energy data acquisition, this paper makes the analysis and comparison from the aspects of network scale, communication efficiency, communication reliability, construction cost, and combined with the engineering application, this paper provides the communication scheme of electric energy information acquisition and the concrete realization way based on Ethernet passive optical network （EPON）. This scheme has some advantages, such as a large scale network, high efficiency, safety and reliability, which is of positive reference significance for the construction of the electric energy data acquire system.
