Abstract： With the overall development of economy and society in China， the demand for power supply in various fields is getting higher and higher， which makes the scale of power grid in our country expand continuously. However， the huge power grid has brought great challenges to its efficient management and operation. Therefore， the strategy of constructing smart grid has been put forward in recent years. The intelligent communication system of distribution network is the first step of building smart grid. Because of the low cost， large capacity and good compatibility of EPON technology， it has been widely used in the communication system of distribution network. This paper first introduces the basic concept of EPON， then analyzes the special advantages of EPON technology， and analyzes the application of EPON technology in distribution network communication system with practical case analysis. Engineering practice shows that EPON has good applicability in distribution network communication system， and it is an important development direction of smart grid in the future. I hope this study can provide a useful reference for the construction of smart grid.

1 概述

配电网是指电网系统中起着电能分配作用的网络，它一方面从输电网接收电能的输入，另一方面通过各种配电设施逐级将电能分配给用户。可见，配电网在电网中起到了极为关键的作用。然而，随着我国电力体制改革的深入，国家提出了建设智能电网的发展策略，而智能电网的实现必须依赖于配电网的自动化。考虑到配电网的覆盖范围极大，涉及的专业技术繁杂、工程建设周期较大，因此对其进行智能化改造并不是一件简单的事情[1]。本文将对EPON技术在配电网通信系统中的应用问题进行深入探讨。……
