摘　　要：除EPON光纤通信外,配电自动化通信接入网缺乏有效的通信手段,文章提出一种基于数字基带光纤拉远的LTE230 MHz无线通信方案,构建配电自动化通信系统。该方案的核心是将传统基站拆分为基站单元与射频单元,利用光缆资源实现分布式覆盖。分析了方案适用于电力系统需要采用的关键技术,研究了方案的组网结构与特点,设计了方案应用于配电自动化通信的整体架构。基于基带拉远技术的LTE230 MHz无线通信以其频段与组网的优势,将全面解决配电自动化"最后一公里"接入难题。The distribution automation communication access network lacks the effective communication means except for EPON optic-fiber communication. This paper proposes a LTE230 MHz wireless communication scheme based on the remote digital base-band, constructs the distribution automation communication system. The core of scheme is split the traditional base station into base band unit （BBU） and remote radio unit （RRU）, then realizes the distributed coverage based on the optic-fiber resources. This paper analyzes the key technologies of applying to electric power system, researches the network structure and characteristics of scheme, and designs the general frame of applying to distribution automation communication system. With the advantages of band and network, the LTE230 MHz wireless communication based on the remote digital baseband technology will solve the problem of ＂the last one mile＂ of distribution automation.
