【摘要】：在供电质量、可靠性提升、供电能力扩大以及经济、高效配电网运行目标的实现方面,配网自动化是一种重要措施,此外也是智能配电网得以实现的一个重要基础。在配电网自动化方面,配网自动化通信系统为其中重要的构成部分,是层面内部以及之间诸多功能得以实现的关键所在,承担着如下功能,如命令的返回或者是信息的处理等。若高效而又可靠的通信并不具备,那么数据的传递,或者是配电网以及自动化的联系,自然无法实现。因此,可靠而又安全的配网自动化通信系统的运作,是配网自动化目标得以实现的基础。目前配电网自动化系统主要的通信技术有以太网无源光网络通信技术、工业以太网技术、中压电力线通信技术、无线公网技术、无线专网技术等等。本文根据配网自动化系统的功能实现以及对通信的要求,对几种配网自动化通信技术方案进行了比较,并对比了它们的优缺点,重点对以太网无源光网络技术的原理及关键技术等进行了研究与分析。本文重点介绍了泰州供电公司配网自动化通信实施方案,对总体结构、光通信系统设计、光缆建设等方面进行了分析与总结。光纤通信具有可靠性高、保密性和抗干扰能力强(适用于强电磁干扰的场合)、高带宽等优点,特别是以太网无源光网络光通信技术非常适合于呈带状或链状分布的配网线路,并且具有低成本、高带宽、扩展性强,灵活快速的服务重组等优点。对于“三遥”站点,本期泰州配电通信接入网建设方案均采用以太网无源光网络通信方式。对于“一遥”及“二遥”站点,且敷设光缆比较困难的地区,接入层采用无线公网接入方式。
[Abstract]:Distribution automation is an important measure in the aspects of power supply quality, reliability improvement, power supply capacity expansion and the realization of economic and efficient distribution network operation goals. It is also an important basis for the realization of smart distribution network. In the aspect of distribution network automation, the distribution network automation communication system is an important component, which is the key to the realization of many functions within and between the layers. It undertakes the following functions, such as the return of commands or the processing of information, and so on. If efficient and reliable communication is not available, the transmission of data, or the connection between distribution network and automation, can not be realized. Therefore, the operation of reliable and secure distribution automation communication system is the basis of realizing the goal of distribution automation. At present, the main communication technologies of distribution network automation system include Ethernet passive optical network communication technology, industrial Ethernet technology, medium voltage power line communication technology, wireless public network technology, wireless private network technology and so on. According to the function realization of distribution network automation system and the requirement of communication, this paper compares several schemes of distribution network automation communication technology, and compares their advantages and disadvantages. The principle and key technologies of Ethernet passive optical network are studied and analyzed. This paper mainly introduces the implementation scheme of distribution network automation communication in Taizhou Power supply Company, analyzes and summarizes the overall structure, optical communication system design, optical cable construction and so on. Optical fiber communication has the advantages of high reliability, strong confidentiality and anti-jamming ability (suitable for strong electromagnetic interference), high bandwidth and so on. Especially, the optical communication technology of Ethernet passive optical network is very suitable for distribution network lines with band or chain distribution. And it has the advantages of low cost, high bandwidth, strong expansibility, flexible and fast service reengineering and so on. For "three remote" stations, the construction scheme of Taizhou distribution communication access network adopts Ethernet passive optical network communication mode. For "one remote" and "two remote" stations and difficult to lay optical cable, the access layer adopts wireless public network access mode.
