配电网自动化论文：配电网自动化 通信系统【中文摘要】随着我国经济和社会的飞速发展,电力用户对供电质量和供电可靠性的要求越来越高。基于我国信息化建设在经济建设的推动下逐步推广,配电网自动化成为电力系统要实现的目标之一。欧美等发达国家现在已经通过配电网自动化程度的提高,获得了良好的经济效益和社会效益。相对与国外而言,我国的配电网自动化应用研究起步较晚,主要设施和相关技术也比较落后。我国的配电网自动化系统许多问题还没达成广泛共识,还处于建设的起步和探索阶段。配电自动化是对配电网上的设备进行远方的实时监控、协调及控制的一个集成系统。电力系统配电网自动化的各种业务数据的传输离不开通信系统,通信系统的建设是配电自动化系统的关键技术之一。本文主要对郑州市高新技术开发区的配电网自动化试点工程进行研究,调研了项目建设所涉及到地区通信网和中压通信网的现状,对郑州市智能电网发展规划进行了分析。通过对光纤通信方式、中压载波通信方式和无线公网通信方式的研究,确定了以光纤通信方式为主,中压载波通信方式及无线通信方式为辅的混合通信系统,配电通信网络将覆盖到全部的配电自动化主站、终端和相关业务点。使通信网络可以有效满足配电网自动化系统的各种需求。文中根据通信系统的需求及以后通信系统的发展,确定了配电通信系统采用分层的结构,包括骨干层和接入层,通信节点分为通信主站、通信子站和通信终端。骨干层连接配电通信主平台至各配电通信子平台和远程工作站,接入层连接各配电通信子平台至各中压配用电业务终端。系统的网管系统按照功能分为四大模块：配置管理,性能管理,故障管理和安全管理。本文以EPON以太网无源光网络为主要通信系统,在这方面做了较为深入的研究和应用,用其建设主要配电网通信系统。主要项目正在实施。【英文摘要】With the economy and social of our nation have a rapid development, the request of power quality and power reliability to power users was much higher than before. The information construction under the auxiliary of the economic promotes gradually, the Distribution Automation System has become a goal of the Power System. Europe and America and other developed countries have gained lots of economic and social benefits from the higher degree of Distribution Automation System. Relative to the foreign country, the Distribution Automation System beginning in China was late, the main facilities and related technology was also get behind. Many problems of Distribution Automation System have not reached a broad consensus, still in the initial and exploratory stage in China. Distribution Automation System is a real-time monitoring, coordinating and control for power system. Among them, the various data of power system automation transmission can not without communication system. The construction of communication system is one of the key of Distribution Automation System.This paper studies the Distribution Automation Pilot Project of High-tech Development Zone of Zheng Zhou City, research the regional communication network and the status of medium voltage communication network of this project, as well as the development plan of Zheng Zhou smart grid. By the studies of optical fiber communication, power line carrier and wireless communication of network communication, identified the optical fiber communication as the primary way of communication, power line carrier and wireless communication as supplement way and make up an hybrid communication system. Distribution communications network has covered all the main points of distribution automation, terminal and related business point. This communication network can effectively meet the distribution automation system needs.Based on the requirement and the development of communication system, determined the communication system adopts a layered structure, including the backbone layer and access layer, communication node including main platform, sub site and terminal. Distribution communication backbone layer connect the main platform for distribution communication to sub site or remote workstation. Access layer connect the each of sub site and medium voltage electric business terminal. According to the function, the network management system can be divided into four modules:configuration management, performance management, fault management and safety management.In this paper, EPON (Ethernet passive optical network) as the main communication system, in this respect do an in-depth study and application and construction the major distribution communication system. Major projects are being implemented.【关键词】配电网自动化 通信系统 EPON 混合通信【英文关键词】Distribution network automation Communication system EPON Mixed communication【目录】配电网自动化通信系统研究及应用摘要4-5ABSTRACT5-6目录7-101 引言10-191.1 配电网自动化的含义10-121.1.1 配电网及其特点101.1.2 配电网自动化的含义10-111.1.3 配电网自动化的目的及意义11-121.2 实现中低压配电网自动化的必要性12-131.3 国内外配电网自动化技术现状13-151.3.1 国外配电网自动化现状13-141.3.2 国内配电网自动化现状14-151.4 电力通信系统的重要性15-161.5 配电网自动化对通信系统的总体要求16-171.6 本文所作的工作17-192 配电网通信系统现状及规划19-262.1 地区通信网19-222.1.1 地区通信网的现状19-212.1.2 现有光纤网络存在的问题21-222.2 中压通信网22-242.2.1 中压通信网现状222.2.2 中压通信网存在问题22-242.3 配电自动化通信工程规划24-262.3.1 地区通信网规划242.3.2 配用电环节业务规划24-252.3.3 中低压通信网规划25-263 配电网通信方式研究26-393.1 光纤通信方式26-323.1.1 光MODEM设备27-283.1.2 EPON通信系统28-323.2 载波通信方式32-353.2.1 载波通信的特点及优点32-333.2.2 电力载波通信的通信原理和基本构成33-353.3 移动无线通信技术35-393.3.1 GPRS技术36-373.3.2 CDMA技术373.3.3 3G技术37-394 配电网通信系统设计方案39-544.1 配电网自动化总体设计394.2 本论文工程对通信系统的具体要求39-424.2.1 配电网结构对通信网络的影响39-404.2.2 自动化系统对通信网络的要求40-424.3 光纤方案42-504.3.1 建设范围和规模424.3.2 技术方案424.3.3 配电通信网骨干层建设方案42-444.3.4
