【摘要】 近年来,电网公司已建立起以光纤通信为主的庞大核心通信网络,并延伸覆盖到各发电厂,并以此形成发电-输电-变电的强力电力调度系统。而目前的配用电网络,配网通信一直是一个薄弱环节,严重制约了配用电自动化系统的实现。在过往的配电网通信系统建设中,经历了包括电力线载波、无线通信和目前流行的光纤通信几个阶段,目前电网公司内的配电网自动化通信系统仍然存在上述3种通信方式混合组网的方式,但是从实际使用情况以及电网安全等等角度来看,光纤通信无疑是实现配电网自动化和将来智能配网的最佳通信方式。本文根据配电网自动化系统业务及特点,分析配电网自动化(智能配电网)系统对通信基础架构的需求,并结合某市配电网自动化发展的轨迹,介绍上2代光纤配网通信系统及设备并分析其优缺点;本文着重介绍以太网技术领域下的2个分支——以太网无源光网络和工业以太网技术,分析其核心技术及优缺点,并结合某市供电局2010配电网自动化配套通信工程中对多个厂家工业以太网交换机和无源光网络设备的测试数据,得出以太网无源光网络技术及工业以太网技术在配电网自动化通信系统中的应用适用性、成熟性的结论,并指出存在的问题和改进方向,最后提出以工业以太网技术和以太网无源光网络技术组建配电网自动化(智能配网)通信系统的具体方案。更多还原

【Abstract】 In recent years, power grid companies have been established the huge core net-work in optical fiber communication, which extended cover each power station, and formed electric dispatching system of power generation, transmission and substation. But distribution communication is always a weak links in electric network recently, which restricted the realization of the power distribution automation seriously. We have experienced this several stages of Electricity lines carrier, Wireless communica-tion, and the popular optical fiber communication in the distribution network commu-nication system construction of the past. But judging from the actual use and grid safety etc., the optical fiber communication is easily the best way to realize distribu-tion automation and smart distribution network.According to the business and characteristics of distribution automation system, this paper analyzes communication infrastructure needs of distribution automation (smart distribution grid) system, and introduces the optical fiber to the network com-munication system and equipment of last two generations, and analyzes the advantag-es and disadvantages, based on the trajectory of development of power distribution automation in a city. This paper introduces the two branches under the Ethernet tech-nology areas, Ethernet passive optical network and Industrial Ethernet technology. Based on the test data of industrial Ethernet switches and passive optical network equipment in the power distribution automation system supporting communication engineering in a city power supply bureau,2010, we will analyze the advantages and disadvantages of the core technology, and concluded the Application applicability and sophistication of Ethernet passive optical network and Industrial Ethernet technology in the distribution automation system, and point out the existing problems and im-proving direction, and put forward specific solutions of power distribution automa-tion(smart distribution network) system in communication with industrial Ethernet technology and Ethernet passive optical network technology systemfinally.更多还原
