【摘要】：智能电网成为当今世界各国电网发展的大趋势,且配电网处在电力供应链当中的末端,属于直接面向广大客户的关键能源载体之一,智能配电网的建设与发展是智能电网最基础的组成部分。数据通信系统作为智能配电网实现的基础,属于智能配电网所研究项目当中的重要项目之一,属于非常重要的环节,能够提高供电质量及可靠性、缩小停电范围、缩短事故处理时间等。本论文在智能配电网的概念、功能特征、主要技术和作用意义四个方面展开研究分析,对配电自动化系统结构、配电自动化数据通信的功能、配电自动化数据通信的特点、配电自动化数据通信的要求和配电自动化数据通信规约进行调研分析,对当前常用的四种数据通信方式(电力线载波技术、无源光网络技术、全球微波互联接入技术和分时长期演进技术)在工作原理、技术特点和组网方式等方面进行研究分析,通过对上述四种数据通信方式的分析比较,提出了智能配电网自动化系统数据通信方式选择原则和方案。方案总体采用多级分布式体系结构,结合各地实际,因地制宜,采用复合的数据通信方式,从而达到各地区智能配电自动化系统中数据传输的要求。最后介绍了杭州余杭地区智能配电通信网建设情况,从建设思路、方案设计、方案实施和建设成果四个方面进行详细介绍,提供了余杭城区配电自动化通信网建设实施过程中的一些经验做法。本文提出的智能配电网自动化数据通信系统方案和典型实例对目前实施中的城乡电网改造会有一定的参考价值。
[Abstract]:Smart grid has become the main trend of the development of power grid in the world, and the distribution network is at the end of the power supply chain, which belongs to one of the key energy carriers directly facing the vast number of customers. The construction and development of smart distribution network is the most basic part of smart grid. As the foundation of smart distribution network, data communication system belongs to one of the important projects of smart distribution network, which is a very important link. It can improve the quality and reliability of power supply, reduce the range of power outage, shorten the time of dealing with accidents, etc. This paper studies and analyzes the concept, function characteristics, main technology and function significance of smart distribution network. The structure of distribution automation system, the function of distribution automation data communication, the characteristics of distribution automation data communication, the requirements of distribution automation data communication and the distribution automation data communication protocol are investigated and analyzed. Four common data communication methods (power line carrier technology, passive optical network technology, global microwave interconnection access technology and time-sharing long-term evolution technology) are studied and analyzed in the aspects of working principle, technical characteristics and networking mode. Through the analysis and comparison of the four data communication modes mentioned above, the principle and scheme of data communication mode selection for intelligent distribution network automation system are put forward. In order to meet the requirements of data transmission in intelligent distribution automation system in various regions, the paper introduces the construction of intelligent distribution communication network in Yuhang District, Hangzhou, and designs the construction ideas and schemes. The implementation of the programme and the results of the construction are described in detail in four aspects. Some experiences and practices in the construction and implementation of distribution automation communication network in Yuhang urban area are provided. The intelligent distribution network automation data communication system scheme and typical examples are presented in this paper to reform the urban and rural power network in the current implementation. It has certain reference value.
