【摘要】：近年来,随着以特高压为代表的电力骨干网架的逐步建成使得我国大多数地区的高压输电网络已相对完善,而电网智能化和分布式能源、电动汽车、储能系统等新型电力网络节点的接入使得未来十年配电网将成为电网建设的新重点。同时,伴随我国全面的城市化建设,电力通信系统的建设开始从高压电网向中低压电网延伸。在满足对可靠性、安全性、实时性等高要求下,光纤的大量建设也带了高昂的建设成本与门槛,于是在很多的实际项目中,GPRS这样的无线电信公共网络作为备用方案得到了广泛使用。在初期的建设热潮过后,业内开始再次正视与思索配电通信网络的建设如何更好地兼顾实用性与前瞻性,而作为电力系统传统的电力线载通信技术也被科研机构与电力客户重新提出。本文首先对宽带电力线通信技术的产生背景与发展现状进行了简要介绍,从配电网现有通信网络的结构缺陷、配电网业务需求、宽带电力线技术特性等三方面着手,对其在配电网中使用的适用性与技术原则详细阐述,并给出明确结论。其次,由于配电网在结构和输电网络存在较大的差异,本文一方面通过对配电网基本结构的分析典型模型,以构建适合于宽带电力线的配电网中国典型的网络模型,另一方面研究其在工程应用中信道量测方法与经验方法,最后通过实际工程项目加以验证与优化。本文最后设计的宽带电力线通信远程网络监控系统的系统结构设计和主要功能是建立前述的工程应用研究的基础的,该系统的目的是实现宽带电力线通信网络的自动运行分析与管理,它更加完善了宽带电力线的应用体系。
[Abstract]:In recent years, with the gradual completion of the backbone grid, represented by UHV, the HV transmission network in most areas of our country has been relatively perfect. The connection of new power network nodes, such as energy storage system, will make the distribution network a new focus in the next ten years. At the same time, with the overall urbanization in China, the construction of electric power communication system began to extend from high voltage power grid to medium and low voltage network. In order to meet the high requirements of reliability, security, real-time and so on, a large number of optical fiber construction has also brought high construction costs and thresholds. Therefore, in many practical projects, wireless telecommunication public network such as GPRS has been widely used as a backup scheme. After the initial construction boom, the industry began to face up to and ponder over how to better balance practicality and foresight in the construction of distribution communication networks. As a traditional power line communication technology, power line-borne communication technology has also been put forward by scientific research institutions and power customers. In this paper, the background and development status of broadband power line communication technology are introduced briefly, from three aspects: the structural defects of the existing communication network, the service requirements of the distribution network, and the characteristics of the broadband power line technology. The applicability and technical principle of its application in distribution network are expounded in detail, and a clear conclusion is given. Secondly, because there are great differences between the distribution network structure and transmission network, on the one hand, this paper analyzes the typical model of distribution network basic structure, in order to build a typical distribution network model suitable for broadband power line in China. On the other hand, the channel measurement method and the empirical method in engineering application are studied, and finally verified and optimized by the actual project. The system structure design and main functions of the broadband power line communication remote network monitoring system designed in the last part of this paper are the foundation of the above-mentioned engineering application research. The purpose of this system is to realize the automatic operation analysis and management of broadband power line communication network, and it improves the application system of broadband power line.
