【摘要】：高压输电线路进行运行状态的在线监测,是实现智能电网在输电环节智能化的主要内容之一,是实现输电线路状态检修及全寿命周期管理的主要技术手段,也是实现输变电线路运行状态的检修管理、提升电力生产运行管理精益化水平的重要手段。信息传输系统是输电线路在线监测系统研究的重要项目之一,属于非常重要的基础性工作,输电线路在线监测系统的基础是信息传输系统,输电线路在线监测的在线程度取决于信息传输的技术水平与在线监测装置相关要求的符合程度。本论文主要从输电线路在线监测信息传输系统的概念、结构、组成、特点以及建设的标准等方面展开了研究,对当前常用的无线公网(4G)、WIMAX、 Wi-Fi以及光纤通信(工业以太网交换机)等四种信息传输方式的技术标准、组网方式及特点等方面进行了深入的研究,并对这四种方式进行了分析比较,提出了输电线路在线监测信息传输系统选择的原则和建议方案。方案总体采用光纤通信(光纤工业以太网交换机)+无线(Wi-Fi)技术的混合组网,这种混合组网方式可以作为当前输电线路在线监测信息传输系统建设的指导方案,要利用输电线路上已经有的OPGW光缆、接头包资源来部署光纤工业以太网交换机,建设高速可靠的光通信网络,用于实时性、可靠性很高的一些应用,而在无法部署光纤工业以太网交换机的杆塔,需要利用无线Wi-Fi技术来完成信息传输通道的延伸。最后介绍了杭州电网输电线路在线监测信息传输系统的建设情况,并对方案进行了详细的介绍。本文提出的输电线路在线监测信息传输系统建议方案和案例,对目前正在实施的输电线路在线监测系统的建设有一定的参考价值。
[Abstract]:On-line monitoring of the running state of HV transmission lines is one of the main contents to realize intelligent transmission link of smart grid. It is also the main technical means to realize condition maintenance and life-cycle management of transmission lines. It is also an important means to realize the maintenance management of transmission and transformation lines and to improve the lean level of power production and operation management. The information transmission system is one of the important projects in the research of transmission line on-line monitoring system, which belongs to the very important basic work. The basis of the transmission line on-line monitoring system is the information transmission system. The on-line degree of on-line monitoring of transmission lines depends on the degree of conformity between the technical level of information transmission and the related requirements of on-line monitoring devices. This paper mainly focuses on the concept, structure and composition of the information transmission system for on-line monitoring of transmission lines. In this paper, the characteristics and construction standards are studied, and the technical standards of four kinds of information transmission modes, such as WIMAX, Wi-Fi and optical fiber communication (industrial Ethernet switch), which are commonly used at present, are discussed. The way and characteristics of networking have been deeply studied, and the four methods have been analyzed and compared. This paper puts forward the principles and suggestions for the selection of on-line monitoring information transmission system for transmission lines. The scheme generally adopts the hybrid technology of optical fiber communication (optical fiber industrial Ethernet switch) wireless wi-fie to form a network. This hybrid networking method can be used as the guiding scheme for the construction of the current transmission line on-line monitoring information transmission system. It is necessary to deploy the optical fiber industrial Ethernet switch by using the existing OPGW cables and connectors on the transmission lines. To build a high-speed and reliable optical communications network for real-time, highly reliable applications, and in the case of pole towers that cannot be deployed in optical fiber industrial Ethernet switches, It is necessary to use wireless Wi-Fi technology to complete the extension of information transmission channel. Finally, the paper introduces the construction of information transmission system for transmission line on-line monitoring in Hangzhou Power Grid. The proposal and case of transmission line on-line monitoring information transmission system proposed in this paper have certain reference value to the construction of transmission line on-line monitoring system which is being implemented at present.
