The Transfer Of Information In On-line Monitoring System For Transmission Lines

Online monitoring of running status of high voltage transmission line, is to realize the smart grid in power transmission link, one of the main content of the intelligent state overhaul is to realize the transmission line and the whole life cycle management of the main technical means, and realize the transmission line running state of maintenance management, improve power production operation management an important means of the lean level.Information transmission system is one of the important projects of transmission line on-line monitoring system for research, belongs to the very important basic work of transmission line on-line monitoring system is the basis of the information transmission system, transmission line on-line monitoring online degree depend on the technology of information transmission and on-line monitoring device to requirements of the relevant degree. This thesis mainly from the concept of transmission line on-line monitoring information transmission system, the structure, composition, characteristics and construction standards carried out research, the current commonly used wireless public network (4g), WIMAX, wi-fi, and optical fiber communication (industrial Ethernet switches) and so on four kind of way of technical standards, networking of information transmission mode and characteristic has carried on the thorough research, and analyses and compares the four ways, and put forward the choosing principle of the transmission line on-line monitoring information transmission system and proposal. General using optical fiber communication, optical fiber industrial Ethernet switches)+a mixture of wireless technology (wi-fi) network, the hybrid network mode can be used as the current transmission line on-line monitoring information transmission system of the construction of the guidelines, to take advantage of OPGW cable, connector packet transmission lines have the resources to deploy fiber industrial Ethernet switch, reliable high-speed optical communication network, used in some applications, high reliability, real-time and in unable to deploy fiber industrial Ethernet switch poles, need to use wireless wi-fi technology to finish the extension of information transmission channel. Finally introduces the transmission line on-line monitoring information transmission system of the city’s power grid construction, and with the introduction of the scheme in detail. In this paper, the transmission line on-line monitoring information transmission system and the proposals for case, on-line monitoring system for transmission line is performed for the construction of the has certain reference value..
