【摘要】：高壓輸電線路進行運行狀態(tài)的在線監(jiān)測,是實現(xiàn)智能電網(wǎng)在輸電環(huán)節(jié)智能化的主要內(nèi)容之一,是實現(xiàn)輸電線路狀態(tài)檢修及全壽命周期管理的主要技術(shù)手段,也是實現(xiàn)輸變電線路運行狀態(tài)的檢修管理、提升電力生產(chǎn)運行管理精益化水平的重要手段。 信息傳輸系統(tǒng)是輸電線路在線監(jiān)測系統(tǒng)研究的重要項目之一,屬于非常重要的基礎(chǔ)性工作,輸電線路在線監(jiān)測系統(tǒng)的基礎(chǔ)是信息傳輸系統(tǒng),輸電線路在線監(jiān)測的在線程度取決于信息傳輸?shù)募夹g(shù)水平與在線監(jiān)測裝置相關(guān)要求的符合程度。本論文主要從輸電線路在線監(jiān)測信息傳輸系統(tǒng)的概念、結(jié)構(gòu)、組成、特點以及建設的標準等方面展開了研究,對當前常用的無線公網(wǎng)(4G)、WIMAX、 Wi-Fi以及光纖通信(工業(yè)以太網(wǎng)交換機)等四種信息傳輸方式的技術(shù)標準、組網(wǎng)方式及特點等方面進行了深入的研究,并對這四種方式進行了分析比較,提出了輸電線路在線監(jiān)測信息傳輸系統(tǒng)選擇的原則和建議方案。方案總體采用光纖通信(光纖工業(yè)以太網(wǎng)交換機)+無線(Wi-Fi)技術(shù)的混合組網(wǎng),這種混合組網(wǎng)方式可以作為當前輸電線路在線監(jiān)測信息傳輸系統(tǒng)建設的指導方案,要利用輸電線路上已經(jīng)有的OPGW光纜、接頭包資源來部署光纖工業(yè)以太網(wǎng)交換機,建設高速可靠的光通信網(wǎng)絡,用于實時性、可靠性很高的一些應用,而在無法部署光纖工業(yè)以太網(wǎng)交換機的桿塔,需要利用無線Wi-Fi技術(shù)來完成信息傳輸通道的延伸。最后介紹了杭州電網(wǎng)輸電線路在線監(jiān)測信息傳輸系統(tǒng)的建設情況,并對方案進行了詳細的介紹。本文提出的輸電線路在線監(jiān)測信息傳輸系統(tǒng)建議方案和案例,對目前正在實施的輸電線路在線監(jiān)測系統(tǒng)的建設有一定的參考價值。
[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.
