【摘要】：隨著智能電網(wǎng)迅速的研究和發(fā)展,電力系統(tǒng)中的光纖通信網(wǎng)絡(luò)變得越來越重要。由于各種通信技術(shù)的不斷引入,各種新設(shè)備、新系統(tǒng)、新技術(shù)在通信系統(tǒng)中應(yīng)用的數(shù)量不斷增加,新的問題也在不斷出現(xiàn),因此,電力通信系統(tǒng)中的管理就迫切需要更智能化、更便捷化、更系統(tǒng)化。光纖在線監(jiān)測系統(tǒng)主要包括光功率實時監(jiān)測技術(shù)、光時域反射技術(shù)、自動控制技術(shù)、數(shù)據(jù)庫技術(shù)等。系統(tǒng)利用數(shù)據(jù)庫存儲現(xiàn)有光纖線路的地標信息將OTDR測試得到的故障位置直接顯示在地標信息上,可以為維護人員提供更準確直觀的可視化故障信息,有效地縮短故障搶修的時間。本文簡要闡述了在智能電網(wǎng)高速發(fā)展的背景下光纖在線監(jiān)測系統(tǒng)建設(shè)的重要意義、基礎(chǔ)理論及其發(fā)展。首先對故障定位的方法,現(xiàn)有光纖監(jiān)測系統(tǒng)的技術(shù)缺點和線路維護部分的具體功能需要進行了詳細的技術(shù)分析。其次,本系統(tǒng)存有每條光纖線路的地標信息和配置,能對光纖網(wǎng)絡(luò)中工作狀態(tài)下的光纖進行自動實時地監(jiān)測,并根據(jù)OTDR測試數(shù)據(jù),繪出測試曲線,從中得出光纖傳輸狀態(tài)具體的分析結(jié)論,由此,系統(tǒng)能能夠具備提前預防故障發(fā)生的功能,還能對于故障光纖快速查詢和處理光纖故障位置,通過數(shù)據(jù)庫中光纖線路的具體地標信息可以直觀地顯示故障位置。在此基礎(chǔ)上,根據(jù)現(xiàn)場的實際需要,設(shè)計了系統(tǒng)的整體結(jié)構(gòu),并根據(jù)工作人員的具體操作編寫了系統(tǒng)軟件相關(guān)的各個功能模塊,最后完成了一套完整的光纖在線監(jiān)測系統(tǒng)。本系統(tǒng)軟件采用了簡單、直觀的微機交互界面,便于人員監(jiān)控,并具有了實時監(jiān)測、檢測等較為齊全的功能,基本滿足了現(xiàn)階段日常光纖網(wǎng)絡(luò)維護工作的需求。
[Abstract]:With the rapid research and development of smart grid, the optical fiber communication network in power system becomes more and more important. Due to the continuous introduction of various communication technologies, a variety of new equipment, new systems. The number of new technologies in communication systems is increasing, and new problems are also emerging. Therefore, the management of electric power communication systems urgently needs to be more intelligent and more convenient. More systematic. Optical fiber on-line monitoring system mainly includes optical power real-time monitoring technology, optical time domain reflection technology, automatic control technology. Database technology and so on. The system uses database to store the landmarks information of existing optical fiber lines to display the fault location obtained by OTDR test directly on the landmarks information. It can provide more accurate visual fault information for maintainers. This paper briefly describes the significance, basic theory and development of the optical fiber on-line monitoring system under the background of the rapid development of smart grid. Firstly, the method of fault location is discussed. The technical shortcomings of the existing optical fiber monitoring system and the specific function of the line maintenance part need to be analyzed in detail. Secondly, the system contains the landmark information and configuration of each optical fiber line. It can automatically and real-time monitor the optical fiber in the working state of optical fiber network, draw the test curve according to the OTDR test data, and draw the concrete analysis conclusion of the optical fiber transmission state from the test curve, so as to obtain the concrete analysis conclusion of the optical fiber transmission state. The system can have the function of preventing the fault in advance, and can quickly query and process the fault location of the optical fiber. The location of the fault can be displayed intuitively by the specific landmarks of the optical fiber lines in the database. On this basis, the overall structure of the system is designed according to the actual needs of the field. And according to the specific operation of the staff to write the system software related to the various functional modules, and finally completed a complete optical fiber on-line monitoring system. The system software uses a simple, intuitive microcomputer interface. It is convenient for personnel monitoring and has complete functions such as real-time monitoring and detection. It basically meets the needs of daily optical network maintenance at this stage.
