【摘要】：随着智能电网迅速的研究和发展,电力系统中的光纤通信网络变得越来越重要。由于各种通信技术的不断引入,各种新设备、新系统、新技术在通信系统中应用的数量不断增加,新的问题也在不断出现,因此,电力通信系统中的管理就迫切需要更智能化、更便捷化、更系统化。光纤在线监测系统主要包括光功率实时监测技术、光时域反射技术、自动控制技术、数据库技术等。系统利用数据库存储现有光纤线路的地标信息将OTDR测试得到的故障位置直接显示在地标信息上,可以为维护人员提供更准确直观的可视化故障信息,有效地缩短故障抢修的时间。本文简要阐述了在智能电网高速发展的背景下光纤在线监测系统建设的重要意义、基础理论及其发展。首先对故障定位的方法,现有光纤监测系统的技术缺点和线路维护部分的具体功能需要进行了详细的技术分析。其次,本系统存有每条光纤线路的地标信息和配置,能对光纤网络中工作状态下的光纤进行自动实时地监测,并根据OTDR测试数据,绘出测试曲线,从中得出光纤传输状态具体的分析结论,由此,系统能能够具备提前预防故障发生的功能,还能对于故障光纤快速查询和处理光纤故障位置,通过数据库中光纤线路的具体地标信息可以直观地显示故障位置。在此基础上,根据现场的实际需要,设计了系统的整体结构,并根据工作人员的具体操作编写了系统软件相关的各个功能模块,最后完成了一套完整的光纤在线监测系统。本系统软件采用了简单、直观的微机交互界面,便于人员监控,并具有了实时监测、检测等较为齐全的功能,基本满足了现阶段日常光纤网络维护工作的需求。
[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.
