硕士论文-高压输电线路在线监测系统的设计与研究,正文共92页。
【摘要】 高压输电线路大多分布在野外,线路覆盖面广,所处的地理环境、气候条件恶劣。传统的人工巡视方法难以保证结果准确无误,而且会耗费大量人力财力和物力,同时也不能做到实时在线测量,效率很低,不能及时发现高压输电线路上存在的安全隐患。为了克服现有技术上的不足,针对高压输电线路自身的特点,本文研究了高压输电线路在线监测系统运行控制策略,采用单片机、数字图像的采集与处理、传感器、3G等无线通信、GIS、数据库等技术,完成了高压输电线路在线监测系统的设计和开发,该系统可及时准确地监测高压输电线路运行状态的变化,将实况视频/图像、音频、现场监测数据以及预警/报警信息通过无线通信网络传送到监控中心,使监控中心运行人员及时掌握高压输电线路的运行状态,实现对高压输电线路的实时监控。文中详细阐述了整个系统的设计过程,介绍了现场多功能监测基站的硬件组成和软件控制,论述了3G视频数据的采集、处理和传输过程,提出了2G控3G的策略,并定义了通信协议的格式和功能,阐述了监控中心软件的设计过程,介绍了高压输电线路在线监测系统的现场测试情况和实际应用效果等。系统经过5个月的试运行,运行稳定,已通过使用单位组织的测试和验收。系统结构合理、功能全面、操作方便、可靠性高、实用性好、野外适应能力强,系统的使用为高压输电线路的管理工作提供了较大的帮助,对于保护员工人身安全、保护国家财产、保证电力系统的安全稳定运行具有重要的现实意义,为我国智能输电系统的发展提供了可靠的技术支持。
【Abstract】 High-voltage transmission lines are mostly distributed in the wild, with a broad covering area, the geographical environment and climatic conditions of which are harsh. Traditional manual patrolling can not assure the accuracy of the results, and will cost a lot of manpower, money and material resources. It can not do real-time on-line monitoring either, and it’s inefficient so that the potential security risks of high-voltage transmission lines can not be detected in time.In order to overcome the deficiencies of existing technologies, according to high-voltage transmission lines’own characteristics, the operational and control strategy of on-line monitoring system for high-voltage transmission lines is studied. The thesis adopts microcontroller, digital image acquisition and processing, sensors,3G and other wireless communications, GIS, databases, programming and other technologies to design and develop an on-line monitoring system for high-voltage transmission lines, which can accurately monitor the changes of operation state for high-voltage transmission lines in time. The live video/images, audio, on-site monitoring data and early warning/alarm information are transmitted through wireless communication network to the monitoring center, so that the operation state of high-voltage transmission lines can be in the grasp of the operating personnels in the monitoring center and the real-time monitoring of high-voltage transmission lines can be achieved.In this thesis, the design process of the whole system is described in detail. The hardware composition and software control of the on-site multifunctional monitoring station are introduced. The collecting, processing and transmission process of 3G video data are discussed, the strategy of 2G controlling 3G is proposed, and the format and the function of communication protocols are defined. The software design process of the monitoring center is described. The test, implementation effect and other actual application of on-line monitoring system for high-voltage transmission lines are introduced.After 5 months of preoperation, the system runs stably, and has passed the test and acceptance organized by the service unit. The system has reasonable structure, high reliability, good practicability and good adaptability to the wild and is full-featured and easy to operate. The use of the system has been a big help for the management of high-voltage transmission lines. It has played an important, practical and significant role in protecting the personal safety of the operating personnels, the property of our state and the safe and stable operation of power systems. And it also provides a reliable technical support for the development of smart transmission system.
