【摘要】：无人飞行器在电力巡视中的应用已得到国内外专家和企业的广泛关注和研究试验,无人飞行器巡线以其安全、高效的优点成为电力线路巡视的发展方向,又因其特性能够满足即将成为国家主干电网的特高压交流输电线路的巡视要求,而成为研究热点。不过,现在对无人飞行器巡视特高压交流输电线路应用模式的研究不多,且开展的巡视试验多为非特高压、非长距离的输电线路巡视。因此,为得出应用无人飞行器开展常态化的特高压交流输电线路巡视的模式,本文对特高压交流输电线路的缺陷特征、无人飞行器和巡视设备的特性进行研究,在此基础上构建了两大类无人飞行器巡视特高压交流输电线路的应用模式。首先,为得到特高压交流输电线路的缺陷特征,在研究特高压交流输电线路各组成部分及功能后,分析了特高压交流输电线路正常运行时受到的线路电气和机械特性以及线路外部环境对特高压输电线路的影响。结合中国特高压交流输电线路的选型和设计特点,分析了线路本体缺陷、附属设施缺陷和线路外部隐患,通过对缺陷产生机理的分析,得到了缺陷的三个特性,即可见光缺陷特性、热缺陷特性和伴发紫外线特性,为采用新的巡视技术提供了依据。其次,针对特高压交流输电线路主要缺陷的三个特性,提出三种高效的检测技术,并收集相应的典型巡检设备的功能参数。之后,对做为无人飞行器巡线平台的无人飞行器进行分类,着重介绍了固定翼无人机、单旋翼无人飞行器和多旋翼无人飞行器,收集了适用于中国特高压交流输电线路巡视的无人飞行器和技术参数。并以无人飞行器的有效载荷的搭载能力为主要约束,对无人飞行器和三种巡视设备进行匹配,得出多种匹配方式,为发挥各种组合的优势构建巡视模式奠定了基础。最后,总结了特高压交流输电线路巡视的内容,结合无人飞行器和巡视设备的组合特性,构建了单无人飞行器巡视和多无人飞行器协同巡视两大类巡视模式,分析了各个模式的特性和适用情况。选择中国也是世界唯一一条商业运行的特高压交流输电线路长南Ⅰ线山西境内部分的巡视实例对固定翼无人机和单旋翼无人飞行器协同巡视模式进行检验,经检验该模式能够满足大规模特高压交流输电线路巡视的要求。

[Abstract]:The application of unmanned aerial vehicle in power patrol has received extensive attention and research test from both domestic and foreign experts and enterprises, and the unmanned aerial vehicle patrol has the advantages of safety and high efficiency as the development direction of power line patrol. And the characteristics of the invention can meet the patrol requirements of the ultra-high voltage alternating current transmission line, which is to be the national backbone power network, and become the research hot point. However, there is not much research on the application mode of UHV AC transmission line for unmanned aerial vehicle, and the patrol test is mostly non-UHV and non-long-distance transmission line patrol. Therefore, in order to obtain the model of the non-normal UHV AC transmission line patrol, the characteristics of the defect, the unmanned aerial vehicle and the patrol equipment of the UHV AC transmission line are studied in this paper. On this basis, two types of unmanned aerial vehicles patrol the application mode of the UHV AC transmission line. First, in order to obtain the defect characteristics of the UHV AC transmission line, the components and functions of the UHV AC transmission line are studied. The paper analyzes the electrical and mechanical characteristics of the line under normal operation of the UHV AC transmission line and the shadow of the external environment of the line on the UHV transmission line. In response to the selection and design features of the UHV AC transmission line in China, the defects of the line body, the defects of the auxiliary facilities and the hidden danger of the line are analyzed, and the three characteristics of the defect, that is, the visible light defect, are obtained through the analysis of the defect generation mechanism. The characteristics of nature, thermal defect and concomitant ultraviolet are provided for the use of new patrolling techniques. According to the three characteristics of the main defects of the UHV AC transmission line, three efficient detection techniques are put forward, and the work of the corresponding typical inspection equipment is collected. The unmanned aerial vehicle with the unmanned aerial vehicle patrol platform is classified, the fixed-wing unmanned aerial vehicle, the single-rotor unmanned aerial vehicle and the multi-rotor unmanned aerial vehicle are emphatically introduced, and the unmanned aerial vehicle and the technology suitable for the tour of the UHV AC transmission line are collected, The operation parameter is the main constraint of the loading capacity of the payload of the unmanned aerial vehicle, and the unmanned aerial vehicle and the three kinds of patrol equipment are matched, and a plurality of matching modes are obtained, On the basis of the conclusion, the content of the patrol of the UHV AC transmission line is summarized, combined with the combination characteristics of the unmanned aerial vehicle and the patrol equipment, a single unmanned aerial vehicle patrol and a multi-unmanned aerial vehicle are constructed to patrol the two main types of patrol modes, and the characteristics of each mode are analyzed. and is also the only commercial operation of an extra-high voltage alternating current transmission line in the world. The patrol example of the part of the long-south I-line Shanxi domestic part of the long-south I-line Shanxi domestic part of a fixed-wing unmanned aerial vehicle and a single-rotor unmanned aerial vehicle the test is carried out, and the mode can be tested to meet the large-scale extra-high voltage alternating current transmission line,
