【摘要】：無人飛行器在電力巡視中的應用已得到國內(nèi)外專家和企業(yè)的廣泛關注和研究試驗,無人飛行器巡線以其安全、高效的優(yōu)點成為電力線路巡視的發(fā)展方向,又因其特性能夠滿足即將成為國家主干電網(wǎng)的特高壓交流輸電線路的巡視要求,而成為研究熱點。不過,現(xiàn)在對無人飛行器巡視特高壓交流輸電線路應用模式的研究不多,且開展的巡視試驗多為非特高壓、非長距離的輸電線路巡視。因此,為得出應用無人飛行器開展常態(tài)化的特高壓交流輸電線路巡視的模式,本文對特高壓交流輸電線路的缺陷特征、無人飛行器和巡視設備的特性進行研究,在此基礎上構建了兩大類無人飛行器巡視特高壓交流輸電線路的應用模式。 首先,為得到特高壓交流輸電線路的缺陷特征,在研究特高壓交流輸電線路各組成部分及功能后,分析了特高壓交流輸電線路正常運行時受到的線路電氣和機械特性以及線路外部環(huán)境對特高壓輸電線路的影響。結合中國特高壓交流輸電線路的選型和設計特點,分析了線路本體缺陷、附屬設施缺陷和線路外部隱患,通過對缺陷產(chǎn)生機理的分析,得到了缺陷的三個特性,即可見光缺陷特性、熱缺陷特性和伴發(fā)紫外線特性,為采用新的巡視技術提供了依據(jù)。 其次,針對特高壓交流輸電線路主要缺陷的三個特性,提出三種高效的檢測技術,并收集相應的典型巡檢設備的功能參數(shù)。之后,對做為無人飛行器巡線平臺的無人飛行器進行分類,著重介紹了固定翼無人機、單旋翼無人飛行器和多旋翼無人飛行器,收集了適用于中國特高壓交流輸電線路巡視的無人飛行器和技術參數(shù)。并以無人飛行器的有效載荷的搭載能力為主要約束,對無人飛行器和三種巡視設備進行匹配,得出多種匹配方式,為發(fā)揮各種組合的優(yōu)勢構建巡視模式奠定了基礎。 最后,總結了特高壓交流輸電線路巡視的內(nèi)容,結合無人飛行器和巡視設備的組合特性,構建了單無人飛行器巡視和多無人飛行器協(xié)同巡視兩大類巡視模式,分析了各個模式的特性和適用情況。選擇中國也是世界唯一一條商業(yè)運行的特高壓交流輸電線路長南Ⅰ線山西境內(nèi)部分的巡視實例對固定翼無人機和單旋翼無人飛行器協(xié)同巡視模式進行檢驗,經(jīng)檢驗該模式能夠滿足大規(guī)模特高壓交流輸電線路巡視的要求。

[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,
