【摘要】：隨著社會的發(fā)展,電網(wǎng)己經(jīng)成為現(xiàn)代社會發(fā)展和經(jīng)濟進步的重要保障,其覆蓋范圍越來越廣,不僅覆蓋發(fā)達地區(qū),也已經(jīng)延伸至地質(zhì)和氣候復(fù)雜多變的偏遠山區(qū)。因山火導(dǎo)致線路跳閘停電的情況也時有發(fā)生,給電網(wǎng)的安全穩(wěn)定運行帶來極大的隱患。本課題的目的就是研究在輸電線路遭遇山火災(zāi)害時,如何應(yīng)用山火預(yù)警技術(shù),防止山火造成輸電線路跳閘事故發(fā)生。論文所做的主要工作和成果如下:1.研究了山火預(yù)警的手段和方法,確定了山火預(yù)警系統(tǒng)的設(shè)計要求。首先,對山火引起線路跳閘的機理及原因進行了分析;其次,通過湖北地區(qū)山火跳閘的具體案例分析,得出了山火預(yù)警系統(tǒng)必須具備山火預(yù)警和現(xiàn)場視頻顯示兩大功能,并進一步明確了山火預(yù)警系統(tǒng)的設(shè)計要求;最后通過對不同山火預(yù)警方法的優(yōu)缺點具體分析,確定了一種采用主動預(yù)警方式對山火進行預(yù)警的方案。2.提出了山火預(yù)警系統(tǒng)的總體設(shè)計方案。從山火預(yù)警系統(tǒng)設(shè)計方案的目標和原則出發(fā),通過研究系統(tǒng)的組成及工作方式。重點分析系統(tǒng)應(yīng)用的技術(shù)難點,最終提出了山火預(yù)警系統(tǒng)總體設(shè)計方案。實際應(yīng)用表明該山火預(yù)警系統(tǒng)能夠克服外界環(huán)境影響,實現(xiàn)不間斷精確探測并識別山火。3.詳細設(shè)計了山火預(yù)警系統(tǒng)的各個分系統(tǒng)。從山火識別采集出發(fā),分別研究了基于4G通訊遠程網(wǎng)絡(luò)信息傳輸方法、太陽能供電分系統(tǒng)的供電原理、中心在線視頻監(jiān)視分系統(tǒng)的系統(tǒng)結(jié)構(gòu)和中心軟件管理分系統(tǒng)。通過運用火點定位技術(shù)來采集火源信息確認山火,運用4G技術(shù)來傳輸數(shù)據(jù),太陽能供電技術(shù)來全天候供電,DLP大屏幕墻和基于分布式傳感集中信息處理的監(jiān)控系統(tǒng),完成了各個分系統(tǒng)的設(shè)計。最終表明設(shè)計方案可以實現(xiàn)全天候不停地預(yù)警線路周邊火情,為保證線路運行提供了數(shù)據(jù)依據(jù)。
[Abstract]:With the development of society, power grid has become an important guarantee for the development of modern society and economic progress. Its coverage is more and more extensive, not only in developed areas, but also in remote mountainous areas with complicated geology and climate. The blackout of line tripping caused by mountain fire also happens from time to time, which brings great hidden trouble to the safe and stable operation of power grid. The purpose of this paper is to study how to apply the mountain fire warning technology to prevent the transmission line tripping from occurring when the transmission line encounters mountain fire disaster. The main work and achievements are as follows: 1. The means and methods of mountain fire early warning are studied, and the design requirements of mountain fire early warning system are determined. Firstly, the mechanism and causes of line tripping caused by mountain fire are analyzed. Secondly, through the case study of mountain fire tripping in Hubei area, it is concluded that the early warning system of mountain fire must have two functions: mountain fire early warning and scene video display. Finally, by analyzing the merits and demerits of different early warning methods, a scheme for early warning of mountain fire by active early warning is proposed. 2. The overall design scheme of mountain fire early warning system is put forward. From the aim and principle of the design scheme of mountain fire early warning system, the composition and working mode of the system are studied. The technical difficulties in the application of the system are analyzed, and the overall design scheme of the early warning system for mountain fire is put forward. The practical application shows that the system can overcome the influence of external environment and realize continuous accurate detection and recognition of mountain fire. Detailed design of the mountain fire warning system each subsystem. The remote network information transmission method based on 4G communication, the power supply principle of the solar power supply subsystem, the system structure of the central online video surveillance subsystem and the central software management subsystem are studied in this paper. Through the use of fire location technology to collect fire source information to confirm the mountain fire, using 4G technology to transmit data, solar power technology to power all-weather power, DLP large screen wall and based on distributed sensor centralized information processing monitoring system, The design of each subsystem is completed. Finally, it shows that the design scheme can realize the all-weather warning of the fire around the line, which provides the data basis for the operation of the line.
