【摘要】：我國建設以特高壓電網(wǎng)為骨干網(wǎng)架的智能電網(wǎng),實現(xiàn)輸電線路的智能化是其中的一個重要環(huán)節(jié),但對智能輸電線路的研究還比較少。本文首先闡釋了智能輸電線路模式,從安全靈活、響應迅速、經(jīng)濟運行、節(jié)能環(huán)保四個方面對智能輸電線路關鍵技術進行了分析,對未來智能輸電線路提出了進一步設想。輸電線路是電力系統(tǒng)的重要組成部分,覆蓋面積比變電站更廣,我國地域廣闊,輸電線路途經(jīng)山區(qū)、盆地、丘陵等多種地形,沿輸電線路走廊,地質(zhì)地貌狀況復雜,氣候環(huán)境多變,常有大風、雷電、重污染、冰雪等極端氣候狀況。輸電線路暴露在環(huán)境中,運行狀況直接受到環(huán)境影響。從上世紀以來,我國多個地區(qū)都曾發(fā)生過由于遭受天氣災害造成的輸電線路故障。輸電線路一旦發(fā)生故障將直接影響電力系統(tǒng)安全穩(wěn)定運行,會給國民經(jīng)濟的生產(chǎn)生活帶來重大損失,危害國家經(jīng)濟發(fā)展和社會穩(wěn)定。對輸電線路設備檢修是保證電力系統(tǒng)正常運行的有效手段,通過設備檢修,可以減少由于設備故障造成的系統(tǒng)停電,提高輸電可靠性。過去采用計劃檢修,已不能適應當前電力生產(chǎn)要求,電力系統(tǒng)狀態(tài)檢修這種方式也應運而生。當前輸電線路各類特征參量的在線監(jiān)測終端已經(jīng)能夠?qū)崿F(xiàn)對線路狀態(tài)監(jiān)測。輸電線路往往處于較為復雜的環(huán)境當中,這就要求監(jiān)測系統(tǒng)能夠綜合監(jiān)測線路運行狀況,并能夠根據(jù)監(jiān)測數(shù)據(jù)診斷出線路故障,為線路安全運行提供決策依據(jù)。為此,本文研究了輸電線路模糊評價理論,通過對數(shù)據(jù)的分析、比較、判別,深度挖掘監(jiān)測數(shù)據(jù),實現(xiàn)對輸電線路設備狀態(tài)的風險評估,為運行維護和管理部門提供檢修決策依據(jù),提前采取維護措施,及時排除線路潛在隱患。最后從國家電網(wǎng)公司建設智能電網(wǎng)發(fā)展戰(zhàn)略的背景和需求出發(fā),對智能輸電線路監(jiān)測系統(tǒng)進行了的總體設計,對系統(tǒng)的開發(fā)目標、設計原則、系統(tǒng)的軟、硬件架構和系統(tǒng)具備的功能進行了具體的論述,研究結果在工程實際應用中易于推廣使用,具有重要的理論意義和現(xiàn)實意義。
[Abstract]:Intelligent transmission line is one of the most important links in the construction of smart grid with UHV grid as the backbone in our country, but the research on intelligent transmission line is still few. This paper first explains the intelligent transmission line mode, analyzes the key technology of intelligent transmission line from four aspects of safety and flexibility, rapid response, economic operation, energy saving and environmental protection, and puts forward a further assumption for the future intelligent transmission line. Transmission line is an important part of the power system, covering a wider area than a substation, China has a vast area, transmission lines pass through mountainous areas, basins, hills and other terrain, along the transmission line corridor, geological and geomorphological conditions are complex. Climate environment is changeable, often wind, lightning, heavy pollution, snow and ice and other extreme weather conditions. Transmission lines are exposed to the environment, and the operating conditions are directly affected by the environment. Since last century, transmission line failures caused by weather disasters have occurred in many regions of China. Once the transmission line breaks down, it will directly affect the safe and stable operation of the power system, bring great losses to the production and life of the national economy, and endanger the national economic development and social stability. Maintenance and repair of transmission line equipment is an effective means to ensure the normal operation of power system. Through equipment maintenance, power system outages caused by equipment failures can be reduced and transmission reliability can be improved. In the past, the use of planned maintenance, can not adapt to the current power production requirements, power system condition based maintenance has emerged as the times require. At present, on-line monitoring terminals of various characteristic parameters of transmission lines have been able to realize line state monitoring. Transmission lines are often in a more complex environment, which requires that the monitoring system can comprehensively monitor the operation of the lines, and can diagnose the line faults according to the monitoring data, and provide a decision basis for the safe operation of the lines. In this paper, the fuzzy evaluation theory of transmission line is studied, and the risk assessment of transmission line equipment is realized by analyzing, comparing, discriminating and deeply mining the monitoring data. Provide maintenance decision basis for operation maintenance and management department, take maintenance measures ahead of time, remove potential hidden trouble in time. Finally, based on the background and requirements of the smart grid development strategy of State Grid Company, the overall design of the intelligent transmission line monitoring system, the development objectives, design principles and soft of the system are given. The hardware architecture and the functions of the system are discussed in detail. The research results are easy to be popularized and used in practical engineering, which has important theoretical and practical significance.
