【摘要】：在架空配電線路的運行維護中,故障查找長期以來均是線路維護人員難以解決的問題,現(xiàn)階段并不存在切實有效的檢測設備。故障發(fā)生時,依靠運行維護人員盲目順線路查找,加大了運行維護人員勞動的強度,故障處理難度及處理時間也相應增加,進一步影響了配網(wǎng)線路的供電可靠性。本文是針對查找配網(wǎng)架空線路設備故障點困難的問題,所要研究的內(nèi)容,是在傳統(tǒng)故障指示器基礎上,引進小波分析、無線通信和地理信息系統(tǒng)等技術,通過這些技術的結合,開發(fā)配電線路故障在線監(jiān)測裝置,從而解決線路常規(guī)故障定位困難的問題。開發(fā)出此裝置后,管理人員僅需使用普通計算機作為操作終端,就可方便的登陸監(jiān)控中心系統(tǒng),及時了解配電故障狀態(tài)、快速準確的判斷故障位置、進行數(shù)據(jù)查詢及排除故障。運行維護人員也可以將手機等移動設備作為數(shù)據(jù)接收終端,實時接收故障信息,實現(xiàn)了線路故障定位的綜合自動化管理。該系統(tǒng)成功實施后,將改變目前盲目巡線的現(xiàn)狀。從經(jīng)濟效益來講,減輕運行維護人員勞動強度及勞動時間,節(jié)約了電力系統(tǒng)的人員開支,大大降低了生產(chǎn)運行成本,為電力系統(tǒng)自動化奠定了基礎；從社會效益來講,處理故障的及時性,進一步提高了電力企業(yè)優(yōu)質(zhì)服務精神,避免了社會的不良影響,樹立了電力企業(yè)良好的社會形象。因此該系統(tǒng)必將在電力系統(tǒng)中被廣泛采用,其推廣應用前景十分廣闊。
[Abstract]:In the operation and maintenance of overhead distribution lines, fault finding has long been a difficult problem for line maintainers, and there is no effective testing equipment at the present stage. When the fault occurs, the power supply reliability of the distribution network is further affected by blindly following the line search by the operators and maintainers, which increases the intensity of the labor of the operation and maintenance personnel, and the difficulty of handling the faults and the processing time accordingly, which further affects the power supply reliability of the distribution network lines. In this paper, aiming at the difficulty of finding fault point of overhead line equipment in distribution network, the research content is to introduce wavelet analysis, wireless communication and geographic information system based on traditional fault indicator, through the combination of these technologies. In order to solve the problem of common fault location of distribution line, the on-line monitoring device of distribution line fault is developed. After the development of the device, the manager can easily log on to the monitoring center system by using the common computer as the operation terminal, understand the distribution fault state in time, judge the fault position quickly and accurately, carry on the data inquiry and troubleshoot the fault. Mobile devices such as mobile phones can also be used as data receiving terminals to receive fault information in real time to realize the integrated automation management of line fault location. The successful implementation of the system will change the current situation of blind line inspection. In terms of economic benefits, it reduces the labor intensity and working time of the maintenance personnel, saves the personnel expenses of the power system, greatly reduces the production and operation costs, and lays the foundation for the automation of the power system; in terms of social benefits, The timeliness of dealing with faults further improves the spirit of high quality service of electric power enterprises, avoids the bad influence of society, and sets up a good social image of electric power enterprises. Therefore, the system will be widely used in the power system, and its application prospects are very broad.
