The State Grid Nantong Power Supply Company in Nantong, Jiangsu province, recently completed satellite remote sensing inspections and intelligent hazard surveys of power lines including the 500 kV Lyuji line. This inspection marks the first independent use of satellite remote sensing to conduct a comprehensive survey of hidden dangers in a 500 kV power transmission line in the city. The 500 kV Lyuji line is the first 500 kV wind power transmission line in Nantong, responsible for integrating over 1.1 million kilowatts of wind power into the Jiangsu power grid each year. The coastal region of Nantong boasts abundant wind energy resources, with the local offshore wind power installed capacity reaching 5.98 million kW so far. This year, over 15 billion kilowatt-hours of clean electricity have been transmitted to the grid. Satellite remote sensing inspections are preferable due to their broad coverage, fewer environmental limitations, high efficiency, and strong targeting capabilities, enabling rapid screening of potential hazards on a large scale. "The efficiency of satellite remote sensing inspections is about 15 times that of manual inspections, and we have identified changes in the status of 297 high-risk hazards through this large-scale satellite survey," said Wen Mingqian, a staff member at the State Grid Nantong Power Supply Company. Currently, the State Grid Nantong Power Supply Company is planning to conduct satellite remote sensing inspections of six 500 kV power lines within its jurisdiction. By combining drones, visual monitoring systems, and ground-based manual inspections, they aim to establish a more comprehensive three-dimensional inspection system to ensure the safe operation of the power grid during the peak winter season. 12月12日,中國日報(bào)發(fā)布《Power lines undergo 1st independent satellite remote sensing inspection》,報(bào)道公司首次采用衛(wèi)星巡視500千伏輸電通道。衛(wèi)星遙感巡視覆蓋面廣,受環(huán)境限制少,具有少人化、效率高、針對性強(qiáng)等優(yōu)勢,可對輸電線路通道開展大范圍的隱患快速篩查。目前,公司正計(jì)劃開展轄區(qū)內(nèi)6條500千伏輸電線路的衛(wèi)星遙感巡視,結(jié)合現(xiàn)有的無人機(jī)、可視化監(jiān)控系統(tǒng)、地面人工網(wǎng)格化巡視處置,推進(jìn)構(gòu)建更為全面的立體巡檢體系,打造“衛(wèi)星+可視化+網(wǎng)格”空天地一體化模式,確保迎峰度冬期間的電網(wǎng)運(yùn)行安全。
