Fujian Luoyuan: Through drone 'leapfrog' inspection, a 'huge improvement' in operation and maintenance quality and efficiency was achieved

China News Service, Fujian News, November 22 (Chen Xia, Chen Xian, Zhou Jun) Recently, in the starting town of Luoyuan County, technical personnel from the State Grid Fujian Electric Power Research Institute and field staff from the Buyang Power Supply Station of the Luoyuan County Power Supply Company conducted After the three drone airports in the jurisdiction were debugged, "leapfrog" drone inspections of line equipment were carried out.

Luoyuan is an authentic mountainous county. Most of the distribution lines within its jurisdiction pass through mountains and forests, and the line inspection work points are wide-ranging. In order to improve the quality and efficiency of power grid equipment operation and maintenance, Luoyuan County Power Supply Company, based on the current status of line operation and maintenance, cooperated with the State Grid Fujian Electric Power Research Institute Machine Inspection Center as a pilot unit to jointly develop "leapfrog" drone inspections technology, deepen the application of autonomous drone inspections, and make inspection work more intelligent and efficient.

According to reports, UAV leapfrog refers to minimizing the correlation between the UAV and the airport, so that when the UAV performs its mission, it can choose the nearest airport for docking and replenishment, so as to support the UAV. The aircraft conducts continuous flight operations in long-distance and wide-range scenarios. In this inspection mode, the operating range of the drone is increased by more than 4 times, and the equipment utilization efficiency is also increased by more than 3 times, thus achieving a leap in the quality and efficiency of line equipment operation and maintenance

"UAV 'leapfrog' inspection has changed the situation of single-point and single-line inspection, realizing 'one machine, multiple fields and multi-grid sharing', greatly improving the efficiency of UAV inspection." Step Lin Yongyin, deputy director of the Yangtze Power Supply Station, said. Taking into account factors such as battery life, power supply, and network access, three airports were deployed this time, namely the rooftop airport of Buyang Power Supply Station, the Nanshan Village Committee Airport, and the 10-kV Banzhang II Return Pole 38 Airport.

Currently, three sets of drone airports have been put into use, increasing the inspection radius of a single drone from 3 kilometers to more than 12 kilometers, covering 13 10 kV overhead distribution lines, 35 kV and There are 150 base towers for transmission lines with voltage levels above, and 2 substations with voltage levels of 110 kV and above. The team plans to build two more airports, and the 5-point connection can achieve full coverage of 20 kilometers of line channels and power facilities.

Immediately afterwards, Luoyuan County Electric Power Company will actively respond to the "Digital Fujian Electricity" ecological construction of State Grid Fujian Electric Power, and closely focus on the "three major and three first" goals of the provincial high-quality development demonstration grid to achieve " We will continue to deepen the construction of new power systems and empower the high-quality development of power grids in our jurisdictions through "digital intelligence" to achieve safer and more reliable power supply.
