Heilongjiang Power Grid applied for the first time applied to drone independent inspection 500 kV substation

"The route has been selected, and the flying patrol operation can start." On September 13th, at the 500 kV Hunan transformation station in Heilongjiang, with the inspection staff of the Heilongjiang ultra -high -voltage company in Heilongjiang, the unmanned wise patrol cloud nest slowly opened the cloud nest slowly to slowly open open The cabin, the four multi -rotor drones have taken off one after another, accurately positioning through the carrier phase differential technology, and carried out independent inspections on the substation on the substation according to the preset route. This is the first time Heilongjiang Grid has achieved independent inspections of 500 kV transformer power stations.

According to reports, the inspection rely on the drone's autonomous inspection system. The system consists of drones, wisdom -patrol cloud nests and control systems. The drone is equipped with a 20 -megapixel visible light camera and high -resolution infrared camera, and the battery component has its spontaneous heating function. Smart Patrol Cloud Nest adopts advanced landing guidance technology and battery intelligent capture technology to achieve precision landing of drones and rapid replacement of cloud nest batteries to meet the needs of uninterrupted autonomous inspection of drones. In response to the long -term duration and low temperature of Heilongjiang, high -strength plates are used outside the cloud nest, industrial air conditioners are installed inside, and heat -on cotton is paved to deal with extremely cold weather.

During the inspection process, the drone was flying in accordance with the high -precision inspection route to complete the high -definition camera and temperature measurement of the equipment, and the inspection data was transmitted to the control system. After multi -dimensional data analysis Essence

"The technical difficulty of independent inspection in the drone station is mainly to establish a precise three -dimensional model of the real -view station in accurate substation, and planned the feasible inspection route so that the drone can hang in the best shooting position and keep it with the power equipment equipment. Safety distance. "Fu Dongming, the leader of the 500 kV Hanan substation operation and maintenance class, introduced.

To this end, the State Grid Heilongjiang Ultra -high -voltage Company comprehensively considers the seasons characteristics of the area where the substation is located, the safety distance in the substation, and the actual needs of the substation plan. 52 inspection routes have been planned to determine the shooting angle of the drone to ensure that the drone's autonomous inspection inspection successfully launch.
