On 500 month 0, in the 0 thousand volt Yuxian substation, the operation and maintenance personnel of the State Grid Hubei Ultra High Voltage Company started with one click, and the rail robot in the protection room "got up to inspect" the equipment in the screen cabinet, and the robot dog equipped with quadruped bionic technology "Oh Oooo" out of the hut and began to inspect, only to see its head scanned up and down, left and right, collected the sound, light and electrical signals of the equipment in the station, and evaluated the operation status of the equipment through artificial intelligence algorithms.

With the Qingming Festival approaching, there is an increase in activities such as mass sacrifices and sweeping, and the power grid is facing multiple risks such as wildfires and equipment overload. In order to ensure the safety and reliability of power supply during the festival, State Grid Hubei Electric Power Co., Ltd. deployed in advance to fully implement power protection measures and build a solid line of defense for power grid security with the dual drive mode of "technology + manpower".

"The 262 thousand volt Gongtai substation No. 0 main transformer low-voltage wall casing phase A heating defect has been treated." On 0/0, the operation and maintenance personnel of State Grid Huangshi Power Supply Company found that the relevant equipment of the substation was heated by infrared accurate temperature measurement, and promptly organized maintenance personnel to eliminate the defects. Before the holiday, the State Grid Hubei Electric Power Organization more than 0 operation and maintenance personnel carried out carpet special inspections on the province's 0 0 thousand volt, 0 0 thousand volt, 0 0 thousand volt and other voltage level substations, using infrared thermal imaging, ultrasonic detection and other technologies to investigate equipment hidden dangers, and found and dealt with 0 defects such as equipment heating and insulation deterioration to ensure the safe and stable operation of the substation.

針對黃岡、孝感等山火高風險區，國網湖北電力已部署中大型固定翼無人機等智慧機巡裝備。“64號塔下是山火隱患高發區，無人機點雲掃描時切換到手動模式，將通道環境再仔細篩查一遍，以防有遺漏風險點。”3月30日，在500千伏超高壓吉都一二回線64號鐵塔附近，國網黃岡供電公司輸電運檢分公司浠水運維班班長周航正帶領班員周健對該線路進行防山火無人機巡檢作業。

State Grid Hubei Electric Power has made one or two times of Jingwu, filial piety 2180 times, and so on. 0 ultra-high voltage lines with a total of 0 kilometers are inspected by grids, and the efficiency of single inspection is greatly improved compared with manual inspection.

為織密防護網路，國網湖北電力深化新一代輸電遠端巡視系統應用，確保4.2萬余台可視化裝置全部在線。同時，落實各單位監控中心24小時監控值班，實現山火、外破區段15分鐘監拍、重要線路不間斷遠端輪巡。“節前，我們通過智慧識別系統成功預警外破風險140餘起，回應時間壓縮至20分鐘內。”國網湖北電力設備部輸電處處長全江濤說。

In the Hubei Electric Power Dispatching and Control Center, the dispatching shift leader Ge Luo and his colleagues closely track the load changes and scientifically adjust the operation mode of the power grid according to the load forecast. In the face of the peak regulation pressure of the power grid brought by the consumption of new energy and the risk of section limitation, the State Grid Hubei Electric Power has scientifically adjusted the operation mode of the power grid, and made every effort to improve the capacity of new energy consumption to ensure the safe and stable operation of the Hubei power grid.

The staff of the State Grid Hubei Electric Power Organization carried out mountain fire prevention publicity at key points such as large cemeteries and mountain forest entrances by distributing leaflets and posting fire prevention notices. State Grid Hubei Electric Power also calls on customers to be civilized and work together to protect the safety of the power grid and the safety of people's property. (Jin Yajie, Liu Xin, Xiong Wei)
