From September 28 to October 3, the 13th China International Air Show (hereinafter referred to as the Air Show) was held in Zhuhai. The Guangdong Zhuhai Power Supply Bureau of China Southern Power Grid continued to strengthen the safety and stability of the power grid, reliable power supply, and safety protection of power facilities. , To provide a strong guarantee for the reliable power supply for this Zhuhai International Air Show.

　　 The biggest difference between this year's air show and previous years is the first launch of the "online air show", which puts high demands on the power supply. On the basis of ensuring the safe and reliable power supply of the exhibition halls, the Guangdong Zhuhai Power Supply Bureau of China Southern Power Grid deploys generator cars according to the needs of the "online air show" to ensure the power consumption of the air show news center. In addition, technicians are arranged to be on-site to ensure the power supply to key locations of the air show to ensure the safe and reliable operation of media relay vehicles and other equipment during the "online air show". 8 500 kVA emergency generator cars, 1 generator and 1 UPS power car were stationed in the air show center ahead of time on this year’s air show, as a power-guaranteed load for emergency power supply, compared to the previous air show’s emergency generator car Power has more than doubled.

　　 It is understood that the scale of this year's Zhuhai Air Show is larger than that of previous editions, and the number of exhibition halls has increased from 8 in the previous edition to 11. In order to ensure the safety and reliability of power supply, the staff of the Guangdong Zhuhai Power Supply Bureau of China Southern Power Grid has taken the initiative to visit from April this year, carefully communicated electricity demand, sorted out 35 air show tasks list, and meticulously compiled work plans to ensure power supply; The airshow center users communicate and coordinate, carry out large-scale investigation and rectification of equipment hidden dangers, monitor the status of power supply equipment, implement management and control measures to prevent damage from external forces, carry out rehearsal of sudden power outages at airshows, strengthen emergency duty management, and prepare spare parts Reserve work to ensure that you rush to the scene as soon as possible when a hidden danger occurs, and eliminate the hidden dangers of equipment and lines as quickly as possible. At the same time, it arranged for professional inspection personnel to deliver services to the door, assisted navigation exhibition center users to carry out equipment hidden danger "physical examination", and conducted cable shock wave test, heavy load test, and emergency drills on power supply lines, switch stations and other electrical equipment in the exhibition hall Waiting for work, ranging from transformers to switches and plugs, every detail strives to be precise and accurate, and the electricity before the opening of the Haohang Exhibition is turned off.

       According to the important places and professional work of the air show, the Guangdong Zhuhai Power Supply Bureau of China Southern Power Grid has established 13 power supply teams in the aviation exhibition hall, distributed in important places, responsible for the operation of power generation vehicles, UPS emergency handling, temporary changes in the air exhibition hall and Professional work such as low-voltage inspections. In addition, a power supply team outside the air exhibition hall is organized, mainly responsible for the inspection of the power supply lines around the exhibition hall.

　　 Compared with previous editions, this year’s airshow has innovated the method of ensuring power supply, realizing the triple guarantee of “two supply and one backup line” in the airshow center. At present, all loads of the air show are powered by two circuits. If any of these two circuits fails, it can be switched to the third circuit through the standby automatic switch. Even if both circuits fail at the same time, refer to the previous highest load and switch to the third circuit at the same time. The third circuit can also carry all loads and provide a reliable power supply.
