The first 220 kV underground power station in Central China is put into production and delivery

At 9:30 am on September 29th, 220 kV Xudong underground substation located in the core area of ​​Wuchang Binjiang Business District, Wuchang's Wuchang Binjiang Business District was put into production. The station is the first 220 kV of the 220 kV of the new generation of intelligent transformation power stations. It adopts the model of joint investment and construction of the power grid and the government and Greenland Group. It is also the first 220 kV substation built in the Wuhan municipal administrative enterprise cooperation model.

According to Yiyu, a 220 kV Xu Dong underground power station project manager and the 5th level staff of the National Grid Wuhan Power Supply Company Project Management Center, the overall building of the station is divided into three underground floors, one floor on the ground, the depth of the foundation pit excavation is 20 meters, the building The underground area is 9720 square meters, the substation covers an area of ​​3,300 square meters, the ground area is 772 square meters, and the new cable tunnel is 7.6 kilometers in length. A number of technologies such as miniaturized electrical equipment, main transformer water cooling systems, intelligent inspection, one -click smooth control, and intelligent fire extinguishing are all leading in China, and China is the first in China.

220 kV Xu Dong underground substation fully focuses on the concept of environmental friendship. The ground building of the substation is concentrated, uniformly incorporated into the green land international financial city landscape system, and organically integrates with urban buildings. Select small -scale equipment to effectively save the area of ​​land use, and go deep into urban load centers to play a role. Arrange all the main equipment on the ground to reduce noise. The substation is set in and qualified to make full cable laying to fully release the urban space.

After the station is put into operation, it will meet the power supply needs of the core area of ​​the Wuchang Binjiang Business District in the next 15 years. At the same time, the power supply range of the station will be extended to the Yangtze River in the north, the south to Qinyuan Road, Youyi Road, and Jiyuqiao. In this area, the reliability of power supply is fully improved in the central urban area of ​​Wuchang. Its construction model and construction concept will also become a new model for government -enterprise cooperation and green construction.

A reporter from the Yangtze River Daily visited the underground substation of Xu Dong and found that on the ground floor, the station is like an ordinary building, which is integrated with the surrounding business district environment; the underground is divided into three floors. , Battery, the second floor of the underground is the main part room, 10 kV electric equipment room, etc., and the third floor of the underground is the cable mezzanine.

"Xu Dong's underground substation is constructed according to the concept of" unmanned duty '' full intelligence '. There are spherical cameras on all parts of the entire station, which can be clear at a glance in all scenes in the background. " The data above can be transferred to the background to improve work efficiency. "

The reporter saw in the 10 kV power distribution device room that the entire area is equipped with a sliding rail, and the rails are equipped with intelligent inspection robots. They can control the running state in all -round control through background control. "After setting up cyclical inspection tasks for the robot in advance, it can work by itself." Yi said.

Yi also introduced that the groundwater and cold transformer of the station focuses on 120 tons, while the gap between the second floor of the ground floor is 20 meters. "There are 3 main transformers in total, and it needs to be stable and not bumped. Therefore, a crawler is lifted."

The power supply capacity of Wuhan Grid increased by more than 12% year -on -year

At the end of 2019, Wuhan opened the construction of first -class urban power grids to accelerate the construction of national central cities. Wuhan Municipal People's Government and State Grid Hubei Electric Power Integration, the nation's first power grid construction model of power grid construction in the country.

This year, the State Grid Wuhan Power Supply Company launched the "Power Grid Construction Conference" to accelerate the construction of Wuhan's first -class urban power grid. From January to September, 14 power transmission and transformation projects have been completed, which has increased 1.77 million kV power to Wuhan Power Grid. Before the end of the year, 11 power transmission and transformation projects will also be completed, with a new power supply capacity of 2.28 million kVA. It is expected that the new transformer capacity will reach 4.05 million kV in 2022. The power supply capacity of Wuhan Grid increased by more than 12%year -on -year. At present, the power supply capacity of the Wuhan Donghu New Technology Development Zone is 4.4 million kVA, which means that this year Wuhan Power Grid will "reconstruct" a Optical Valley power grid capacity.

According to the State Grid Wuhan Power Supply Company, in accordance with the idea of ​​"electricity such as electricity, etc.", Wuhan Power Grid anchor the "33621" development goal, and uses 3 years to promote 3 special high -voltage cities and 3 ultra -high pressure into the city project project By 2025, the total capacity of Wuhan Power Grid will increase from 36.77 million kV to 60 million kVA, and the cumulative production of more than 100 parts of the substation will meet the needs of the high -quality development of Wuhan Power Grid and the high -speed economic development of Wuhan.
