The northern Shaanxi -Hubei ± 800 kV high -voltage DC transmission project is a "power highway" connecting the two provinces of Shaanxi and Hubei. It passes through the four provinces of Shaanxi, Shanxi, Henan, and Hubei, with a total length of 1127 kilometers. The project is delivered to the northern Shaanxi energy base and the Northwest Power Grid, which is connected to the Hubei Power Grid load center and Huazhong Power Grid. The project adopts my country's independent research and development and the world's leading high -voltage technology. The rated voltage is ± 800 kV and the rated capacity is 8 million kilowatts.

"The terminal of the Shaanxi Lake Project Wuhan Streaming Station is the first high -voltage stream station in Hubei Province. During the peak summer, the Shaanxi Lake project entered a high -power operating condition for the first time, with a maximum power of 4 million kilowatts. Even the economic and social development demand of the China -China Power Grid. "Hu Yuyang, the director of Wuhan Streaming Station, introduced," This annual maintenance aims to further improve the health level of equipment to ensure that the peak winter and the peak summer in the next half of the year and next year's peak summer equipment Stable operation, continue to make positive contributions to ensure the reliable supply of electricity, ensure national energy security, and help achieve carbon peaks, carbon neutrality and targets!

In order to ensure the high -quality development of this first inspection work, the State Grid Hubei DC Company strictly implemented the work deployment of the provincial companies, established an annual maintenance site project department, organized 1 overall plan for the first inspection, 49 sub -programs for maintenance projects, and the elimination of shortages 78 parts of the work, fully prepare for the first annual maintenance of Shaanxi Wu DC. Aiming at the huge scale of 769 construction units, 3 supervision units, and 38 equipment manufacturers of 8 construction units, the project department organized all the participants in the project to implement the health code, the itinerary code, and the 24 -hour kernel acid negative proof and other epidemic prevention. Control the inspection system and set up nucleic acid detection points at the entrance of the stream station to ensure the annual maintenance on -site epidemic prevention safety.
