A batch of major projects in transportation, energy and other fields have made phased progress in construction, empowering high-quality economic and social development. Haba | Railway | Major Projects
CCTV, Beijing, July 9th, according to the News and Newspaper Digest of China Central Radio and Television, a number of major projects in the fields of transportation and energy have ushered in phased progress recently, effectively empowering the economy and society. High-quality development.
The key control project of the Yunnan Lijiang Shangri La Railway on the Yunnan Tibet Railway - the construction of the Haba Snow Mountain Tunnel track bed was completed on the 8th, and it is ready for track laying. This marks the completion of the Haba Snow Mountain Tunnel, the last tunnel on the entire Lixiang Railway, after 9 years of intensive construction.
The 9523 meter long Haba Snow Mountain Tunnel is located in the Diqing Tibetan Autonomous Prefecture of Yunnan Province. It is situated in the northwest longitudinal valley of the Hengduan Mountains on the Qinghai Tibet Plateau. Due to the long-term activity of multiple fault zones, problems such as landslides, karst, and large deformation of soft rocks are extremely prominent.
Huo Erlun, the project leader of the Haba Snow Mountain Tunnel: We will complete the construction of the ballastless track bed on the 8th. After 7 days, when the strength of the ballastless track bed reaches the standard value, we can install the long rail. The long rail can be installed in the Haba Snow Mountain Tunnel within two days.
According to the plan, the Lixiang Railway will be completed and opened to traffic within this year, ending the history of no railway access in Diqing Tibetan Autonomous Prefecture, Yunnan Province, and filling the gaps in railway network and transportation services in the northwest region of Yunnan.
The world's largest single unit salt light complementary photovoltaic project - Huadian Tianjin Haijing 1000 MW "salt light complementary" photovoltaic project has recently been officially put into operation. The project links the existing salt industry and aquaculture industry, forming a three-dimensional circular ecological model of "water photovoltaic power generation, surface evaporation brine production, and underwater aquaculture" while ensuring that the land nature remains unchanged, the profits from salt fields do not decrease, and the ecological environment remains unchanged.
Tong Wei, the person in charge of Huadian Tianjin Haijing Photovoltaic Project of China Construction Third Bureau, said that after the project is put into operation, it will further promote the transformation of the green energy structure in North China, saving about 500000 tons of standard coal for power generation and reducing about 1.25 million tons of carbon dioxide emissions annually.
The first 20 kV AC flexible interconnection device in China has been officially put into operation at the 110 kV Wushan Substation located in Heping Town, Changxing County, Huzhou City, Zhejiang Province. Wushan Substation is located in Changxing Heping Industrial Park, with a large number of industrial users in the area. The main transformer and line load are heavy, and users are extremely sensitive to voltage. In the past, maintenance of substations could only be carried out through power outage and cold shutdown. Now, the 20 kV AC flexible interconnection device can achieve "zero impact closing", balance power supply and consumption on site, and users no longer have the trouble of power outage. Effectively improving the carrying capacity and reliability of regional distribution networks.
Wan Lijian, a staff member of State Grid Changxing County Power Supply Company: With the use of flexible interconnection devices, some heavy loads from Wushan Substation can be reasonably distributed to relatively light load transformers, thus achieving load balance.
