html On the morning of September 3, as the two switches of the Shanggong transformer were successfully closed, the "buzzing" sound of the main transformer of the Lingxian transformer sounded. The first traction station of the Hangzhou-Taiwan high-speed railway successfully completed power transmission and entered operation, opening 6 Tianjin invested in the external power supply project of five Hangtai-Taiwan high-speed railway traction stations, providing reliable power for the full opening of the Hangzhou-Taiwan high-speed railway at the end of the year. The Hangzhou-Taiwan High-speed Railway is an important part of the national coastal railway rapid passenger transport channel. It connects Hangzhou, Shaoxing and Taizhou. It starts from Hangzhou East Station in the north, uses the Hangzhou-Ningbo High-speed Railway to Shaoxing North Station, and then builds a new main line to Wenling Station in Taizhou City. The design speed is 350 kilometers per hour, and the total length of the line is about 266.9 kilometers, of which the new line is about 226.3 kilometers, with eight stations including Shaoxing North, Shangyu South, Shengzhou North, Shengzhou Xinchang, Tiantaishan, Linhai, Taizhou, and Wenling.
The 220 kV external power supply project of the Hangzhou-Taiwan Wenling Traction Station is an important part of ensuring the smooth operation of the Hangzhou-Taiwan High-speed Railway, and is also a provincial key project. "The high-speed rail train itself does not have a power supply. The power supply for the operation and control system comes from the traction station. The task of the power grid enterprise is to provide reliable power for the traction station. Therefore, during the construction of the high-speed rail, the power grid enterprise must build a network from the substation to the traction station. The power grid project transmits power from the substation to the traction station." Shen Hui, project manager of the Construction Department of the State Grid Taizhou Power Supply Company, likened the traction station to a "power bank". The smooth power delivery means that the traction station has been successfully used as a "power bank". Charging will provide sufficient power for the opening of high-speed rail in the future.
Hangtai Wenling Traction Station 220 kV external power supply project mainly includes the Shanggong-Wenling Traction Station double-circuit engineering dedicated line project and the Shanggong-Tangling and Shuguang-Longmen supporting projects. The line length is 68.6 kilometers and has a total of 114 base iron towers. It passes through Wenling In the six towns (streets) and railway new areas including Qiao, Daxi, Hengfeng, Zeguo, Taiping and Chengnan, 80% of the terrain involved in the project is mountainous, making construction difficult.
It is the Shanggong-Wenling traction station double-circuit engineering special line project that has been officially put into operation this time. The project started on November 24, 2020. Two single-circuit circuits are used to supply power to the Wenling traction station. The length of the new line is 18.098 kilometers, 54 new iron towers are built, and it crosses the Dashi first-class highway twice and 110 kV power lines six times. The entire dedicated line project involves the new railway area, 4 towns (subdistricts) and 9 villages. In view of the short construction period, repeated epidemics, complex adjustment of power grid operation methods and other difficulties, State Grid Taizhou Power Supply Company and other units scientifically coordinated personnel and reasonably arranged the construction organization plan. Strictly focus on construction safety and quality, and strengthen the control of the entire construction process through mechanization, informatization, intelligence and other means. As a local company, State Grid Wenling Power Supply Company has also mobilized its capable personnel to work with cadres from towns (streets) along the line to go to villages and households to do in-depth work with surrounding residents, and make every effort to handle land use policies and construction coordination along the project line. Convince the common people to "open the way" for high-speed rail.
The launch of the Hangtai Wenling traction station is the first time that the provincial and local dispatching levels have adopted a "standardized" model to complete the preparation of the startup plan. This model is also an important measure for Zhejiang Province's dispatching system to improve quality and efficiency and provide on-site services. After the
Hangzhou-Taiwan high-speed railway is put into operation, it will connect the Shanghai-Kunming, Shanghe-Hangzhou, Nanjing-Hangzhou, Hangzhou-Huangzhou and Hangzhou-Shenzhen high-speed railways, and be connected to the high-speed railway network in the Yangtze River Delta region, forming a core area of the Yangtze River Delta that radiates to southwestern Zhejiang and connects Hangzhou within Zhejiang Province. The fast connection between the urban area and the Wenzhou-Taiwan coastal urban agglomeration has shortened the railway travel time from Wenling to Hangzhou from about 2 hours to about 1 hour, which greatly facilitates travel for people along the line. At the same time, it will integrate Wenling into the Yangtze River Economic Belt and expand Zhejiang Province’s “1 The "hour traffic circle" scope is of great significance to help the Yangtze River Delta integrate higher-quality development.
