The first traction station of Xuancheng section of Shanghe Hangzhou high speed railway successfully delivers power
On January 8, the 220kV Zongji 2vq0 line was successfully impacted and the 220kV Jichuan traction station was powered on, providing strong support for the live debugging of the Xuancheng section of the Shanghe Hangzhou high speed railway. A 6031 a 6031 220 kV Jichuan traction station is located in the southeast high speed rail planning area of Xuancheng City. The external power supply project of the traction station was started in August 2016, mainly involving the construction of four 220 kV high-voltage transmission lines with a total length of 87.4 km and the expansion and reconstruction of two bays of 220 kV zonghanling substation. The project passes through 3 districts and counties of Xuancheng City, including Xuanzhou District, Langxi county and Guangde City, crossing 8 traffic facilities such as high-speed railway, high-speed and navigable river, demolishing 22 old towers and erecting 70 new ones. The project construction time is tight, the task is heavy, the operation point is wide, the external environment is complex.
in order to fully ensure the high-quality and efficient completion of the supporting power supply project of Xuancheng section of Shanghe Hangzhou high speed railway, Xuancheng Power Supply Company of State Grid has formulated a dedicated power supply service plan. At present, all supporting power supply projects of Xuancheng section of Shanghe Hangzhou high-speed railway have been completed in advance and have power transmission conditions. In order to cooperate with the early operation of Shanghe Hangzhou high speed railway, four transmission lines of two Shanghe Hangzhou high speed railway traction stations in Xuancheng are divided into two stages. In the first stage, each high-speed railway traction station will be equipped with one line for power transmission, so as to meet the preliminary joint commissioning and trial power conditions of high-speed railway traction station. The second stage is to complete the start-up and transmission of the other two supporting transmission lines before the official operation of the high-speed railway, so as to ensure the safe and stable operation of the high-speed railway.
according to the plan, by the end of April 2020, all high-speed rail power supply projects in Xuancheng will be fully powered to realize dual power supply. After the two traction substations in Jichuan and Xiangcun have been put into operation successfully, they will meet the conditions for the opening of the whole line of Shanghe Hangzhou high speed railway and further optimize the Xuancheng Power grid structure. It is expected that in June 2020, the south section of Shanghe Hangzhou high speed railway (from Hefei Station to Huzhou station) will be officially put into operation, completely ending the lack of high-speed railway in Xuancheng City.
