High speed railway Huai'an east station main power supply point Gaogang 110kV substation put into operation

"Report to the dispatching desk that the fifth charging of No. 2 transformer of Gaogang substation is successful and all loads are connected normally." At 0:52 on November 30, the 110kV substation of Gaogang was successfully put into operation, and it became the main power supply of the East Huai'an station of the high-speed railway, and was used as a backup for each other with the 220kV substation of Tieyun, which together provided a strong guarantee for the operation of the high-speed railway of Huai'an. The 110kV substation of

high port is located in the new high speed railway area of Huai'an City, covering an area of 6400 square meters. The substation is an intelligent indoor substation. In this phase, two 50MVA main transformers, two 110kV incoming lines and 24 10kV outgoing lines will be built. As the main power supply point of High-speed Railway East Huai'an station, the 2-circuit 10kV outgoing line from Gaogang substation to High-speed Railway East Huai'an station can meet the load demand of 12300kva of high-speed railway station.

the power transmission and transformation line project of this Gaogang substation mainly includes Tieyun Gaogang 110kV line project, Huanggang Gaogang 110kV line project and Huanggang banzha line Huanggang side to Tieyun substation 110kV line project. The total length of the construction line is about 8.328km.

"the project started at the beginning of February this year, only lasted for 9 months, which is 4 months shorter than the normal substation construction period of 13 months. In order to speed up the Huai'an high-speed railway, the power supply company constantly studies and refines the adjustment plan, the power supply staff work overtime, play the spirit of hard work, overcome many difficulties, complete the project construction in advance, and provide power support for the future operation of the high-speed railway station. " Wang Naizhi, project site director of the power supply company, said. It is understood that in the middle of December, xusuhuai salt and lianhuaiyang (donghuai section) railways will be officially opened to traffic. Since then, Huai'an has officially entered the era of high-speed rail cars. This is of great significance to accelerate the integration of Northern Jiangsu into the Yangtze River Delta rapid traffic circle and urban economic circle, to revitalize the rural economy, and to achieve higher quality development of Yangtze River Delta integration. The Huaian east station of Lianzhen and xusu high-speed railway, which will be put into operation soon, is one of the four high-speed railway hubs in the province, and shoulders the important mission of supporting Huaian to build an important central city in Northern Jiangsu. Since the construction of the project, the power supply company has devoted itself to the high-speed rail power access work to meet the power demand of the high-speed rail project construction in an all-round way. Before

, in order to meet the needs of Lianzhen railway construction, the company completed the supporting 220 kV line project and 220 kV line relocation project of Huaian East traction station of lianhuaiyang railway from April to August 2019. Among them, the total length of the construction line of the supporting 220 kV line project of Huai'an East traction station is 2.2km, with 14 iron towers in total. The construction team has completed the basic construction, high-speed construction, high-speed railway construction, tension defense line and parameter test, and prepared for power supply guarantee for the operation of the railway special line. In the relocation project of 220kV line, the original 220kV line is erected with four circuits on the same tower. After reconstruction, it is divided into two 220kV double circuit lines to ensure the safe operation of the passing trains.
