Problems solved by technology
[0005] However, the AC35KV / 10KV medium-voltage power supply ring network connected to the subway needs to increase the power supply capacity of the main substation of the subway line, and the power consumption of the substation needs to be increased separately from the medium-voltage grid of the urban power grid.
Both methods need to be reported to the State Grid for approval, occupying the total power supply capacity of the State Grid; adding traditional substations will increase land occupation and power supply equipment costs; adding traditional substations requires a huge amount of construction, increasing project investment, and even affecting existing facilities. wired operation

The invention relates to a rail transit section substation and a power supply section voltage stabilization control method. The section substation includes: a wiring system for connecting the section substation to a power grid; an energy storage system, which is connected to the wiring system , can store and release electric energy; control system, connected with wiring system and energy storage system, control system can send instructions to energy storage system to control energy storage system to charge and discharge; signal system, connected with control system, used for interval Communication between substations inside and between substations and external track lines. The substation in this section can be directly set up in the power supply section as a micro substation to solve the problem of low voltage of the power supply grid in the rail transit power supply section, especially in the long section. Large-scale construction, simple and easy, low cost.
Description
technical field [0001] The invention belongs to the technical field of rail transit power supply systems, and in particular relates to a rail transit substation and a voltage stabilization control method in a power supply interval. Background technique [0002] At present, with the continuous expansion of the domestic rail transit industry, more and more long sections or long ramp sections have appeared in the terrain that spans mountains, hills, rivers and oceans. For example, Shenzhen Metro Line 4 extends from the special zone to the second-line expansion area outside the special zone, and needs to cross the brain shell mountain; Chongqing Metro Line 1 extends from the urban area to the western university town, and needs to cross Gele Mountain; Shenzhen Metro Line 11, crosses The total length of the sea is 4175 meters; Qingdao Metro Line 1, the total length of the cross-sea section is about 8.1km; Wuhan Metro has planned a number of subway lines across the Yangtze River. ...
