Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, it is a schematic diagram of the structural principle of a solar power generation system with a superconducting magnetic energy storage device for railway traction power supply, which mainly consists of solar cells, a superconducting magnetic energy storage system, a traction common power supply system, and trains. Among them, the electric energy provided by the solar cell is stored by the superconducting magnetic energy storage system, and is provided to the train after being converted by the converter and transformer when the train needs it. Therefore, the superconducting magnetic energy storage part is the key to the design of the entire system.

Abstract

The present invention discloses a superconducting magnetic energy storage solar energy power supply scheme applied to railway traction power supply. In a distributed solar energy power supply railway traction power supply system formed by a solar cell module, a superconducting energy storage device and a power transmission device, electric energy stored in the superconducting magnetic energy storage device and generated by renewable energy sources directly supplies traction power for an electric locomotive. According to the invention, electric energy may be generated through solar energy and then is stored without loss through a superconducting magnetic energy storage device, and power is supplied to locomotives along the line through an alternating-current traction power supply system. The whole system provided by the invention may be taken as a distributed generation system and may reliably supply power for electric locomotives with environmental protection.

Description

technical field [0001] The invention belongs to the technical field of railway traction power supply, in particular to a system for applying solar power generation with a superconducting magnetic energy storage device to provide traction power for electric locomotives. Background technique [0002] The energy radiated by the sun to the earth's surface in a year is equivalent to tens of thousands of times the energy provided by various energy sources available to mankind in the same period, making it the renewable energy source with the most application potential. my country's solar energy resources are mainly distributed at 22° to 35° north latitude, and the Qinghai-Tibet Plateau is the center of the highest value of resources. At the same time, the distribution of railways in Tibet is sparse, and the number of trains is relatively small. The long-distance traction power supply system consumes consumables and labor, and at the same time, the local area is not effectively used...
