Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. The rail transportation energy storage system of the present invention includes high and low load fields 1, 2, transportation rail 3, traction / braking unit 5, high specific gravity load unit 6, power transmission line 4, storage rail 7, safety rail 8, grid access Module 10 and Control Center 9. like figure 1 As shown, the details are as follows.

[0016] 1) High and low load fields 1, 2: The load fields are used to store loads. The load field can be designed according to the terrain, including planar expansion or level expansion, and the high and low load fields 1 and 2 are connected with the main transportation track 3 through branch roads. The height difference between high and low load fields 1 and 2 is required to be higher than 100 meters, so that 1 ton of load can store energy greater than 0.27 (degree) KWh, thereby ensuring energy storage effi...

Abstract

The invention relates to an energy storage system based on rail transport. The energy storage system comprises high and low load fields for load parking, a transport track for load transportation, a power transmission line for providing traction power and transmission brake power generation, a traction/brake unit, a load unit, a storage track, a safety track, a control center and a power grid access module. In the invention, by means of combination of energy storage based on electrified track transport and brake power generation, in the case of excess electricity of the system, an electric traction locomotive carries heavy load from a low place to a high place so as to convert electric energy into potential energy for storage; and in the case of high demand of the electricity of the system, brake power generation is performed during the process that the electric locomotive carries the heavy load from the high place to the low place so as to convert the potential energy into the electric energy and transfer the electric energy to a power grid. The energy storage system has the advantages that energy with super-large and controllable volume and high density can be stored, the operation management method is simple, and the energy cycle efficiency is ultrahigh.

Description

technical field [0001] The invention relates to an energy storage power generation system utilizing rail transportation, belonging to the field of large-scale electric energy storage. Background technique [0002] The current power grid operation is facing challenges such as continuous increase in power load, increase in the proportion of intermittent energy access, and limited peak-shaving capabilities. Large-scale energy storage technology needs to be developed to help smooth intermittent power fluctuations, reduce load peak-to-valley differences, and enhance the system. Regulatory ability to ensure the safe operation of the power system, improve the system's utilization of renewable energy and reduce the dependence of economic development on the increasingly poor traditional fossil energy. [0003] At present, people have developed a variety of energy storage technologies, which can be divided into mechanical energy storage, electromagnetic energy storage, electrochemical...
