Problems solved by technology

However, electromagnetic levitation technology consumes a lot of power, and the sensors and controllers are bulky, expensive, complicated to control, and low in reliability; superconducting levitation requires refrigeration equipment, so it also has large volume, high energy consumption, complex structure, and high cost. and other shortcomings
When maglev technology is applied to maglev mechanical energy storage, the shortcomings of the above two maglev technologies become more obvious

Abstract

A circular track magnetic levitation vehicle energy storage system comprises a track (10), a vehicle (20), a current conversion device (30) and a track wall (5). Vehicle-mounted permanent magnet blocks (1) and a vehicle drive magnetic pole (2) are fixed to the vehicle (20); and a track drive coil (3) and track permanent magnet blocks (4) are fixed to the track (10). When the circular track magnetic levitation vehicle energy storage system needs to store energy, the current conversion device (30) absorbs energy from a power grid, a moor system composed of the vehicle drive magnetic pole (2) andthe track drive coil (3) drives the vehicle (20) to rotate at an accelerated speed, and the stored kinetic energy is increased; and when the circular track magnetic levitation vehicle energy storagesystem needs to release the energy, the motor system works in an electric generator state, and generated electric energy is fed back to the power grid through the current conversion device (30). Levitation and guidance of the vehicle (20) are achieved through the vehicle-mounted permanent magnet blocks (1) and the track permanent magnet blocks (4), and friction between the vehicle (20) and the track (10) is reduced.

Description

technical field [0001] The invention relates to an energy storage system for a circular track magnetic levitation vehicle. Background technique [0002] The magnetic levitation mechanical energy storage system is a kind of mechanical energy storage method. It is an energy storage device based on electromechanical energy conversion. It uses the kinetic energy of a high-speed moving vehicle to store energy. When the grid needs energy, the moving vehicle decelerates and releases the stored energy. With the large-scale development and utilization of new energy sources such as wind energy and solar energy, there is an urgent need for large-scale energy storage. However, existing energy storage methods, such as battery energy storage, usually have disadvantages such as low efficiency, high cost, unfriendly to the environment, and slow response. [0003] In addition, in the magnetic levitation train technology, in order to use the magnetic field force to levitate the moving train...
