Problems solved by technology

However, the disadvantage of using flywheels for inertial energy storage is that since the flywheel is processed from a solid solid structure, the flywheel does not have the function of regulating fluid pressure during the process of energy storage or energy release

Abstract

The invention discloses an inertia energy storage device with a fluid pressure regulating function and an energy storage method thereof. The device comprises a vacuum container, a pressure regulationcontainer, a pressure transmission part, a kinetic energy recovery device and a hydraulic power generation device. The energy storage method comprises the following steps of providing a fluid, whereinthe fluid is liquid or compressed gas; accelerating the fluid after accelerating the fluid; when the fluid is decelerated, recovering deceleration kinetic energy of the fluid; and controlling pressure of the fluid from the first pressure to the second pressure according to the speed change rate and the motion state of the fluid during acceleration or deceleration of the fluid. According to the energy storage device, pressure regulation of the fluid can be carried out in an inertia energy storage process, and the fluid pressure energy after pressure regulation can be obtained.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and relates to an inertial energy storage device and method with fluid pressure regulating function. Background technique [0002] Inertial energy storage is the use of kinetic energy of objects in motion to store energy. At present, the method of inertial energy storage mainly uses the method of driving the flywheel to rotate at high speed for energy storage. The basic principle is to use the motor connected to the flywheel to drive the flywheel to accelerate the rotation, and convert the electrical energy into the rotational kinetic energy of the flywheel for storage. When energy needs to be released, the high-speed rotating flywheel is used to drive a generator mechanically connected to the flywheel to generate electricity, and the kinetic energy stored by the flywheel is converted into electrical energy for external output. Acceleration and deceleration of the flywheel enables energy ...
