Off-grid operation type compressed air energy storage test platform and operation method

Abstract

The invention discloses an off-grid operation type compressed air energy storage test platform and an operation method. The off-grid operation type compressed air energy storage test platform comprises an air compressor and a motor, the motor is connected with the air compressor through a belt, and an air turbine is connected with a generator through a belt or a shaft; an inlet of the air compressor is connected with the atmosphere, an outlet of the air compressor is connected with a check valve through a pipeline, the check valve is connected with a high-pressure air storage tank and a regulating valve through three-way valve pipelines, the regulating valve is connected with an inlet of the air turbine through a pipeline, and an outlet of the air turbine is connected with the atmosphere;and the power output end of the generator is connected with one or more groups of high-power bulbs. The technical problems that in the prior art, a compressed air energy storage test platform needs tobe connected into a power grid for test operation, due to large change of test working conditions and many sudden abnormal conditions, safe operation of the power grid is prone to being disturbed when the platform is connected into the power grid for operation, and potential safety hazards are caused are solved.

Description

technical field [0001] The invention belongs to the technical field of compressed air energy storage, and in particular relates to an off-grid compressed air energy storage test platform and an operation method. Background technique [0002] With the rapid development of the electric power industry, large-scale new energy is integrated into the power grid on the basis of traditional energy, and the intermittent and fluctuating nature of new energy power generation requires a large amount of energy storage to stabilize and ensure the consumption of new energy. Compressed air energy storage has the characteristics of large capacity, low pollution, and long life, and is one of the energy storage types with the most room for development. [0003] The compressed air energy storage system uses a compressor to pressurize the air to a higher pressure during the low electricity consumption, and then cools and stores it in the air storage tank to consume electric energy. The air expa...
