Supercritical carbon dioxide energy storage control device and flow adjusting method

The invention discloses a supercritical carbon dioxide energy storage control device and a flow regulation method, and the control device comprises a control system, a flow meter, a pressure sensor, a high-pressure gas storage, a buffer tank, an air sensor and an expansion machine, the control system controls the inflation process of the high-pressure gas storage and the gas release process of the buffer tank according to gas parameters detected by the flow meter, the pressure sensor and the air sensor. The flow adjusting method comprises the steps that the control system compares detected gas parameters with gas parameters in the high-pressure gas storage and the buffer tank and controls the inflation process of the high-pressure gas storage and the gas release process of the buffer tank by controlling opening and closing of the input and output control valve. The effect of accurately controlling the inlet pressure and flow of the expansion machine can be achieved, the problem of sliding pressure of supercri
