Abstract

The invention discloses a hydrogen fuel cell system air compressor control system and method and a storage medium, wherein the hydrogen fuel cell system air compressor control system comprises an air compressor, an air compressor control unit, a circuit fluctuation suppression circuit, a flow measurement unit and a general control unit; the air compressor is provided with an air inlet and an air outlet; the air compressor control unit is connected with the air compressor; the circuit fluctuation suppression circuit is connected with an external power supply and the air compressor control unit and is used for suppressing circuit impact generated during operation of the air compressor; the flow measurement unit is used for acquiring an air flow measurement value at the air inlet; and the general control unit is used for adjusting the operation states of the air compressor under different air flow measurement values through the flow measurement unit and the air compressor control unit, and suppressing current impact and circuit impact generated in the operation of the air compressor through the circuit fluctuation suppression circuit. By means of the system, the air compressor can be controlled to operate after the rotating speed is changed according to the real-time air flow measurement value, and meanwhile it can be guaranteed that circuit impact is suppressed when the rotating speed of the air compressor is rapidly adjusted.

Description

technical field [0001] The invention belongs to the field of air compressor control, and in particular relates to a hydrogen fuel cell system air compressor control system, method and storage medium. Background technique [0002] In the current hydrogen fuel cell system, in order to obtain a stable air flow and pressure, a calibration control that correlates the stack current with the speed of the air compressor is usually used. Controlling the air compressor in this way can make the air compressor run stably at the same speed under the same current, and reduce the fluctuation of air flow and power supply current of the air compressor. However, this control method is greatly affected by the environment. Usually, different current-speed curves are calibrated by ambient temperature and pressure. Not only is the calibration cumbersome, but the air flow is still affected by environmental factors, which may cause insufficient or excessive air supply to the stack. . However, if ...
