Control method of hydrogen production purification system and related device

The invention provides a control method of a hydrogen production purification system and a related device. According to the invention, in the scene that the hydrogen production power of a hydrogen production unit is variable power, in order to avoid the influence of the power change of the hydrogen production power on a hydrogen purification unit, a purification inlet flow regulation value is determined based on the hydrogen production power of the hydrogen production unit, the buffer tank parameters of a buffer tank and the flow sampling value of hydrogen flowing into the hydrogen purification unit, and the hydrogen production purification system is controlled based on the purification inlet flow regulation value. Therefore, the control of the hydrogen production purification system is more suitable for the current variable power hydrogen production scene, the control accuracy of the hydrogen production purification system is higher, the hydrogen purification degree is better, and the hydrogen production req
