Title:
LIQUID LEVEL BALANCE CONTROL METHOD FOR HYDROGEN PRODUCTION SYSTEM AND HYDROGEN PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/020265
Kind Code:
A1
Abstract:
The present application provides a liquid level balance control method for a hydrogen production system and a hydrogen production system, which are applied to the technical field of hydrogen preparation. The method comprises: after obtaining a parameter value variation of a target electrical parameter and a parameter difference of target state parameters of a hydrogen separator and an oxygen separator, according to the parameter value variation, determining a first adjustment amount; on the basis of the first adjustment amount and the obtained parameter difference, further determining a target adjustment amount; and finally, according to the target adjustment amount, adjusting the liquid level of the hydrogen separator and/or the oxygen separator. In the present invention, the target electrical parameter is related to the hydrogen production power of the hydrogen production system. Since fluctuation of the hydrogen production power directly affects the change in liquid level of the hydrogen separator and the oxygen separator, and the change in liquid level occurs after the fluctuation of the hydrogen production power, the adjustment amount can thus be determined in advance before the hydrogen production power finally impacts liquid level deviation, response time of liquid level adjustment is shorter, liquid level balance control efficiency is effectively improved, liquid level fluctuation is smaller, and the liquid level balance control effect is improved.
