Abstract

The invention provides an optimization method for a transient process of alkaline water electrolysis hydrogen production equipment and a hydrogen production system. The optimization method comprises the following steps that: test parameters of the transient process of the hydrogen production equipment are input into a target digital twin model so as to optimize the transient process of the hydrogen production equipment, optimized control parameters are obtained and are used for guiding input parameters in the hydrogen production process. By implementing the method, the time of the starting process, especially a normal-temperature starting process, can be shortened, and the energy consumption of equipment is reduced, so that the actual hydrogen yield is increased.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a method for optimizing the transient process of alkaline water electrolysis hydrogen production equipment and a hydrogen production system. Background technique [0002] As a secondary energy source, hydrogen energy has multiple advantages such as diverse sources, zero terminal discharge, and wide range of uses. It is of great significance in ensuring national energy security and promoting the upgrading of the energy industry. With the maturity of technology and the sharp drop in cost, hydrogen energy is ushering in a period of strategic opportunities for rapid development. Among the mature electrolytic water hydrogen production technologies, the alkaline electrolytic water hydrogen production technology is relatively mature, the process is relatively simple, and the cost is relatively low, but the bottleneck is the relatively low working current density (less than 0...
