Problems solved by technology

[0003] Existing electrolyzed water hydrogen production power systems, such as figure 1 As shown, AC / DC converters are usually used to supply power to multiple electrolyzers, so that these electrolyzers can achieve their own hydrogen production work; however, in practical applications, there may be differences between multiple electrolyzers due to differences in factory parameters, Factors such as inconsistent maintenance cycles or inconsistent parameters caused by different manufacturers produce uneven loads between electrolytic cells, forming a wooden barrel effect, and losing gas production

Abstract

According to the hydrogen production power supply system provided by the invention, the two-stage conversion module is arranged between the power supplies, and each output end of the second-stage conversion module is connected with the power supply end of each hydrogen production device in a one-to-one correspondence manner, so that independent power supply is provided for each hydrogen production device; and the loss of gas production rate caused by non-uniform load among the hydrogen production equipment is avoided. Moreover, the hydrogen production power supply system does not need to customize a frequency transformer to match the voltage in the prior art, so that the problem of large line loss can be avoided.

Description

technical field [0001] The invention relates to the technical field of new energy hydrogen production, in particular to a hydrogen production power supply system. Background technique [0002] As an important secondary energy source and industrial raw material, hydrogen plays an important role in industrial activities, and in the foreseeable future, hydrogen can expand its application scenarios in the field of people's livelihood. At present, the production of hydrogen is mainly the high-temperature reforming of fossil fuels, which will produce a large amount of CO 2 and pollutant discharge, which is not conducive to the realization of the national 30 / 60 target. The use of renewable energy for power generation-hydrogen production by electrolysis of water can achieve zero carbon emissions in the hydrogen production process, which is currently a technology that is vigorously developed in China and even in the world. [0003] Existing electrolyzed water hydrogen production po...
