New energy off-grid hydrogen production system and method

The invention provides a new energy off-grid hydrogen production system and method.The system comprises a series connection boosting module, a direct current transmission module and a hydrogen production module, the series connection boosting module is used for conducting confluence boosting on n paths of first direct current output by a new energy field station to form second direct current; the direct current transmission module is used for directly transmitting the second direct current to the hydrogen production module; and the hydrogen production module is used for reducing the voltage of the transmitted second direct current so that the electrolytic bath can produce hydrogen. The cost of hydrogen production equipment can be effectively reduced. 本发明提供了一种新能源离网制氢系统及方法，所述系统包括串联升压模块、直流传输模块、制氢模块，其中，所述串联升压模块，用于将新能源场站输出的n路第一直流电进行汇流升压，形成第二直流电；直流传输模块，用于直接将第二直流电传输至制氢模块；所述制氢模块，用于将传输的第二直流电进行降压，以供电解槽进行制氢。本发明可有效降低制氢设备成本。
