Patent ID: 7667343

Claim:
A wind turbine-driven hydrogen production system having a wind turbine, installed independent of an electric power system and connected to an electrolytic hydrogen production system, to produce an output power to said electrolytic hydrogen production system for hydrogen production, said wind turbine-driven hydrogen production system comprising: means for generating a current command value based on amounts of a pressure of hydrogen and a temperature within said electrolytic hydrogen production system, a rotational speed of said wind turbine of said wind turbine-driven hydrogen production system, and a pitch angle of said wind turbine used to control the rotational speed of said wind turbine of said wind turbine-driven hydrogen production system, the pitch angle of said wind turbine being arranged to be determined in accordance with an average wind speed of said wind turbine and a maximum electric power having been calculated based on the pressure and the temperature within said wind turbine-driven hydrogen production system; and means for varying an electrical current supplied to said electrolytic hydrogen production system in accordance with the current command value so as to suppress variations in the rotational speed of said wind turbine.
