The three-core cable 1 is used to transmit electric power in the form of dc current and single-phase ac current. A first one of the conductive cores 2a is used to transmit dc current, while a second conductive core 2b is used to transmit the return dc current. The third conductive core 2c is used to transmit the single-phase ac current. The return ac current is transmitted along all three conductive outer sheaths 3a, 3b, 3c in parallel. The cable is used to transmit dc current from a wind turbine generator to a substation where it is converted to ac before connecting to the mains electricity grid. The ac current is used to power auxiliary circuitry of the wind turbine generator 5 when the output of the turbine generator 5 falls below a give value.

    Abstract: An off-grid wind turbine system comprising a wind turbine with an electric generator (G) for generating an initial electric power output (AC). An electrolyzer system with a hydrogen electrolyzer (ELT) located inside the nacelle or tower of the wind turbine, so as to generate hydrogen (H) by an electrolysis process. An electric converter system (CNV) serves to convert the initial electric power output (AC) into a DC electric power output (DC) dedicated for powering the electrolyzer (ELT). The produced hydrogen (H) is stored in a hydrogen storage tank (HTK), e.g. located adjacent to the wind turbine. Modules each comprising a converter and an electrolyzer may be stacked to provide the necessary capacity. In some embodiment, a synchronous generator excited by an external exciter (EXC) is used, and in some embodiments a hydraulic torque converter (HTC) is used. In some embodiments an AC to DC converter system involving transformer is used, while in other embodiments an intermediate DC to DC converter is used. By placing the electrolyzer (ELT) inside the wind turbine, a dedicated and compact wind turbine is provided which allows a rather simple and low cost wind turbine especially suited for storing energy in the form of hydrogen based on wind.
