A wind turbine generator includes a stator having a plurality of high-temperature superconducting coils. A current is driven through the high-temperature superconducting coils to produce a magnetic field. A rotor comprising one or more phase coils is physically coupled to a wind turbine. As the wind turbine turns the rotor, current is induced in the one or more phase coils to produce electrical power. The phase coils may include conductive material, superconducting material, and/or high-temperature superconducting material.

Wind turbine generator with high temperature superconducting elements

Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.

Grooved, stacked-plate superconducting magnets and electrically conductive terminal blocks and related construction techniques

Described is a partitioned cable joint comprising a plurality of physically distributed joint elements with the plurality of joint elements taken together defining a joint length. Joint elements may have a first mounting region having a shape selected to accept one petal of superconducting cable and a second mounting region having a shape selected to accept one petal of a second conductor.
