Abstract: Provided is a testing apparatus for an active current control-type non-contact superconductive exciter having a hybrid magnet installed therein, and a high-temperature superconductive rotating machine using same. Provided is principally characterized by having a hybrid magnet, in a module form, in which a permanent magnet, a DC electromagnet and an AC electromagnet are used together, wherein the hybrid magnet is set in a plurality along the circumferential direction of a ring-shaped iron stator, is formed to correspond to the outer side of a rotor, having a high-temperature superconductive tape (or a second-generation high-temperature superconductive wire), of a non-contact superconductive exciter, and thus enables a selected operation (charging, discharging and the like) before and after rotation of a driving motor.

Abstract: The present invention relates to a high-temperature superconducting rotating machine system equipped with a fixed type cryostat and a vaporized cryogen re-use cooling structure.
The high-temperature superconducting rotating machine system equipped with a fixed type cryostat and a vaporized cryogen re-use cooling structure is configured to allow the cryostat as an immovable structure (fixed structure) where a liquid refrigerant is normally stored to be disposed in a rotor part where a high-temperature superconducting field core and a direct current power generator for a non-contact type exciter are located, so that a manufacturing and constructing structure becomes more simplified when compared with an existing cryogenic cooling structure (wherein a special and complicated cooling structure is needed to supply a cryogen to a high-temperature superconducting field coil rotating at a given speed) upon cryogenic cooling, thereby greatly improving the operation reliability, maintainability, and profitability of the rotating machine system.-

Abstract: The present invention relates to a vertical axis wind turbine equipped with a high-temperature superconducting generator having a batch impregnation cooling structure.
The vertical axis wind turbine is configured to allow the superconducting generator and accessory devices (a cooling system, a power conversion system, etc.) to be located under a turbine tower, whereas allowing only a rotary body with vertical blades to be located on the upper portion of the turbine tower, unlike a conventional horizontal axis wind turbine, thereby remarkably reducing a top-head weight of the wind turbine, greatly decreasing installation and maintenance costs, removing technical difficulties in large scale construction, and allowing a center of weight to move to a portion under the turbine tower so that if the vertical axis wind turbine is applied for floating offshore wind power generation, it advantageously ensures the miniaturization of a floating body and the stability of a floating posture.
