WIPO Patent Application WO/2023/033407
Kind Code:

Abstract:
The present invention relates to a vertical-axis-type wind turbine comprising a high-temperature superconducting generator having a mass-impregnation cooling structure for a cryogenic coolant. The technical subject matter of the present invention, compared to that of a conventional horizontal axis-type turbine, is characterized in that attached devices (a cooling device and a power conversion device) including a generator are provided at the lower part of a turbine tower, and only a rotating body including vertical blades is disposed at the upper part of the turbine tower, so that the weight of a top-head of a wind turbine can be remarkably reduced, and thus installation costs and maintenance and repair costs are greatly reduced and technical difficulties in large-scale construction (a conventional horizontal axis-type wind turbine structure is an airfoil-shaped blade structure, and is difficult to enlarge due to load concentration caused by a one-point support) are solved, and, specifically, the size of a floating body can be reduced and floating position stability is advantageously ensured during application to floating-type offshore wind power generation since the wind turbine is formed as a structure having a center of gravity that moves toward the lower part of the tower. In addition, the present invention mass-impregnates the superconducting generator with a liquid coolant in a cryogenic cooling tank so that a vacuum insulation structure for the cryogenic cooling tank, which maintains ultralow temperature, can be minimized, and can easily apply, through the comprehensiveness and simplicity of a cooling structure, a fully superconducting structure for superconducting an armature winding positioned at a stator of the superconducting generator.
