Vertical-axis-type wind turbine equipped high-temperature superconducting generator with batch impregnation cooling structure using cryogen

A vertical axis wind turbine equipped with a high-temperature superconducting generator having a batch impregnation cooling structure using a cryogen, the vertical axis wind turbine comprising:

• the superconducting generator having a rotor core vertically standing up thereon, a rotor provided by locating a high-temperature superconducting field coil in a circumferential direction of the rotor core, a stator provided by locating a superconducting armature coil so as to be spaced apart from the rotor by a distance, and a cryostat adapted to accommodate the rotor core, the rotor, and the stator, as an integral module, therein and having a refrigerant circulation inlet pipe and a refrigerant circulation outlet pipe disposed on one side and another side of the cryostat to perform batch impregnation cooling for the superconducting generator by a circulation refrigerant introduced from a cryogenic cooling system;
• a tower assembly having a rotor shaft connected to a top end periphery of the rotor core so as to allow a top end portion thereof to extend to the outside of a top plate of the cryostat so that the rotor shaft is connected vertically to a main shaft having vertical blades by a shaft coupling the main shaft rotating inside a turbine tower through support bearings;
• and
• the cryogenic cooling system having a cooling chamber in which a circulation cooling pump is disposed adapted to supply a liquid refrigerant to the cryostat so that a vaporized gas refrigerant is collected, and a cryogen tank connected to one side of the cooling chamber and a helium compressor connected to another side of the cooling chamber, through respective supply lines.
