High Temperature Superconducting (HTS) generator for a large-scale wind power generation system draws much attention as a contemporary research item. Metal-Insulation (MI) technique greatly enhanced the thermal stability of the coil without requiring complicated protection against quenching because quench currents are bypassed through the turn-to-turn contacts, ultimately improving the...

The superconducting synchronous generator is one of the breakthrough elements for direct-drive wind turbine because it is light and small. Normally the superconducting one has copper armature windings in the stator and superconducting field windings on the rotor. The electrical frequency of the output voltage of the direct-drive generator is very low, so the total length of the armature...

Offshore wind energy is going to take the dominated place in renewable energy due to it abundant and steady wind resource. To reduce the levelized cost of energy, the large power rate, even above 10 MW, wind generators are preferred for offshore wind farms. Compared with conventional wind generator such as induction generators and permanent magnet generators, high temperature superconducting...

Nowadays, wind energy is developing rapidly as it is clean and renewable and the offshore wind energy is one of the most popular ones for its abundant source. To avoid frequent maintenance of the offshore wind turbine system, a large direct-drive generator is needed. Due to the advantages of the higher magnetic field in the high temperature superconducting (HTS) machine compared to that of the...

Fully-superconducting generators with compactness and lightweight are promising candidates for direct-drive multi-mega-watt offshore wind turbines due to its high current density properties. The compactness and lightweight design should bring about the cost reduction of nacelles, towers and foundations. Furthermore, high-performance REBa2Cu3Oy (REBCO: RE = rare earth) tapes and the reduction...

A high torque density enables high temperature superconducting (HTS) generators to be a strong candidate for lightweight, efficient and cost-effective large direct-drive (DD) wind turbines, especially for the next-generation floating wind turbines where a less top head mass is appreciated.
