Short-circuit characteristics of superconducting permanent magnet generators for 10 MW wind turbines

Superconducting permanent magnet generators (SCPMGs) are a potential candidate for 10 MW direct-drive wind turbine applications. This paper presents two 10 MW SCPMG designs using MgB<sub>2</sub> cables for the armature winding and investigates the short-circuit characteristics of the designed SCPMGs. The first part...

Performance of Multi-Layer and Stator-Shifting Fractional-Slot Concentrated Windings for Superconducting Wind Turbine Generators under Normal and Short-Circuit Operation Conditions

High temperature superconducting (HTS) generators are being considered for large offshore direct-drive (DD) wind turbines as they are expected to be lightweight and compact. However, short circuit torques of an HTS generator with integral-slot distributed windings (ISDWs) are too high for wind turbine constructions, mainly due to the large...

Design Considerations and Short-Circuit Characteristics of Fully Superconducting Wind Turbine Generators

Compared with partially superconducting generators, fully superconducting generators (F-SCGs) can further increase the torque density in large direct-drive wind turbine applications. Design trends of F-SCGs intend to increase the electrical loading by applying superconducting wires and boost the current density in the armature winding to meet...

Increasing the Feasibility of Superconducting Generators for 10 MW Direct-Drive Wind Turbines

In recent years, superconducting synchronous generators (SCSGs) have been proposed as an alternative to permanent magnet synchronous generators (PMSGs). They are expected to reduce the top head mass and the nacelle size for such large wind turbines. In 2012, the INNWIND.EU project initiated this research to investigate SCSGs for 10-20MWdirect...

Modelling and Transient Analysis of a 10 MW Superconducting Wind Turbine Generator

The number of installed wind turbines is growing every year as the need for energy increases in an exponential manner. As the wind turbines are trying to fulfill these requirements, the demand for output power from each individual turbine is increasing as well. Although this is great, implementation of new technologies such as direct drive...
