Technical issue of 10MW class superconducting wind power generator

Prof. Minwon Park
Changwon National University, Korea

Abstract

Wind power is considered one of the major renewable energy resources to replace fossil fuels for the generation of electricity. In order to enhance the economical and electrical efficiency of wind power generation system (WPGS), researchers have been trying to develop much larger WPGS. Also a superconducting synchronous generator (SCSG) has been suggested to reduce the weight and size of generator for high-capacity WPGS.
The main objectives of this talk are to discuss the technical issue of 10 MW class SCSGs with different drive-trains for a WPGS and the comparison of the generator designs considering mainly weight and size of generator. Generally, the total weight of blade and nacelle of the 10MW class PMSG generator is expected as around 1,000 ton if being manufactured. It is the significant factor not to achieve to 10MW class WPGS with technologies of the conventional wind power generation. In this talk how much SCSG can reduce the weight and size comparing with the conventional generators will be mainly discussed considering various types of drive trains.
Various drive trains have been developed for the effective transfer of kinetic energy from the wind turbine to the generator. Drive trains can be classified according to their gearboxes (geared or gearless). The structure and operational efficiency of generator differ according to the type of drive train. Therefore, a comprehensive study on the design characteristics and efficiencies of the different types of drive trains for 10 MW class WPGSs with SCSG is necessary.
