Resumen

LEAO RODRIGUES, A. Superconducting Wind Synchronous Generator. Inf. tecnol. [online]. 2010, vol.21, n.2, pp.37-44. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642010000200006.

This paper presents the properties of high temperature superconductor (HTS) materials in the construction of electrical machines. A disc type configuration synchronous generator with high specific power for future wind power applications is described. The generator is excited by means blocks of HTS ceramic materials. The mechanism to trap the magnetic flux in HTS blocks is explained. To decrease the weight of the generator on the top of the tower, the cryogenic system used consists of a liquid nitrogen storage container located on the ground to reduce weight on the tower. A flux plot per two poles of the machine calculated using the finite element method is presented and the flux density distribution in the air gap of the superconducting disc generator is also displayed. A high efficiency wind park with this type of generators is proposed.

Palabras clave : high temperature superconductor materials; wind synchronous generators; wind park.
