Transient performance of a large scale wind turbine HTS synchronous generator under short circuit conditions

Abstract

In this paper, a precise study of transient behavior of a 10 MW class wind turbine high temperature superconducting (HTS) synchronous generator is carried out. The proposed generator is analyzed through d-q equivalent circuit model and the transient specification of the generator is studied. Then, the performance of the generator under sudden three phase short circuit fault condition is simulated using finite element method. Due to using a stainless steel damper screening to protect the HTS wires from armature transient magnetic field, proper performance of the proposed generator during fault condition is deduced. This paper deals with the proper design of the proposed large scale HTS wind turbine generator which can withstand under system fault conditions without any dangerous problems.
