The government has pushed ahead with the establishment of a connection system among education-task-qualification with regards to the promotion of engineering industry, but there has been a lack of pertinent data. In this regard, this study investigated the ways of connecting universities’ engineering education with Electrical Professional Engineer examination. The results show that the tendency of questions consists of 30[%] of transmission, 16[%] of basic theory, 14[%] of transformer, 14[%] of generation, 9[%] of new technology, 11[%] of other relevant fields. This study also presents a survey on the relationship between the engineer’s license and college curriculum. The curriculum of Electrical Engineering Department of a leading National University in Seoul is investigated in relation to the Examination. Some learning materials for successful completion of the university curriculum and acquisition of the Professional Engineer license are also recommended.

In This study, the design of a flux-switching type synchronous generator, using a superconducting wire rod, is discussed. As the existing superconducting synchronous generators generally have a form in which the superconducting field coil is placed in the rotor, they rotate along with the rotor in power generation. Thus, the cooling system for the cooling of the superconducting field coil and the exciting system for the exciting of the field coil contain complex structures, and there were multiple difficulties in terms of maintenance in addition. Since the flux-switching type superconducting synchronous generator proposed in this study has the superconducting field coil located in the stator, these problems can be solved, and the reliable operation of generator is possible even in the field of application in which the rotor has to rotate at a high speed. In this study, we designed a 10-MW flux-switching type superconducting synchronous generator and validated its performance, using a finite element analysis program.
