This paper presents an effective simulation method for the high temperature superconducting(HTS) transformer using components developed in the PSCAD/ EMTDC. So far, there were numerical modeling and designs for conventional transformers for various applications. Recently, the interest and the Research & Development in superconducting technology and devices such as superconducting generator, motor, cable, fault current limiter and transformer, have been increased gradually. Although the researches and developments are performed for superconducting technologies, many problems such as AC loss and quench phenomenon still remain to design the superconducting transformer. In addition, pre-study on the HTS transformer is a sort of time and expense consuming work, thus it is very worthy of being analyzing the characteristics of HTS transformer in advance through proper simulation programs and skills. With those interests, this paper proposes a simulation model of high temperature superconducting transformer using PSCAD/EMTDC, which can be applied to the utility network simulation readily under various system conditions. It is very important to analyze the high temperature superconducting devices by the simulation for seeking suitable and reasonable parameters for the practical application of those apparatuses in advance. An effective simulation of the high temperature superconducting transformer using PSCAD/EMTDC is performed in this paper and the effectiveness of the proposed simulation scheme is demonstrated through numerical analysis of the simulation results.
