초전도 한류기를 적용한 계통의 3상 단락사고에 대한 EMTDC 시뮬레이션

We have performed an EMTDC simulation for the current limiting effects of a superconducting fault current limiter (SFCL). A three-phase fault in the 154 kV transmission line between the gaepo and Sungnam substations produced a fault current of up to 60kA. The SFCL with 100 Ω impedance after quench limited the current to 17kA within a half cycle. This limited current is well below the upper limit of a circuit breaker, suggesting the impedance of the SFCL in the transmission line is sufficient.

Applying HTS to microstrip patch antenna, one of the most difficult problems is the impedance matching at feed point. For good impedance matching, exact solutions of input impedance must be calculated. In this paper the solutions of it were presented. To do this, using Moment method based on Ground dielectric slab Green function, we calculate the current distribution and the real part and imaginary part of input impedance.
