Abstract :
The solutions for the harmonic reduction of the superconducting fault current limiter system was discussed in this paper. The ideal high-Tc SFCL system with the DC reactor has negligible influence on the power system under normal operations. However the high-order harmonic currents are generated from the 6-pulse bridge configuration. Passive filter techniques employ tuned LC filters at 5th, 7th, 11th and 13th harmonic frequencies. The harmonic currents can be eliminated using the tuned LC filter and the special bridge configuration. Simulation results are given to validate the harmonic isolation feature at harmonic frequencies and also demonstrate the harmonic filtering process to meet IEEE 519 harmonic standards.
