Abstract :
In this paper a new structure for fault current limiter is proposed. In proposed structure the superconductor coil is replaced by a copper coil and the losses of copper coil and power electronic devices are compensated by an auxiliary circuit. The results show that the proposed structure has less undesired effect on normal operation of system compared with ordinary superconductor type. The main advantageous of proposed structure are no need to superconductor technology and its control-less operation. The analytical analysis and designing characteristics for DC reactor are presented. Also, the simulation and experimental results are presented to show the effectiveness of proposed structure in fault current limitation.
