| Abstract: | In order to meet the requirements of protection,this paper proposes a new DC superconducting fault current limiter (SCDCFCL) and introduces the principle of SCDCFCL. The mathematic model is established,and the MATLAB simulations of two different DC sources are carried out. The simulation results confirm that the new SCDCFCL has no influence on power system in normal state.However, when the fault happens,it can limit the fault current perfectly. |
