Abstract

Superconducting fault current limiters (SC-FCL) are expected to be introduced in electric power systems to suppress a short-circuit fault current. In present paper, three line-to-ground fault and single line-to-ground fault are assumed to happen at the exit of bus in a 275kV electric power system . The SC-FCL is supposed to be a commutation type, which consists of a non-inductive superconducting coil and a current limiting element (resistor or reactor). The introduction merits of the SC-FCL were investigated quantitatively by EMTP (Electro-Magnetic Transients Program) from the viewpoint of the current limiting performance, the prevention of the voltage drop at a load bus, reduction of the overvoltage and the joule heat generated in the SC-FCL. Through the performance evaluation of the SC-FCL in the power system, desired specification of design and operation parameters of the SC-FCL were given qualitatively. The differences of introduction merits due to the FCL-types and introduction location were also pointed out.
