| Abstract | ||||
| In this paper, a new hybrid fault current limiter is proposed for primary distribution systems. It incorporates a high temperature superconducting element in parallel with other two branches. The first is an inductive impedance to share the fault current with. The second branch is a gate-turn off thyristor switch controlled to operate the device in either of two modes: the main mode and the stand-by mode. For the main mode, it controls the temperature of the superconducting element and protects it against damaging excessive heating. Instead, in the stand-by mode, it keeps the device applicable without that superconducting element. The design, control and operation of the device is addressed. Its performance in 11 kV distribution systems with DG is investigated. The effect of fault location and fault incidence angle on the device behavior are explored. | ||||
