This paper proposes a new parallel-LC-reson
ance-type fault current limiter (FCL) that uses a resistor in
series with a capacitor and therefore, it can simulate load
impedance during fault. By this way, The proposed FCL is
capable of limiting the fault current magnitude near to the
prefault magnitude of distribution feeder current by placing
the resistor in the structure of the FCL. The voltage of the
point of common coupling does not experience considerable
sag during the fault In comparison with the previously this
FCL does not use asuper conducting inductor in the resonant
circuit, due to high cost the overall operation of the
mentioned FCL in normal and fault conditions has been
studied in detail. Also, the simulation and experimental
results have found.

Fault Current Limiter (FCL)
In this paper, a new topology of parallel-LC-resonancetype
FCL that includes a series resistor with the capacitor
of the LC circuit has been introduced. The analytical
analysis and design considerations for this structure have
been presented. The overall operation of the mentioned
FCL in normal and fault conditions has been studied in
detail. Also, the simulation and experimental results have
been involved to validate the analytic analyses. All
previously proposed FCLs have good Fig. 19. PCC voltage

ms). Fig. 20. Capacitor voltage during fault (voltage/div.:
50 V; time/div.: 25 ms). current-limiting characteristics.
However, as shown in this paper, the proposed structure
can improve the power quality of the distribution system
in addition to fault current limiting. The proposed
resonance-type FCL can limit the fault current in a way
that the PCC voltage does not face considerable sag during
fault. This means that, in case of transient faults, it is not
necessary to open the line by a circuit breaker. By using
Rsh in the proposed topology, the transient state after fault
damps quickly. In addition, it is capable of controlling the
fault current at constant value that is not possible in
common seriesresonance-type FCLs.
