Abstract:

This paper proposes a parallel-LC-resonance type fault current limiter (FCL) that uses a resistor in series with a capacitor. The proposed Fault current limiter is capable of limiting the fault current magnitude near to the pre-fault magnitude of distribution feeder current by placing the mentioned resistor in the structure of the FCL. In this way, the voltage of the point of common coupling does not experience considerable sag during the fault. In addition, the proposed FCL did not use a superconducting inductor which has high construction cost. Analytical analysis for this structure is presented in detail, and simulation results using power system computer-aided design/electromagnetic transients, including dc software are obtained to validate the effectiveness of this structure. Also, an experimental setup is provided to show the accuracy of the analytic analyses and simulation results.
