Summary Superconducting fault current limiters (SFCLs), as the novel power system devices, have attracted attentions in the last years. However, in order to achieve the maximum benefit from SFCLs, their interaction with power system should be comprehensively evaluated before equipping the power system with them. This paper investigates the effect of fault resistance and fault distance on the steady‐state fault current reduction ratio (FCRR) of hybrid SFCL. Based on the equivalent circuit model, analytical studies are presented to obtain the relation between 2 abovementioned factors and the FCRR of hybrid SFCL. Then, through the detailed simulation studies, the current limiting behavior of hybrid SFCL is evaluated when the value of fault resistance and the position of fault change in wide range. As a result, although the hybrid SFCL is able to reduce the fault current under different circumstances; however, FCRR significantly varies under outside the control changing circumstances. For far faults and faults with high fault resistance, the FCRR of hybrid SFCL is not as good as the other fault conditions. Hence, in the last section of the paper, the remedial actions to enhance the performance of hybrid SFCL during these conditions are proposed.

“…In contrast, a fault in conventional distribution systems will not cause a significant voltage drop in the entire distribution system, provided that the fault current is primarily limited by the respective line impedance, that is, the fault is electrically far away from the substation. Since the conventional distributional system does not provide any fault current limitation, a current limiter (in addition to the circuit breaker) must therefore be designed to limit either the peak value of the initial transient fault current and/or its steady-state value [5].…”

This study addresses the timely issues of modelling, and defining selection criteria for, a solid-state fault isolation device (FID) intended for use in power electronics-based distribution systems (PEDS). This work subsequently derives the FID parameters by mapping the characteristics of a conventional medium-voltage distribution system onto that of the PEDS envisioned under a new multiuniversity Engineering Research Centre. When conventional circuit breakers are used in distribution systems, they have a relatively long clearing time, causing the voltage to collapse for a significant time. A semiconductor circuit breaker, however, is expected to be able to switch fast enough to keep a voltage disturbance within acceptable limits. The main focus of this study is to address the operational issues of the interaction between the power electronic converters and the solid-state FID. The utilisation of rate of current decrease (di/dt) control during turn-off in conjunction with passive clamping devices to manage the overvoltage that results from very fast circuit breaker operation is introduced. In contrast to a simple conventional RC-snubber circuit, the proposed overvoltage management avoids high leakage current, which is the undesirable drawback of RC-snubber circuits. The presented prototype is experimentally verified with low and medium-voltage test circuits.
