Impact of fault resistance and fault distance on fault current reduction ratio of hybrid SFCL

Abstract

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.
