Calculation and verification of current limiting properties for Saturated Iron Core Superconductive Fault Current Limiter

Abstract

This paper introduces a simulation model of Saturated Iron Core Superconducting Fault Current Limiter (SICSFCL) using SIMPOWER of MATLAB and establishes an actual model for the 35kV/90MVA SICSFCL installed in Puji substation at Kunming. The model is used to simulate the artificially imposed three-phase short-circuit and the results are compared to the live grid test results, which were carried out in July 2009. The SICSFCL simulation model is verified effectively.
