Performance Analysis of Voltage Sag Compensation Using Super Conducting Fault Current Limiter for R or RL Loads

Abstract

inductor. The proposed FCL 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 paper, the improvement of the voltage sag is analyzed according to the fault location, resistance value of SFCL, and the length of the loop power distribution system. First, a resistor-type SFCL model is used using the MATLAB/SIMULINK. Finally, when the SFCL is installed in the radial or loop power distribution system with various lengths, voltage sags are evaluated according to various fault locations. The results of voltage sag analysis in the loop system are compared with the voltage sags in radial power distribution system. In extension to the work discussed in paper the system can be tested under different Loading conditions and a study on positioning of super conducting fault current limiter can be analyzed.
