Optimal implementation of SFCL for Voltage sag Mitigation in Power Distribution System

摘要

For the improvement of voltage sags immunity of the whole distribution network, this paper proposes a method to better apply the position of superconducting fault current limiter (SFCL). The mathematic model of SFCL and its risk of installing in various locations on voltage sags is firstly put forward. An identical method for vulnerable areas and lines is utilized to plan for the location of SFCL. Verification and conclusion are given as follow to present the effectiveness of the recommended strategy.
