Performance Analysis of Transient Current Limiters in a Distribution System

Abstract

This paper deals with the performance evaluation of a three-phase transient current limiter in distribution systems. A simulation model based on mathematical model of a three-phase, transient current limiter has been developed. The problem is formulated to justify the stable and harmonic free twelve-pulse and six-pulse converter based transient current limiter. Firstly, conventional methods like Bode Plot, Nyquist Plot and Nichols Chart are used to investigate the stability of twelve-pulse and six-pulse converter based transient current limiter. Next, a comparative analysis using fast Fourier transform is used to check the system harmonics using MATLAB simulation. The proposed design is found to be more efficient in making the system stable and harmonic free.
