Stability and harmonic analysis of a transient current limiter in distribution system.

This paper proposes a methodology to investigate the stability of transient current limiter (TCL) in distribution systems. The problem is formulated to justify the performance of 12-pulse and six-pulse converter and make an unstable system to stable condition. The proposed approach explicitly deals with stability as well as minimization of total harmonic distortion. Firstly, the conventional methods of Nichols Chart, Nyquist Plot and Bode Plot used to investigate the stability of the network using TCL. In the next stage, a modified TCL circuit is inserted in the network system to make the system completely stable. A comparative analysis using Fast Fourier Transform (FFT) is shown to make the system harmonic free using MATLAB simulation. The proposed design is found to be more efficient in making the system stable and harmonic free. [ABSTRACT FROM AUTHOR]
