Transient Analysis of Indirectly Grounded Power System

Abstract:

At present the transient mechanism in lumped parameter for analyzing single-phase grounding fault in indirectly grounded power system exist deviations. This paper analyzes the amplitude-frequency and phase frequency characteristics of the impedance in line-mode network and zero-mode network through the distribution parameter model of transmission lines. This paper also analyzes the mechanism of LC resonant process. A high precision model of single-phase grounding fault in system with neutral point ungrounded is established using simulation software like ATP and Matlab, and the resonance mechanism of the single-phase grounding fault transient process in the proposed system with neutral indirectly grounding system simulated and identified.
