Abstract

The paper presents a study of single-phase auto-reclosing of the Vietnam 500 kV transmission system. The success of the single-phase auto-reclosing depends on the extinction of the secondary arc. Therefore, the influence of several factors such as shunt and neutral reactors, faulted phase and location, capacitive and inductive couplings and series capacitor discharge on the extinction of the secondary arc is investigated. The paper presents the influence of single-phase auto-reclosing on the transient stability of the Vietnamese power system. Finally, methods to increase the success of the single-phase auto-reclosing scheme also are investigated
