Title: Voltage Instability and Voltage Collapse as Influenced by Cold Inrush Current
Authors: Y. A. Mobarak, and M. M. Hussien
Abstract: The occurrence of voltage instabilities or voltage collapses depend on the duration of the persistence of the fault and on the type of fault, some faults lead to voltage instabilities, others lead to voltage collapse. Evaluation of fault durations causing occurrence of voltage instabilities or collapse is the main goal of this paper. This paper searches for the effect of peak inrush current and its duration periods initiation of voltage instability, with lagging and leading load power factors at certain loads buses. Also, this paper searches about the fault duration required for voltage collapse. The influence of the cold inrush current on this fault duration is studied. .Form several tedious trials, it is noticed that, the phenomena of voltage collapse can be occurred with some line opening in the studied system.
Keywords: Voltage Instability – Voltage Collapse – Cold Inrush Current – Power System Stability.
