Voltage stability problems are becoming increasingly evident since large amount of power are being transferred from long distance and bulk power systems operate close to their stability limits. Accurate recognition of voltage collapse point and contingency analysis of load voltage stability make it possible for procedures to prevent voltage collapse during contingency. In this paper, IEEE 14 Bus system is taken and load flow is conducted using Power System Analysis Toolbox (PSAT).A static capacitor is connected to bus to make the voltage never drop one p.u. It will control the voltage when a transmission line is removed, like a emergency contingency, and generate the reactive power. Even a load is increased; still the static capacitor will control the voltage.
