Modern power systems are large sized and rapidly growing. They require constant attention to monitor their performance. Attention is also required to ensure that the voltage stability margin of the power system is above a desired level. In order to achieve the objective, this study proposes a knowledge-based system. It computes using simple Fast De-Coupled Load Flow (FDLF), the state of a power system. Thereafter, the power system is subjected to an additional load at a certain power factor. If the power system collapses, then additional capacitor that needs to be switched on is computed by an iterative procedure. This is done for different load levels and tabulated. Thereafter, in the actual usage, based upon the computed Table, given any load one may determine the level of compensation required to avert voltage collapse.
