Abstracts: Voltage stability is given very high importance in the power system studies, In the present studies, the voltage stability is determined by a method of on line monitoring of power system based using measurements like voltages, active power and reactive power etc. This is proposed with the aim of detection of the voltage instability. Since in the transient process, at any time point, the electrical power of the system is in balance, and Kirchoff -laws is obeyed, this indicator still works during transient process. From the indicator, it is proposed to predict the voltage instability or the proximity of collapse. An IEEE 6-bus system is taken as a study case to test the efficacy of the proposed systems. Reactive Power Control and Voltage Stability is major concern in to days power system. By Providing Some kind Of compensation At load side or in system voltage stability Can be increased and Racitve power can be controlled.
