The electric industry has undergone a considerable change in the past decade throughout the world. The feature change is to promote competition among utilities and to form active power market with reliable and less expensive electricity. Under these circumstances, stabilization and voltage stability problems of power system are very important. The power systems engineer is investigating the effect of the capacity of the braking resistor and the timing of insertion for the improvement of the stability level. In this paper, experiments are carried out the optimal size and switching of braking resistor and shunt capacitor etc. The studied system model for experiments consists of a single synchronous generator connected through two parallel transmission lines to an infinite bus.
