Abstract: Today power systems play an important role in supplying energy to meet rise in load demand. But this increase in energy is not sufficient to meet the increase in power demand. Alternatively if we installed new power plants than we have to installed new transmission lines in which the cost rises. Due to increase in the power demand continuously and with the deregulation of electricity in the market it is necessary to load the lines up to its maximum thermal limit known as steady state stability limit. It is the maximum flow of power without losing synchronism. This thermal stability limit is limited by transient stability limit. Hence to improve transient stability limit we use facts devices and here series facts device thyristor switched series capacitor is used. It is a discrete control device and the proposed controller is designed. In this paper transient stability of IEEE 9 bus, 3 machine system is designed under severe disturbance under MATLAB Simulink.
