A global power system transient stabilizer and voltage regulator is proposed in this paper. Two independent controllers i.e. transient controller and voltage regulator are designed. In order to design voltage regulator we use simple neuro controller and for transient stabilizer we use Neural PSS. The final control action is the sum Neural PSS and neuro-voltage regulator. To achieve the global control action that guarantees both transient stability and voltage regulation, we used a membership function that was a function of measurable parameters of the system. The proposed global control law acts in a manner in which in the transient period, the transient stabilizer is the
dominant controller and in the post transient period, the voltage controller is the dominant one. The effectiveness of the proposed global control action is demonstrated through some computer simulations on a Single- Machine Infinite-Bus (SMIB) power system.
