Show moreThe rst part of this research work focuses on modeling and implementation of di erent types of excitation systems for computer simulation of power system transient stability. Excitation system modeling is an important part for the comprehensive modeling of generation systems. Generally, the function of an exciter is to provide direct current and voltage to the synchronous generator eld winding, which will help synchronous machine to build up the satisfactory terminal voltages during steady state operation. In addition, the exciter will provide control and protective function for synchronous machine regarding terminal voltage during dynamic situation when a disturbance happens. The second part of this research work focuses on modeling of loads. Load modeling is a very important aspect for studying power system stability. This research work provides a detailed modeling of three types of static load | constant impedance, constant power and constant current load. Also, this work provides a detailed modeling of the induction motor load model for electromechanical transient simulations. These load models will be helpful for studying voltage collapse issues in real power systems. M.S. in Electrical Engineering, December 2014 Show less
