Abstract :
This paper presents an application of the singular perturbation method to power system simulations. The focus is on treatment of the fast states associated with generators and their controls. Models of generators, static exciters, power system stabilizers (PSS) and governors are reformulated using singular perturbation techniques. These singularly perturbed models are implemented in a two-area, four-machine power system. The results bear a close correlation to those obtained from a full model in which the fast states are fully simulated. This study contributes a new and efficient method in dealing with the fast states to speed up power system simulations
