Overbye, Thomas J. Westendorf, Alexander M. 2012-02-06T20:10:09Z 2012-02-06T20:10:09Z 2012-02-06T20:10:09Z 2011-12 Power system transient stability studies are complex and can take a substantial amount of time to simulate. The Multirate integration method is one way to speed up simulation studies. This thesis studies the effects of using a type of Multirate simulation method in a software package. In this study, the Multirate method is used mainly on simulating fast transients resulting from excitation models. Proper subinterval values to maintain stability in PowerWorld Simulator are established for exciter eigenvalue ranges. Subintervals are applied to exciter models of a 16,386 bus system based on exciter eigenvalues. Application of the Multirate method on exciters provides a time savings for each time step, with the largest being a 10 percent faster solution when using a one cycle per second time step.
