|Keywords:||Electrical and Electronics;Electrical and Electronics|
|Abstract:||<p>Dynamic stability of multimachine and single machine-infinite bus systems is considered. System models are described, which include detailed generator, turbine, governor and exciter components, in addition to dynamic representation of mechanical loads and electrical networks. The overall modeling concepts are applied to a number of practical applications to demonstrate their behavior in power systems dynamic studies.</p> <p>A variety of linear dynamic equivalents are employed to reduce the complexity of stability studies for multi machine power systems. Undrill's technique for constructing linear dynamic equivalents is extended and improved in this thesis.</p> <p>Various reduction techniques are applied to reduce the order of the system. Mainly they are aggregation and singular perturbations techniques. The interactions between the reduction techniques and dynamic stability are explained.</p> <p>Insights are presented into the interpretation of eigenvalues and eigenvalue sensitivities as they reflect the various aspects of power system stability predictions in high order models, they are extended to be applied in reduced order models.</p> <p>The concepts considered are employed in the analysis of several examples utilizing actual power system data.</p>|
