Steady State Accuracy of Second-Order Generator Dynamic Models in Generator Parameter Validation Testing

This article analyzes and compares existing second-order generator dynamic models including two new models under development. Model structures and saturation methods are reviewed for existing popular second-order generator models. Analyses on the steady state accuracy of the dynamic models and their applications in generator model parameter validation testing using stator current interruption method are discussed. Theoretical background of the new GENQEC model is provided and the advantage of the GENQEC in parameter validation is proven through mathematically derived equations from the structure of all the models analyzed.
