Abstract [en]

This paper provides understanding in how different synchronous machine models influence locations of its eigenvalues in the complex plane. Four different synchronous machine models are presented. By simulating and linearizing them in a small network the paper shows how each expansion of them influence the number of eigenvalues and their locations. It is shown how the damping constant D for low-order models can be set to obtain the same damping as for high-order models. The paper also shows how the eigenvalues of the synchronous machine are affected when the output signal from a turbine model is defined as either mechanical power or mechanical torque.
