The developed modal method for analyzing oscillating static stability of power systems is based on eigenvalues and eigenvectors. As a mathematical model to the study we use a system of linearized differential equations that describe the behaviour of synchronous machines and their excitation systems during minor disturbances. This approach allows us to analyse the static stability of large power systems, evaluate stability margins, degree of damping modes, and set adjustment mechanism for mode parameters to improve mode stability. We investigated the impact of generator excitation system replacement on stability of Ukraine’s power system. The suggested modal analysis is implemented in the DAKAR software suite [1].
