Abstract
Identification of power system modal oscillation damping in frequency has become more feasible through angle measurements and communication systems. Frequency domain estimation provides reasonable estimates of these parameters if given very long estimates and the modes are well separated. This paper shows how the estimation is improved if the modes are decoupled as part of the estimation process. The results show good performance compared to a key previous method.
