Determining dominant oscillation modes of generator excitation controllers in power systems

摘要

A method for determining dominant eigenvalues of a linearized mathematical model of a multimachine power system is proposed. The method enables the generator with the least oscillatory stability margin to be identified and the natural frequencies of the generators to be determined. The method was used to develop an algorithm for determining the tuning parameters of excitation controllers for the generators in complex power systems. Results of comparative calculations (ire presented, which confirm the efficiency of the approaches proposed.
