Damping of the power system electromechanical oscillations with magnitude-phase excitation controller (MPH-EC), which is responsive to the deviations of the magnitude and phase of the terminal voltage phasor, and taking into account the finite speed of propagation the electromechanical waves, caused perturbation the power balance are considered in this paper. The structure of an integrated excitation control system of synchronous machines (IECS SM) using a remote phasor measurement units (PMU’s) to identify the cross-sections (tie lines) of electromechanical oscillations and putting into operation the function of power system stabilizer, installed on the revealed cross-sections of electromechanical oscillations has been proposed. A significant advantage of the proposed method and technology of damping the low-frequency electromechanical oscillations in the power system is its selectivity in relation to the main modes, with the lowest damping ratio, making the greatest contribution to the development of the power system instability, due to the action of the optimal number of MPH-EC located taking into account the given grid topology.
