Adjustment of power system stabilizing channels structure of generator’s automatic excitation regulators

Richness of modern power systems with high- performance rapid devices of automatic control, in particular, excitation controllers with power system stabilizers, and also more and more wide use of self-acting counter-emergency control operating on the vapor turbines has provided an opportunity of the complete use of transmission lines´ capacity on conditions of aperiodic and a transient stability and intensive suppression of electromechanical oscillations. For the actual purposes of power stations operation in an electric power system it is necessary to perform multivariate computations for a justification and sampling of stabilization channels tuning of excitation controllers. The methods of choosing of the optimal adjustment of power system stabilizers of generators´ automatic voltage regulators is given in this paper.
