Abstract:
1. A method of initializing a deduction, from estimated model parameters (a 1 , a 2 , . . . ) of a parametric model of an electric power system, of frequency and damping (f, ξ) of an electromechanical oscillation mode of the power system, wherein the estimation of the model parameters (aj, a 2 . . . ) is based on a series of measured values (y 2 1 , y 2 2 , . . . ) of a second system quantity (y 2 ) of the power system and wherein said model parameters (a 1 , a 2 , . . . ) are adaptively estimated every time a new value (y 2 k ) of the second system quantity (y 2 ) is measured, the method comprising: tuning, in a processor of a digital computer, a set of tuning parameters (tp tuning, in the processor, the set of tuning parameters (tp determining, in the processor, a conditioning gain (G
