Abstract

Za izvedbo analize dinamičnih sistemov potrebujemo njihove matematične modele, ki jih določimo s teoretično ali eksperimentalno analizo sistema. Določitev nelinearnega matematičnega modela sinhronskega generatorja je zahtevna, predvsem zaradi neznanih parametrov, ki so potrebni pri teoretični analizi procesa. V delih, kjer avtorji obravnavajo stabilizacijo sinhronskega generatorja, velikokrat uporabijo poenostavljen matematični modela sinhronskega generatorja. Ta matematični model dovolj dobro opisuje dinamiko sinhronskega generatorja. V diplomskem delu je prikazana določitev zveznih prenosnih funkcij, njihova analiza in simulacija poenostavljenega matematičnega modela sinhronskega generatorja. Bolj podrobno je predstavljena rekurzivna metoda najmanjših kvadratov za določitev diskretne prenosne funkcije. Prav tako so prikazani vsi pomembni simulacijski izračuni, s katerimi smo preverjali natančnost identificiranega matematičnega modela.

Secondary title:	APPLICATION OF IDENTIFICATION FOR SYNCHRONOUS GENERATOR MODEL DETERMINATION
Secondary abstract:	For the conduction of the analysis of dynamic systems we need their mathematical models, which are determined by theoretical or experimental analysis of the system. Determination of the nonlinear mathematical model of synchronous generator is complicated, mainly because of unknown parameters, which are necessary for the theoretical analysis of the process. Within the parts, where different authors are dealing with the stabilization of synchronous generator, they often use a simplified mathematical model of synchronous generator. This mathematical model good enough describes the dynamics of synchronous generator. The diploma is based on determination of a transfer functions, their analysis and simulation of the simplified mathematical model of synchronous generator. There is also more specifically presented the recursive least squares method to determine the discrete transfer function. At the end there is also a presentation of all relevant simulation calculations by which we verified the accuracy of the identified mathematical model.
