Abstract
U ovom diplomskom radu detaljno se opisuju matematiˇcke modele sinkronog generatora i asinkronog motora sedmog reda. Ovi modeli nuˇzni su za razumjevanje dinamiˇckih vladanja sinkronog i asinkronog stroja. Za sinkroni generator matematiˇcki se model prikazuje u prostoru stanja te linearizira kako bi se moglo odrediti svojstvene vrijednosti generatora u zadanoj radnoj toˇcki, tj. njegove modove. Na temelju modova konkretnog generatora koji napaja vlastitu potroˇsnju HE Jajce 1 i step odziva generatora u praznom hodu te pomo´cu modalne analize parametrira se regulator uzbude i brzine vrtnje. S parametriranim regulatorima simuliraju se dinamiˇcki odzivi sustava. Najizraˇzenije prijelazne pojave nastaju pri zaletu pumpi rashladne vode na sustav u pogonu. Na temelju simulacija donose se zakljuˇcke o naˇcinu zaleta pumpi rashladne vode i utjecaja istih na sustav

A detailed description of seventh grade mathematical models for synchronous generator and induction motor is given in this masters thesis. Understanding these models is necessary for evaluation of dynamic responses of the represented machines. For synchronous generator, mathematical model is derived in linearized state space form. This form is used to calculate the eigenvalues, also called modes of the synchronous machine for given stationary state. Calculated modes of the synchronous machine that drives the auxiliary drives of the hydro power plant Jajce 1, together with step response test and modal analysis are used to choose the parameters for excitation and turbine regulators of the synchronous machine. With completed regulator parameters set, dynamic responses of the power plant auxiliary systems are simulated. The dynamic respones that result from starting the pumps ”pumpa rashladne vode” 1 and 2 are the most emphasized dynamic responses. Simulation of various events regarding the two pumps brings conclusions about the way pumps are supposed to be started and their influence on the entire system
