Σκοπός της παρούσας διπλωματικής εργασίας είναι η ανάλυση της λειτουργίας τριφασικής σύγχρονης γεννήτριας εκτύπων πόλων κατά την εκκίνηση, καθώς και την ηλεκτρομαγνητική μελέτη ενός συστήματος δύο βαθμών ελευθερίας (στρόβιλος-γεννήτρια). Τέλος, θα γίνει σχολιασμός των αποτελεσμάτων. / The aim of the thesis is to
study and analyze the operation of three phase synchronous generators with salient poles at
startup, and electromechanical advancement of a system of two degrees of freedom (turbinegenerator)
which is oscillated. Comments of the findings will follow in the last chapter.
The thesis is structured in five chapters. Chapter 1 introduces the literature review where there
is a general description of the basics of electric energy and the principles regarding the
construction and operation of synchronous machines and in particular three-phase synchronous
machines with salient poles.
In chapter 2, a comprehensive analysis of oscillating systems is made of one and two degrees of
freedom. A comparison is then made between linear and rotary motion. In the end the
mathematical model of a rotating part with two degrees of freedom and the constant of twisted
spring is presented.
Chapter 3 shows the main steps followed during the design stage of the model and it includes
images of the main parts of the generator and the control windows of the software Opera-2d.
In Chapter 4 we make a reference to the PI-controller which was used to control the speed of
the generator. Then we give the parameters of analysis.
In Chapter 5 shows the presentation of the simulation results during the startup of the
synchronous generator until the steady state.
