Auxiliary winding supplying the voltage regulator of synchronous generator
Hrtáň, Michal ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
The theme of this thesis is the design and verification of the auxiliary winding to supply the voltage regulator of the synchronous generator. The synchronous generator for which the auxiliary winding proposed is three-phase, low voltage with double layer random wound stator winding. The generator excitation is brushless with auxiliary rotating exciter. The auxiliary winding is designed for placement in the stator teeth, along with the main winding. The sizing of the auxiliary winding is derived from the power requirements the voltage regulator. Draft winding is validated analytical calculation and finite element method (FEM). The auxiliary winding has been implemented in the production of the generator. The Features of the auxiliary winding have been verified by measuring the by electrical testing room and the test results are evaluated.

Determination Parameters of Synchronous Machines according to Measurement
Hrtáň, Michal ; Vaněk, Jaromír (referee) ; Hájek, Vítězslav (advisor)
This "Determination Parameters of Synchronous Machines according to Measurement" bachelor thesis describes methods of tests necessary to determine loss and efficiency of electrical machines with focus on synchronnous ones. It determines calculation procedures for evaluating the measurements. Furthermore, it deals with measuring mechanical vibrations and noise of an electrical machines. Definitions of given tests are written up with regards to contemporary norms. From above mentioned information comes a serviceable tool for automatic measurement protocol generation, which is an electronic form. The measured values are the input of the form. The output of the form is the measurement protocol with results of calculation and graphs of characteristics. For the thesis purposes, the form was filled in with acquired values from tests of a specific synchronnous machine. The related calculations for determining the machine parameters are stated.
