Autonomic fault recorder designed for a distribution transformer station MV/LV
Gaborčík, Michal ; Drápela, Jiří (referee) ; Topolánek, David (advisor)
This master’s thesis deals with realization of fault recorder designed for a distribution transformer station. In theoretical part is created research about operation of distribution transformer stations and about analytic methods, which gives bases for fault detection in power network. The practical part consists of design and realization of fault recorder in LabVIEW interface using CompactDAQ measurement platform. Purpose of this recorder is monitoring and recording of voltage and current waveforms on secondary side of transformer station during the fault in high voltage network. Principle of fault detection is primarily based on level monitoring of voltage negative symmetrical component. Fault recorder has been successively optimized and the final version is presented in this thesis. At the end functionality of designed system is evaluated on simulated fault in a model of high voltage network.

Design of domestic energy supply system using renewable energy sources
Gaborčík, Michal ; Pavelka, Tomáš (referee) ; Matoušek, Antonín (advisor)
This bachelor thesis deals with possibilities of utilization of renewable energy sources for domestic power supply. In theoretical part is created research about available technologies using solar collectors, photovoltaic systems and heat pumps. In practical part there are calculated expected values of energy needed for heating of family house, domestic hot water heating and electrical consumption of appliances. These values are bases for system design using air to water heat pump for heating and domestic hot water heating. As far as photovoltaic system is concerned there is comparative design of systems using polycrystalline and thin-layer technology. At the end both designed systems are evaluated from technical and economical points of view.

Preventive maintenance of power equipment based on actual technical condition
Gabrys, Dominik ; Gaborčík, Michal (referee) ; Radil, Lukáš (advisor)
This bachelor thesis is focused on issue preventive maintance, diagnostics of high voltage cables and optimization for power distribution equipment. Thesis is divided in two parts, teoretical and practical. Teoretical part contains survey about reliability centered maintance, options of maintance and overview of czech distribution systems. Practical part contains diagnostics of high voltace cables and analysis data for create more efficient maintance.
