Proposal for the Procedure of Supply Restoring for Power Plant Teplárny Brno Auxiliary System after Extensive System Fault in PS
Jára, Jaroslav ; Vaculík, Petr (referee) ; Orságová, Jaroslava (advisor)
This work deals with the issue of supply restoring for heating plant Teplárny Brno, a. s. Špitálka division, after a system-wide failure of the “blackout”. The thesis solves the “black start” of the Špitálka Teplárny Brno operation by delivering a voltage from the hydroelectric power Vír I, proposes a methodology for commissioning of individual devices, up to phasing the generators with subsequent possibility of creating an “island mode” in the area of Brno city, which the work already does not deal with. The work also deals with the preparation of the operational test, while starts of the selected devices are tested. The schedule of commissioning of each device is supported by calculations of the parameters for the entire system with regard to voltage drops while connecting the high load. The result of this work is the proposal of methodological process of supply restoring for power plant Teplárny Brno – Špitálka division, by submission a voltage from the hydroelectric power Vír I, which can be used both in any system-wide failure of the “blackout”, or during the operational test.

Degradační procesy u strojů pro zpracování půdy
Kubík, Petr
The diploma thesis is focused on degradation processes in machines tillage. The main intention of this thesis is monitoring and comparing abrasive wear of current technical materials. Wear is evaluated by using weight decrease at operational and laboratory test. In the theoretical part is processed basic division machinery for tillage, description of the particular degradation processes focused on abrasive wear of agricultural machinery. The practical part is focused on describing particular technical materials. It describes the production of test specimens and their heat treatment. Followed by operational and laboratory tests. The obtained results can recommend suitable material that can withstand the best abrasive wear and ensure functional as optimally sharp cutting edge.
