Mobile photovoltaic power plant
Klíč, Tomáš ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis is divided into two parts, namely the theoretical and practical part. In the theoretical part, the issue is dismantled from the current state of electric power, share the production of individual sources, the market for photovoltaic and mobile photovoltaic systems through the description of the theory of solar radiation and all the necessary components to build the isolated photovoltaic power plant. The practical part deals with dimensioning, selection of suitable components and the actual one own design and implementation of a mobile photovoltaic power plant.

Probabilistic approach for evaluation of the safety of earthing systems
Klíč, Tomáš ; Vyčítal, Václav (referee) ; Topolánek, David (advisor)
This thesis deals with the grounding systems, namely their evaluation in terms of safety. The introduction describes the grounding theory, the principle reason for their use, and the difference between the current evaluation method of grounding systems in terms of security against electric shock and a new approach. Another part is devoted to describing the assessment of grounding systems in terms of safety, respectively. permissible touch and step voltages using currently based ČSN and PNE. Another essential part of the theoretical description of how to assess safety of grounding systems in terms of probabilities, consisting in determining the probability of death of a person, including the probability of failure and the probability of a man close to the rated grounding system during the disturbances, and classify the probability tolerable, moderately tolerable or intolerable and if necessary, assign the risk group appropriate solutions to mitigate the risks. The work, of course, the practical part. Designed for probabilistic approach will be processed illustrative example of evaluation chosen grounding system, which would be the basis for the negotiation of an international group CIRED / CIGRE focused on this issue.
