Optimization of Energy Flow During WWTP Operation - Smart Area Net
Pěcha, Jiří ; Máša, Vítězslav (referee) ; Braciník,, Peter (referee) ; Mastný, Petr (advisor)
The dissertation work deals with the issue of water treatment and possibilities of energy savings during the operation of sewage treatment plants. The aim of the work is to find the potential of alternative energy use, economical consumption, improvement of the facility system management and quality improvement of the wastewater treatment process. In the first part of the work, operating processes, energy flows and energy savings are discussed. To analyze the problematics, larger sewage treatment plants were chosen. Thanks to their size, it was easier to find critical points and test the usage of renewable sources in operation. After the energy audit, the individual processes were assessed and real operation pitfalls were determined. Further steps led to focusing on smaller facilities up to 2 000 PE. This step was carried out with the intention of preparing these plants for the planned legislative change and helping to create or modernize more energy-efficient solutions. Thanks to the establishment of consortium of Brno University of Technology, the Department of Electric Power Engineering and a company dealing with water treatment and automation control, a solution was created that modernize the electrical, automation and water treatment part of the plant operation. This innovative application was installed in the sewage treatment plant, where the issues were debugged, control algorithms were tested and the entire operation was launched in automatic mode. At the end of the wastewater treatment plant modernization, PV panels were installed on the roof, thus partially suppling the object with renewable energy.

Operating diagnostics of PVP
Prášil, Kryštof ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the issue of photovoltaic power plants, especially their operational diagnostics and how to perform this diagnostics. The introduction of the work explains the principle of function of PV cells and describes the procedure for manufacturing these cells. Furthermore, there are mentioned methods of manufacturing individual components for assembling a PV panel. The next part lists the individual components of the PV power plant and describes their function in the entire system. At the same time, the connection methods of the PV plant are described. In the third part, we look at possible defects that affect the performance of PV systems and reduce their economic profitability. We will explain the defects of both the entire PV power plant and the individual panels and components. The following chapter is focused on explanation of individual variables related to PV power plants and what these variables are about. The fifth chapter deals with the content of the standard ČSN EN 62446. The last chapter concerns the diagnostics of the PV system itself, practical tests and evaluation of the results of these tests.
LOCA Energy Performance Study for Simulation of Heavy Accident at NPP
Zemčíková, Kristína ; Andrle,, Karel (referee) ; Mastný, Petr (advisor)
This bachelor’s thesis studies the energy performance of the LOCA device used for the simulation of accidents at nuclear power plants, which can be found at the CV Řež research centre. LOCA stands for Loss of Coolant Accident, which is kind of serious accident that may occur at NPPs. During the accident, the coolant is assumed to be leaking due to a fissure in one of the main pipes. The unique LOCA device at the research centre simulates this accident and is used for testing important components utilised at nuclear power plants. This thesis describes the LOCA device and attempts to determine its energy consumption over the course of a 10-day experiment. By leveraging the consumption curve of the research centre, possible operational optimisations applicable to this LOCA device technology will be proposed.
