Development and Implementation of Energy Savings and Energy Management Methodology in an Industrial Enterprise
Dudarev, Ivan ; Demeč, Peter (referee) ; Suchánek, Rostislav (referee) ; Blecha, Petr (advisor)
V současné době se problematika energetických úspor dostává do popředí zájmu jak na úrovni jednotlivých podniků, tak i na úrovni celého státu. Často bývá příčinou sporů ve vědeckých kruzích i mezi odborníky z praxe. Lidstvo tradičně začalo využívat energii z minerálních přírodních zdrojů, které však ve srovnání s obnovitelnými zdroji energie mají omezení. Výzkum a implementace moderních technologií jsou ztíženy otázkou investic a časově omezeny. Proto se evropská strategie energetické bezpečnosti zaměřuje na energetickou účinnost, která je jedním z nejefektivnějších způsobů zlepšení bezpečnosti spotřeby energie. Velké společnosti a podniky jsou jedním z hlavních spotřebitelů energie. Proto je tato vědecká práce zaměřena na problematiku úspor energie a zlepšování energetické účinnosti podniku. Těžiště práce spočívá ve vytvoření a zavedení metodiky pro úsporu energie a managementu hospodaření s energií ve výrobním procesu automobilového podniku. Dále je pro účely této práce vytvořen a popsán způsob vizualizace spotřeby energie v prostředí virtuální reality

Application of Ultracapacitors in Traffic Systems
Kalina, Emil ; Vorel, Pavel (advisor)
The work deals with relatively new components allowing electric energy accumulation – ultracapacitors. It focuses on their application in traffic systems – in independent electric vehicles. Design and verification of a system with ultracapacitor and DC/DC adaptive converter was done. Control of the adaptive converter modifies very positively the time wafeform of the traction accumulator current during the drive cycle. The designed connection of ultracapacitor and DC/DC converter implemented in the drive structure of experimental electric vehicle with induction machine contributes to increment the action radius of the vehicle by 16% (determined by experimental verification). This result was achived particularly by limitation of traction accumulator current peaks, And by more effective storage of energy gained by recuperative braking of the vehicle as well. The core of the system is a control of the adaptive converter in order to provide an active filtration of the accumulator’s current to its long-period mean value, i.e. elimination of current (power) peaks. These are caused by acceleration from non-zero initial vehicle speed or by recuperative braking. This is done by a subsidiary current loop. The converter has a superior voltage regulation loop, which sets in long-time period the voltage of ultracapacitors to the proper value – indirectly dependent on the speed of the vehicle. This ensures the appropriate energy management of the ultracapacitor. In the following, properties of test set of ultracapacitors were verified. Finally, methods of suppression of capacity variability influence in series connection of these components were compiled and critically reviewed.

Evalution of Economic Efficiency of EPC Projects
Vlčová, Zuzana ; Šourek, Bořivoj (referee) ; Korytárová, Jana (advisor)
The issue of energy saving building is a current topic of today. The increasing costs of operating buildings reduce economic efficiency of the organization operations. A large part of the operating cost is energy cost. An effective tool for improving the energy performance of buildings is an EPC method. The implementation of energy projects through EPC is offered by Energy Services Company. This thesis evaluates the economic efficiency of the project implemented by the EPC and analyses its risk factors. The subject of EPC project is modernisation of an energy sector of a hospital building. The economic efficiency of the project is interpreted on the basis of economic indicators Net Present Value, Internal Rate of Return and Profitability Index. There was also performed Monte Carlo simulation supported by Oracle Crystal Ball software within the analysis of risk factors for the project.

The effective use of information system MES (Manufacturing Execution System) in the food company is the main topic of this master's thesis. The modularly built system provides valuable support of the production process on operational level. The thesis concentrates on the analysis of already implemented standard solution in the company's factory. Main goal is to propose expansion of the functioning area to the already existing solution, aiming for effective use of energy resources. It was necessary, in order to be able to achieve the goal, to get familiar with the complex corporate IT/ICT construction in alignment with the company's energy concept. The proposed solution is leaning on application of internal MES project methodology, leading to exact specification of energy component in the factory production frame. The thesis conclusions, besides the proposed solution itself should serve as an argument about the efficiency of starting MES system in other production factories of the company.
