Optimization of cooperation power station blocks
Smarž, Patrik ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The introduction of this bachelor´s thesis deals with basic terminology used in the power plants. It details the terms: work, power, and efficiency. The other part deals with basic thermal circulation of a condensation power plant and possibilities to increase the thermal circulation efficiency. It describes improvement of admission steam parameters, especially dealing with a steam superheater. Regeneration heating, steam heating and pressure decrease in the condenser are explained as other options of the thermal circulation efficiency improvement. Furthermore, it deals with consumption and cost characteristics of a power generating facility and optimisation of operation of power plants and heating plants in the EC. The model showes an explanation of an optimal distribution of power outputs of two cooperating power units at a given load.
Use of Cogeneration in Family Houses
Pusztai, Radek ; Mastný, Petr (referee) ; Baxant, Petr (advisor)
In the first part of the thesis is elaborated a general view on the issue of cogeneration - a joint production of heat and electricity. In addition to technical and economic aspects are also mentioned basic modes of operation of cogeneration units. Furthermore, installation conditions in the family house and legislative acts associated with the operation. The next section describes the technical parameters of the unit - TEDOM T7. Subsequently, the work performed calculations of the energy needs of the family house. In the next part there is an economic calculation of the object with reference to other sources of heat.

Project Documentation of Electrical Wiring with Automation in Scope for Realization of Family House
Jaroš, Zdeněk ; Janík, Daniel (referee) ; Mastný, Petr (advisor)
The aim of this work is to get acquainted with problems connected with a designing of power and data distribution, a definition of principles necessary for a drawing design and a project realization of an electrical installation for a detached house. The first part of the thesis deals with the definitions and principles related to safety and security administration, which must be respected at designing the project documentation. In the following part of this thesis there are presented the conditions and selected methods of connecting the object to the low voltage distribution network, methods of conducting heavy and low current rake and the lighting design. The second part deals with the designing of a specific electrical installation project for a detached house. The content presents the heavy and low current installation in a ground plan of the house, a switchboard design, a lightning conductor, and a technical documentation in accordance with actual technical standards. The technical report also includes economical evaluation of the project.
Design of Savonius wind turbine
Sedlačko, Jozef ; Mastný, Petr (referee) ; Morávek, Jan (advisor)
Power engineering ranks among faster growing industries of power production by renewable resources in the last decade. Savonius rotor, as small wind source, was subjected to research and innovation like other wind power sources. This thesis is concerns proposal and realization of Savonius rotor for lab purpose. In the first part, its principle and characteristics are mentioned. Second part concerns mathematical proposal of measurements and geometry. The last part of the thesis consists of measuring and evaluation of basic parameters of this type of rotor.
Photovoltaic systems in the cities
Dobiáš, Pavel ; Procházka, Zdeněk (referee) ; Mastný, Petr (advisor)
This Bachelor thesis' main goal is to introduce a potential reader with the photovoltaic system questions and its utilization in many applications. In the leading chapter the thesis deals with the potential of the energy which is radiated from the Sun towards the Earth. It tries to analyze the common problems of using this energy. The next part deals with simple semiconductor operating principles and explain the principles of photovoltaic cell functions. The upcoming part deals with the construction and basic types of photovoltaic cells and show the possible ways in their development. In the next part there are analyzed many types of photovoltaic systems and their application in praxis. In the next part the reader is introduced with the meaning of photovoltaic as a renewable source and with its support in the European Union and Czech Republic. The last part deals with design of four devices which uses photovoltaic system as a power source and which can be used in the city agglomeration environment.
Mathematical modeling of a wind turbine
Osička, Aleš ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
The aim of this paper is to acquaint the readers with basic classification of wind turbine configuration by used electric generator, with speed and power control used in power plants and with mathematical model of wind and parts of power plant. Procedure of making model in applications Mathematica and MathModelica is described in the other part of this paper. There were made models of power plants with squirrel cage asynchronous generator, one with pitch control, the other with stall control. In the last part of the thesis comparison of model behavior of both models with the same input conditions was made.
Cyclic tests of lithium storage systems
Koňak, Tomáš ; Mastný, Petr (referee) ; Morávek, Jan (advisor)
The bachelor’s thesis focused on problematics of cyclic tests of lithium storage systems. The thesis introduces the methods of accumulation of electricity. The practical part deals with the assembly of a workplace for the implementation of automatic discharging and charging cycles.
Demand side management of customers operating a renewable source in “green bonus” mode
Faktor, Richard ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
This bachelor´s thesis deals with self-consumption management in renewable distributed generation systems. Self-consumption can be defined as the share of the total produced electricity directly consumed by the system owner. Its increase can be achieved by the accumulation of electrical energy or load management, also called demand side management (DSM) through a suitable control and regulation of households appliances and equimpents. The work includes the categorization of appliances in terms of the potential for demand side management and a description and design a concept of domestic load management systems.
Project of PV System for a Commercial Building
Zeman, Daniel ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The main purpose of this work is to describe the basic principles of PV modules and to define the conditions for the construction of PV systems. Define the differences between the various types of PV systems and for the selected object handle system design in accordance with applicable legal conditions. For the proposed technical solution to handle complex energy-economic analysis conducted by the proposal. The work also ncludes procedures for calculating the various parameters that have been known for the correct design of the entire system in a given location during temperature changes and changes in solar irradiance.
