Automatic Voltage Control of Distributed Generation in the E.ON Medium Voltage Grid
Skoupý, Martin ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
Content of this master`s thesis is theoretical introduction of the power factor, reactive power and voltage control of decentralised sources of the high voltage in the E.ON distribution network. Furthermore, the thesis deals with possibilities of regulating the power factor and reactive power, carried on above-mentioned resources, in other to stabilize the voltage and overflow control of the reactive power to higher voltage level. The practical part describes how the automatic power factor and voltage control had been put into action by central management control within the headquaters dispatching systém of the company. Following chapter acquaints a reader with information of how the automatic power factor and voltage control had been tested and how it is utilized in practice. In the conclusion the work summarizes results and effects of the power factor regulation and voltage control to stabilize the voltage and the overflow of the reactive power in the E.ON network.
Molecular-biological characterization of Potato virus M and Potato leafroll virus
Vaculík, Petr ; Čeřovská, Noemi (advisor) ; Fousek, Jan (referee)
The main aims of diploma thesis were: 1) The sequence analysis of the Czech isolate of Potato virus M (PVM) VIRUBRA 4/009 and phylogenetic analysis of PVM coat proteins sequences 2) The bacterial expression of recombinant triple gene block protein 1 (TGB1) of PVM derived from the Czech isolate VIRUBRA 4/007 3) The construction of expression cassette of Potato leafroll virus (PLRV) coat protein and its transformation into A. tumefaciens for transgenic PLRV resistant plant formation In theoretical part of the thesis the taxonomic classification, morphology, genomic structure and virus transmission are discussed. Furthermore, the main rules concerning the bacterial expression of recombinant proteins and construction of transgenic plants using A. tumefaciens are described. Methodical part is devoted to description of generally used molecular biological and immunochemical methods. The following results were obtained in the thesis: The complete nucleotide sequences of open reading frames coding for three movement proteins (Triple gene block -TGB), coat protein and NA-binding protein of PVM isolate VIRUBRA 4/009; phylogenetic analysis was performed; the TGB1 protein was expressed in bacterial cells and will be used for polyclonal antibodies raising. Finally, the expression cassette containing the PLRV...
Proposal to upgrade the wastewater treatment technology in the selected Wastewater Treatment Plant
Líkař, Vladislav ; Vaculík, Petr (advisor) ; Malaťák, Jan (referee)
This thesis deals with the issue of waste water treatments from small sources of pollution. At the beginnig, there are characterized wastewater and important indicators for measuring the concentration of pollution, then this thesis describes the different technologies and technological equipment used in the treatment of wastewater from small sources. In the practical part of the work is designed to upgrade the technological part for processing waste water for area businesses METRO NITRA. The first part describes curent conditions of selected wastewater treatment plant. Next part describes in detail the proposed technological part and evaluation samplings. Later in this chapter is described the economic value and the expected schedule of work.The aim is to design WWTP upgrade with the technical and the economic assessment.
Integration assitive systems with IH&S
Čáslavková, Andrea ; Votruba, Zdeněk (advisor) ; Vaculík, Petr (referee)
The thesis is focused on the elderly population - seniors and their safe living in their own environment. The main target is to improve their quality of living, independence and self-sufficiency through assistive and security services. We will acquaint with the various organizations that deal with this issue. As an example we will show you a senior´s flat that is equipped with points and elements falling into these technologies and overall assessment.
The use of solar collectors in the Czech Republic
Kočka, Jan ; Kic, Pavel (advisor) ; Vaculík, Petr (referee)
The aim of this thesis was to approach the market of solar systems in the Czech Republic and the subsequent design of the solar system in the selected object, in this case RD Divišov. In the chapter Overview of the findings from the literature there are outlined the general knowledge about the Sun and the use of solar radiation. In addition, this chapter provides a general overview of solar collectors followed by the approach of the necessary elements for the functioning of the solar systems. In the chapter Default conditions of the solved object there is characterized the selected one, and there is described the current system in this object. Chapter The design of the solar system in a given object includes the proposal of individual elements of the solar set for water heating. There are compared variants with different demands, different input parameters on the basis of values and graphs chosen the most efficient option for this project. At the end, the economic evaluation of the proposed system with the subsequent comparison with the current system and possible return. The work is ended by summarizing of the whole issue.
