Technical design of extensive replacement of overhead lines by HV cables in given distribution area
Bracek, David ; Kolacia, Tomáš (referee) ; Ptáček, Michal (advisor)
This diploma thesis deals with the technical design of extensive replacement of overhead lines by high voltage cables in the given distribution area. In its first part the thesis is focused on the survey of the concerning legislation and technical standards, which must be followed during making technical design documentation. It also mentions the processes which precede the replacement itself. There are also the operational differences between the overhead lines and the high voltage cables in the first part, too. The second part is focused on the technical description of the given area, the technical design of the replacement by high voltage cables and the realization of calculation, which is important as a base for further realization of technical arrangements. The consideration of technical feasibility and economic efficiency are also contained in the second part.

Valuation of utilitie networks - service pipe
Kolacia, Tomáš ; Biolek, Vojtěch (referee) ; Tuscher, Martin (advisor)
This bachelor thesis is concerned with the analysis and the creation of budget indicators for service lines for family houses. The first part is focused on the explanation of basic terms specific for this subject, especially basic information about service lines for family houses and the valuation methods for service lines. The practical part is focused on the creation of basic database of service lines, such as sewer, water and gas pipes, using my own item budget, and the creation of budget indicators for these constructions. In this part, we can find calculated specific indicators that are related to the unit price per meter of the pipe length. In this thesis, budget (price) indicators of ÚRS CZ a.s. and RTS a.s. companies were utilised and for which the pipes were compared on this level. In the last part, I describe a wider classification of constructions, the creation of average prices for these parts and the comparison with a more detailed database, specifically RYRO database used by ÚRS CZ a.s.

Analysis of Smart Grid devices
Kolacia, Tomáš ; Šlezingr, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with smart grids and smart metering in power grids. The first part of the thesis is focused on the comparison between classic topology of electrical grid and smart grid concept including the benefits, which could be achieved. The other parts of smart grid concept are described as well, such as energy storage and electromobility including charging points infrastructure. The second part of the thesis deals with smart metering devices and it describes routing protocols for smart grids. The following chapters summarize practical experience with addressed issues in Europe and in the Czech Republic. The last part is dedicated to evaluation of smart metering implementation in the Czech Republic.

Monitoring in Middle- and Low-Voltage distribution systems penetrated by distributed generation
Kolacia, Tomáš ; Kolář, Vladimír (referee) ; Drápela, Jiří (advisor)
This thesis concerns monitoring in Middle- and Low-Voltage distribution systems penetrated by distributed generation. Monitoring itself means measuring voltages and power flows and sending relevant data to the supervisory system. The first part of the thesis describes distribution systems with differences between individual voltage levels. The following chapter is focused on consequences of high share of renewable energy sources in distribution systems. Most of the problems are partially resolved by technical conditions for connection of the new power sources. However, difficulties with voltage regulation and uncontrolled power flows to higher voltage levels remain. These are the reasons for measuring voltages and currents in medium voltage networks. Second to last subhead of this chapter is dedicated to possible benefits of monitoring. The fourth part of the thesis deals with voltage and current sensors with their advantages and disadvantages. The best suitable devices are chosen in the end of the chapter. It is crucial to mention that sensors are only part of measuring system. Analog outputs from current or voltage transformers need to be converted to digital signal and further processed. After that required quantities are finally sent. Properties of these circuit cards are described in the sixth chapter. Following part aims to define a certain key that will determine the suitable locations for installation of the measurement. The final part of the thesis compares measured voltages and power flows from real 22 kV network with calculated values from computer program PAS DAISY Bizon.

Construction technological project of the production hall in Sudoměřice
Kolacia, Tomáš ; Vlčková, Jitka Laura (referee) ; Venkrbec, Václav (advisor)
The subject of the diploma thesis is construction-technological solution for realization of the production hall with administrative part in Sudoměřice. Parts of the thesis are the technical report for the construction-technological project, a study of the realization of the main technological stages of the building, the solution of the wider transport route links, where I designed and assessed selected transport routes. The other parts of the diploma thesis are design of a site equipment with the technical report of the site equipment, design of the main building machines and mechanisms. The time and financial plans of objects are elaborated, followed by the detail time schedule of the realization of the main building obejct with a workers needs diagram and the item budget of the main building object with the bill of quantities. For the proces of the realization of the reiforced concrete prefabricated construction, the technological regulation for the assembly of elements with usability of the mobile crane, was made. In the diploma thesis, the technological regulation for the reiforced concrete cast-in-place columns and bond beams, was also prepared. Due to the high demands on the quality of the construction, the control and test plans for the assembly of the reiforced concrete prefabricated elements and for the cast-in-place columns and bond beams, were also prepared. Within the environmental protection, the requirements for the certification LEED 2009 Core & Shell, were processed.
