This work contains requirements for the design of high-voltage and low-voltage classic and smart wiring. The aim of this work is to implement a project of classic and smart wiring for house and their subsequent comparison. In the beginning is introduction to wiring as such, insight into history, a brief presentation of contemporary species of wiring. The following chapter provides an analysis of high-voltage systems and criteria in its designing, which is based on the currently valid standards. The chapter contains also a brief excerpt dealing with ways of storing wires in buildings and installation zones individual rooms. Chapter of system wiring briefly describes the idea of this kind of wiring and its function. Introduction is focused on explanations of the system wiring, then the chapter directed to a specific producer used in the design of the project itself. In the chapter number five the problem of low voltage wiring and methods for their design are analysed. The following section deals with the design of wiring own project (classic and system) for a family house, designing switchboard, budgeting and technical reports. In conclusion, these two types of wiring are compared in terms of design, project documentation and budget. The practical part is dedicated to creating drawings containing high-voltage and low voltage wiring, switchboard scheme, budget, calculating illuminance and technical reports. The project documentation is discussed further in the technical report.

The aim of this Master’s thesis is the design and reconstruction of the high voltage distribution network for the company E. ON with focus on calculation of the stabilized operation and on the planning of new cable taps from the transformer substation Moravany u Brna. The first part of the theoretical analysis of the work deals with the inclusion of the distribution network into the power system and with principles of development and construction of high voltage networks. The second part includes a general calculation of stabilized operation of the power distribution network and a familiarization with the program PAS Off - Line Bison 4.0. The practical part of the thesis is focused on the calculation of the stabilized operation at the current state of transformer substation Moravany u Brna using the PAS Off - Line Bizon 4.0 V programme. This part also contains the design of six new cable lines which are needed to strengthen the power distribution in the southern part of the city Brno. The closing part of this chapter constitutes of a outdoor and indoor cable line renovation. These cables are connected to the transformer substation Moravany u Brna and a calculation of stabilized operation is also included in this part.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

Proposal of the reconstruction of the distribution network in a specific area
Novák, Vojtěch ; Mrvová, Dana (referee) ; Blažek, Vladimír (advisor)
This diploma thesis is concerned with reconstruction of distribution network in Hruba Vrbka. The diploma thesis is divided in two parts. For better understanding to this issue, the first theoretical part is shortly dedicated to the history of electrical power system, to the several types of distribution network of low voltage and high voltage and their utilization in the area, considering the reliability and the quality of delivery of the electric energy. In this thesis there is mentioned division of distribution grids according to placing of cable lines, according to voltage and according to type of grid connection. Next part of this work is dedicated to the description of overhead lines and cable lines and their characteristics. For the proper concept of the grid we should know some characteristics of the electric line’s proposal: mechanical strength, warming, voltage drop, efficiency, degree of safety and provision of delivery. In the end of the theoretical part there are described methods for calculation of grid’s steady state as a linear task and also non-linear task, elimination of the balancing node, the iterative method, the reduction of external power take-off nodes and the solution of the steady state of the network through the direct current model. The second part of the diploma thesis is concerned with the calculation of the steady state in the village Hruba Vrbka. In this part is also described the KASI program which was used for the calculation of the grid’s steady state. Firstly low voltage grid’s balance in Hruba Vrbka was found out and evaluated and then there were proposed some solutions of the reconstruction for the grid improving. The suggested options of the reconstruction are considered from technical and economical point of view and the best solution is chosen. For this solution there is suggested the protection through program SICHR 9. In the end of this diploma thesis there is checked the load of the high voltage line.

Distribution Network Development and Configuration
Pospíšil, Petr ; Beneš, Jan (referee) ; Topolánek, David (advisor)
The theme of this master‘s thesis is distribution network development and configuration in the part of Brno – Trnitá. There is expected to be investments there in the next few years. The thesis consists of two parts. For better understanding of this problem, the first theoretical part concerns with the description of electrical network (subdivision in accordance with voltage levels, conductor types, network types and other electrical network parts), solution of grid’s steady state (as a linear task and also non-linear task, elimination of the balancing node, the iterative method) and Brno distribution network characteristics. The second part concerns with distribution network development and configuration depending on anticipated load development in Trnitá. The result is proposal for transformer station construction Opuštěná fitted with three transformers of nominal output SN = 40 MVA and network configuration change required both for providing new consumption supply as well as sustaining current one.

Design of technical measures in LV distribution network with a high value of short-circuit currents
Šmehlík, Daniel ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
This bachelor thesis discusses the sizing and the possibility of reducing large short circuit ratios. For a specific scheme of an industrial building, which will be fed from three transformers, the sizing will be done by means of the SICHR program. The specific objective of the technical solution is to be able to use modular circuit breakers with a ripping capability of short-circuit currents up to 10 kA in the terminal switchboards. Another objective of the work is to perform an economic evaluation of the proposed solution, or to optimize the design from the point of view of the economic aspect in meeting the technical requirements.
