Proposal of the reconstruction of 0,4 kV distribution network in a specific area
Fojtík, Martin ; Beneš, Jan (referee) ; Blažek, Vladimír (advisor)
This Master’s thesis deals with the problem of distribution electrical network with a focus on solving the steady operation of the electrical distribution network for E.ON Brno - Lisen. The calculation is made by using BIZON PAS Off-Line. The first part of thesis is specialized on the distribution of individual LV and MV networks.The second part of thesis is specialized on the general calculation of the steady operation distribution network and describe criteria for the design and evaluation of this network. In the practical part is calculate existing network in selected area in which is located 53 distribution transformers. In the final part is evaluate the status of existing network and perform design optimization and assessment of this network.

Economical appraising of run the power from cogeneration units to different voltage level
Doležal, Václav ; Macháček, Jan (referee) ; Baxant, Petr (advisor)
The topic of the thesis is economical appraising of run the power from cogeneration units to different voltage level. There is sloves in the text, how and under what conditions we can find an optimal solution for the deployment of cogeneration units to the electricity network. The main criterion is the loss of networks and their economic evaluation. We are a description of the different types of cogeneration units, the economic balance and a treatise on losses in electrical networks.

Load Flow Calculation and Design of Distance Protection Relay Settings of 110 kV Overhead Line
Jasenský, Filip ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
Bachelor thesis load flow calculation and design of distance protection relay settings of 110 kV overhead line acquaints with the theory calculation of steady operation, short-circuit conditions and a proposal setting the distance protection. The theoretical part is made an example of a simple calculation to show leadership methods of calculation. The practical part is a calculation of steady operation and short-circuit conditions. Short-circuit ratios are calculated for a single operation and parallel operation of transformers in Otrokovice. Calculated using the initial shock symmetrical output from the calculation of short-circuit conditions is verified by short circuit resistance of substations. The practical section setting the distance protection ABB REL 316*4 and compensation earth faults. Calculation of steady state and short-circuit conditions designed basic operational state of the network, for which the design of a distance protection relay settings.

Simulation of selected power energy phenomena
Kochánek, Martin ; Bátora, Branislav (referee) ; Šlezingr, Jan (advisor)
This bachelor's thesis deals with the operation of dispersed generation of electricity in the electrical network, the possibilities use of virtual power plant and smart distribution grid. The aim of this work is to build a model of electrical distribution networks in the simulation environment. Connect dispersed generation of electricity to the network and simulate events that may occur in the network and the phenomena to measure and evaluate selected parameters.

Methodology for PLC evaluation in Smart Metering
Rusz, Martin ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
The aim of this work is to acquire basic knowledge about PLC technology and to make a set of measurements focusing on the main parameters of this technology as well as to perform a set of short-term measurements of PLC communication in Smart Metering systems and to design a methodology for testing two real systems. Measurements were made in laboratory conditions on prepared tasks that covered all types of technology, both broadband and narrowband with one or more carriers. In addition, a methodology for testing PLC communications in Smart Metering systems was developed, which was applied to two systems using different technologies. On the basis of the results achieved, it was decided which of the two systems is more suitable for real use according to the methodology and set of short-term measurements.

Smart modul integrated in power plug
Rusz, Martin ; Musil, Petr (referee) ; Mlýnek, Petr (advisor)
The aim of this work is focus on Powerline Communication technology and select a suitable type of broadband integrated circuit for the integration of a broadband communication module into an electrical installation box. In the introduction of this work, the Powerline Communication technology, the principle of communication, individual types of technology, factors influencing the quality of transmission, current possibilities and setting goals necessary for the design of the module are analyzed in detail. The result is a miniaturized functional prototype of a fully integrated broadband PLC modem in a wiring box.

Calculation of HV line distance relay setings
Pustowka, Pavel ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
This work is divided into practical and theoretical part. The first part deals with defective states on ehv lines, especially short-circuits and their calculation, further discusses about distance protections and the theory necessary for their correct adjustment. The second part contains practical calculation of short-circuit conditions and adjustment for distance protection on selected part of 110 kV network, belonging to EO.N company. The result of the work are values needed for adjustment all distance protection in entered part of the network.

Feeding power out of 110/22 kV Moravany u Brna substation
Chromík, Aleš ; Beneš, Jan (referee) ; Blažek, Vladimír (advisor)
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.

Analysis and design of the replacement of the specific overhead line in distribution network
Račuch, Marek ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
The diploma thesis deals with the issue of the reconstruction of outdoor cables of low voltage distribution network in exchange for the cable line. It analyzes the important factors which are necessary for the preparation of the project documentation for the issue of the territorial consent. The thesis is divided into 4 main chapters. After the first chapter there is introduced chapter 2, which shows the differences between cable and outdoor cables with their advantages and disadvantages. Chapter 3 deals with the guiding principles for low-voltage cable design and the types of equipment needed for the proper operation of a particular distribution network while respecting the requirements of valid PNEs and ČSNs. Chapter 4 explains the chronology of the process leading to the formulation of a basic technical proposal, which is further addressed in Chapter 5, which deals with the complete formulation of the project documentation for the issue of territorial consent.
