The Effectiveness of the Investments for the Systems of El. Power Transmitions
Beneš, Jan ; Kolář, Vladimír (referee) ; Luňáček, Jiří (advisor)
In this master´s thesis I deal most with methods of economical effectivity of investments in electricity distribution and transmition from suppliers to final customers and also with methodology of economical investment effectivity in company E.ON. This proposal of evaluation methodology determines net present value, internal rate of return, and return period of a particular investment project. These surveyed values are determined from yearly net Cash Flow (CF) or from cumulated net CF. I have chosen program Microsoft Office Excel 2003 for its relatively easy input of parameters, simple assemble of calculation algorithm and also for convenient way of calculation results presentation.

Proposal of design and configuration of 22 kV network after installation of 110/22 kV transformation in Brno-Sever switching substation
Mišinger, Ondřej ; Beneš, Jan (referee) ; Blažek, Vladimír (advisor)
The theoretical part of this thesis deals with distribution networks in terms of distribution according to different criteria, describes the main elements of electric distribution networks and their qualities. The following describes the methods of calculating the steady state of electrical networks. These methods are nowadays used as basics for computer programs. In the penultimate chapter of the theoretical part are summarized the principles for the development of present networks and construction of new electrical networks. The aim of practical part of the thesis is to assess the current condition of the network 22 kV in the city of Brno and assess the condition after installation of 110/22 kV transformation in Brno-Sever switching substation. After evaluating the results of steady state electrical network and identifying certain problems is the following aim a proposal of solving problems that emerged in the network. The result should be operational, functional and reliable electric distribution network. This thesis used to calculate the steady state electrical networks by software PAS DAISY Off-Line Bizon V4.
Design of the expansion of 22kV distribution network in a specific area
Řehoř, Jiří ; Beneš, Jan (referee) ; Blažek, Vladimír (advisor)
The aim of this work is the reconstruction and development of the distribution network of DS to ensure electricity supply in the required quality to existing customers and new customers connecting to the planned industrial zone Šlapanice. The first part deals with the inclusion of a distribution network in power system, its distribution and composition. Subsequently, the work deals with the description of the management of distribution networks, cable and outdoor leadership and their parameters. It also contains guidelines for the design of high voltage networks. The end of the first part is devoted to calculating the steady operation of the network. In the second part, the proposed project using the PAS DAISY Off-line v 4.00 Bizon. Based on the available evidence is developed steady state operation. We found that lines are overloaded and need to be strengthened with regard to the development of industrial zones and adjusting the network to ensure safe and reliable operation. The conclusion focuses on the economic evaluation of proposed alternatives.
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.
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.
Altitude meter for RC models
Beneš, Jan ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
Altimeter measures atmospheric air pressure and counts actual model altitude from it. Then sends data to ground module, which shows them on display. Ground module contains USB interface for connecting to PC. It enables upload of flight data and opportunity to show them in graphical representation.
Špica/ Brno, Nové sady 49°11'20.3"N 16°36'29.4"E
Kufa, Ondřej ; Beneš, Jan (referee) ; Palaščák, Michal (advisor)
The aim of the design is to revitalize the area lined by the streets of Nové sady, Úzká, and the Malá Amerika building. This uncultivated place is located quite near to the city center. During the design, the main focus was placed on the potential of the defined area. The new buildings recreate the city block, which is partially opened at the top of the area. In the upper corner of the plot is dominated by the rotating town hall tower. The lower floors of the town hall building are receding backward for the necessity to create a public space under the building, due to a road barrier directly in front of the city hall. The concept of the town hall and the completion of the city block enlivens the locality, brings there new functions, culture, and safety. The proposal counts on planting and recultivating new greenery towards the Malá Amerika building. The whole design thus seeks significantly integrate the new complex with the lowest load on the environment.
