MV netwok design for 75 new houses in Damborice
Makuta, Peter ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
Content of this thesis is medium voltage network design for seventy five houses in Damborice. At the beginning author discuss about history of transmission network and distribution network. Next topic is about steady state of network. In theoretic part are different solving methods of linear and non-linear simultaneous equations discussed. Author describes four methods – method of node voltages, elimination of balance node, Gauss-Seidel and Newton method. The electric properties of both the overhead transmission lines and cable lines and their variety are part of this work too. There is purpose, forms and parameters of transformers described. Simplicity of author’s design should reduce the usage of many electrical elements visible to residents.

The comparison of classic AlFe line with ACCC technologies
Hrachiar, Róbert ; Jelínek, Ing Milan (referee) ; Orságová, Jaroslava (advisor)
The diploma thesis deals with the comparison of the conduction with the classic "AlFe" ropes (ACSR technology - aluminium conductor steel reinforced) and the line with the ACCC technology (aluminum core composite core). The first part describes the development of the transmission and distribution network in the Czech Republic. Subsequently types of conductors are described, its construction and main characteristics. The theoretical part also consists of theoretical knowledge about compared types of conductors and knowledge from the field of external lines. During the creation of the theoretical part of the thesis, we gained experience in the advanced functions of Excel, which are later used in practical part. The practical part of the thesis consists of creation of the calculation program itself, instructions and calculation methodology. Included is also an example of use of the program that compars two types of conductors of the same diameter, the same transmitted current and the same weight per unit length.

Mechanical Design of 110 kV Overhead Line
Guliš, Tomáš ; Sýkora, Martin (referee) ; Orságová, Jaroslava (advisor)
When designing overhead lines we must respect many influences that act on it. These are electrical effects and mechanical effects, caused in normal conditions by wind, frost and temperature. This bachelor’s thesis is mainly focused on comparison of calculation of separate load cases and comparison of parameters obtained by mechanical calculation of particular overhead line according to standards ČSN 33 3300 and ČSN EN 50341-1.
