Dimensioning of Supporting Constructions for MV Overhead Lines
Křepela, Pavel ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The reason of supporting constructions is to transfer all power activity and fulfill all requirements on safe operation of electrical grid. This bachelor’s thesis deals with designing of supporting constructions of the overhead line MV. The main task is to acquire knowledges about single parts of supporting constructions and to describe steps of power effects calculation according to current legislation. The outcome is a simple software application for supporting constructions design from power effect viewpoint.

Influence of All-dielectric self-supporting cable on the mechanics of middle voltage overhead line
Nedoma, Jakub ; Čáslava, Jiří (referee) ; Ptáček, Michal (advisor)
This thesis is focused on assessing the impact of retrofitting dielectric All Dielectric Self-Supporting Cable (ADSS) to existing MV overhead line. This type of optical cable is a means of future strengthening of the communication infrastructure of the distribution network. However, its mechanical properties are significantly different from the properties ACSR cable, due to which its installation can be problematic in terms of meeting the requirements of the PNE 33 3301 standard. In practical part, this work deals with the design of the ADSS installation on the existing MV line and the determination of its impact based on the assessment of the results of this design.

The acquisition and operating costs (efficiency) of different types of HV lines
Veselý, Tomáš ; Reiter, Martin (referee) ; Radil, Lukáš (advisor)
The master´s thesis deals with the evaluation of the efficiency of investment of various types of high voltage lines in terms of capital expenditures and operating expenses. The thesis describes the issue of the regulated environment in the field of electricity, the analysis of the pricing for ensuring the distribution of electricity and the analysis of the capital expenditures and operating expenses of the authorized returns of the distribution company operator. Subsequently, an analysis of the capital expenditures and operating expenses of the overhead and cable lines is processed. The particular components of the operating costs are determined either by annual energy loss per unit of length, an annual hourly labor demand, or an annual cost per unit of length. Another point is the evaluation of the investment efficiency for two different model lines, evaluation of capital expenditures and operating expenses, allowed investment returns and economic evaluation. The conclusion of this pursuit is the comparison of both types of lines, both with the view of capital expenditures and operating expenses, as well as with the view of economic appreciation.
