Analysis ofelectrical output from the power plat working in the middle of town
Hrubý, Radek ; Brno,, Luděk Ondroušek - Teplárny (referee) ; Matoušek, Antonín (advisor)
The work focuses on outlet of the electrical power from power plants operating in urban areas. After a short analysis of the general possibility of leading out electric power from power plants of various types, thesis continues to describe of outlet electrical power from PPC Červený Mlýn. Subsequently, are calculated short-circuit conditions in the main switching station. It follows an analysis of power lines. The last part dealt with the issue of reliability of sources in connection with random transition processes in the electrical network and the light of the operational reliability of electrical power equipment.

Implementation of computer models of lines for PLC
Mrákava, Petr ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
The subject of this thesis is to become familiar with the different parameters describing the lines, and the possibility of modeling data and power models. The thesis also outlined the difference in the mechanical structure of different types of cables. The practical part focuses only on the power cables and measure their basic parameters. Then is created computer model which describes the behavior of cable lines at higher frequencies than are primarily intended. The final section is an experimental network created by the PLC for remote reading of electricity meters, and it measured different transmission properties.

The parameters of MV line
Dohnal, Martin ; Orságová, Jaroslava (referee) ; Toman, Petr (advisor)
This work deals with calculation of parameters of power lines and measuring of them. First part deals with calculation of parameters of power lines. Second part deals with measurement of parameters of power lines. Third part deals with measurement of parameters of real MV line using measuring system OMICRON CPC 100 + CP CU1. Measured values are compared with calculated values.

Stabilized operation of a 400 kV power line
Sláma, Jan ; Topolánek, David (referee) ; Blažek, Vladimír (advisor)
This thesis deals with eletrical calculations of long stabilized 400 kV power lines. The main objective is to determine the eletrical parameters of power line beginning in case the parameters of line end are known for various power factors. Also the calculation methods of power lines is generally dealt with. Power-voltage way of computation and a method of exact solution was used for the calculations as to control the results.

Distance Protection for Parallel and Double-Circuit HV Lines
Muhayimana, Obed ; Wannous, Kinan Hasan Wafaa (referee) ; Orságová, Jaroslava (advisor)
Chránění paralelních a souběžných vedení je skutečně problematické z důvodů účinku vzájemné indukčnosti vedení v souběhu, odporu poruchy nebo rozložení zpětného proudu poruchy, které zkreslují impedanci jednofázové poruchy „viděné“ distanční ochranou. Proto současné numerické distanční ochrany nabízí kompenzační funkce, které je možno použít pro korekci charakteristik a výpočtu vzdálenosti poruchy pomocí lokátorů její charakteristice s dostatečnou odporovou rezervou a možnosti nastavení odpovídajícího režimu vypnutí. Tato práce se zabývá problémy, kterým čelí lokátor distanční ochrany při měření a výpočtu vzdálenosti místa jednofázové poruchy, a také mapuje současný stav řešení těchto problémů. Na základě výpočtu parametrů zadaného vedení bylo provedeno zhodnocení možných chyb při lokalizaci jednofázové poruchy a navrženo nastavení distanční ochrany určené k jeho chránění včetně nastavení parametrů určených pro kompenzaci výše uvedených negativních jevů. Bylo zjištěno, že zemnící lana a transpozice vedení přispívají k přesnosti lokátorů, protože nejmenší chyba byla zjištěna v transponovaném vedení se zemním lanem.
