Short Circuit Currents in the Sokolnice 400 kV Switching Station with Direct 400/110 kV Transformation Applied
Vojtěch, Pavel ; Špaček, Jaroslav (referee) ; Blažek, Vladimír (advisor)
The destination of this Bachelor´s Thesis is to explore short circuit currents for voltage level 400 kV in the switching station Sokolnice before year 1995 and after this year, when came to installation of the convertor T402 and to voltage direct 400/110 kV transformation applied. The Thesis is detecting at relation as for three-phase short circuit do for single-phase short circuits, for 400/220/110 kV primary transformation variation in voltage and for variation 400/110 kV, the change which came after connection of the convertor T402. In base of this calculation will be explored the short circuit resistance rating switching station in agreement with parameters ordered by the comp. Inc. ČEZ Prague.

Stabilized operation of a 110 kV power line
Leinweber, Luboš ; Paar, Martin (referee) ; Blažek, Vladimír (advisor)
My work is dealing with parameters long high voltage (vvn)110kV with wanted output parameters(voltage rating , cos? , aktive power and size of power line) namely in theoretic part as well as in practic part , which I made from required parameter values of power line. At first I did the approximate calculation by reserve power lines ( T , ? , ? , Steinmetz), by short power line , idle power lines and after that I made perfect conclusion and elaboration by the help of lines. I described these kind of calculation in the theoretic part. I compared the results and I determinated which method was te best.

At first I did the approximate calculation by reserve T-networks ( T , , , Steinmetz), by short T-network , idle T-networks and after that I made perfect conclusion and elaboration by the help of lines.
