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.

Universal computer program for energy calculations of power supply of DPMB tracks
Mai, Jaroslav ; DPmB, Jiří Šebor - (referee) ; Matoušek, Antonín (advisor)
This thesis dwells on program creating in program environment Excel, in accordance with submission from submitter. Program is going to be able solve all required values. This thesis has four parts. First part is oriented on problems of urban mass transportation a methods of specific energy consumption. Second part contains program flowchart and program description. Third part contains theoretical solution of specific energy consumption and theoretical comparison of computing methods. Last part contains numerical substitution in an equations and calculating of their values.
