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.
Replace of electromechanical protections for terminal protection SPAC 315C system in selected switchboards 6kV on NPP Temelin
JÍŠA, Ivo
In this dissertation I focused on description of engineered replacement of outdated electromechanical protections for new protection terminal SPAC 315C in the 6 kV substations on the nuclear power plant Temelin. I tried to demonstrate practical rationalization of this step, which will lead to better operating safety, increase of control comfort and last but not least will lead to decrease of cost for maintenance of equipment in operation and this will accelerate return of the amount invested.
