Stabilized operation and short - circuit conditions within E.ON 110 kV power network supplied from Čebín 110kV switching station, during the period of 2011
Chrástek, Radim ; Janda, Petr (referee) ; Blažek, Vladimír (advisor)
The aim of this thesis is to project an operation of bridge connection in distribution network in Čebín’s nodal area. The main task is to check a fulfilment of voltage tolerance in distribution substations 110 kV, load transformer control (400/110 kV, 110/VN kV), distribution power line 110 kV control and short - circuit conditions control. Relevant calculations are performed by dispatching control system, which works with the actual parameters of all distribution network‘s 110 kV facilities. The theoretical part of this thesis is devoted to the way of the calculation of stabilized operation and the short-circuit conditions. In practical part, first we perform an analyse of stabilized operation and the short-circuit conditions of distribution network 110 kV in actual operation. Next step deals with bridge connection design and analysing its operation. The operation of bridge connection is verificated even in specific conditions (disturbance state, increased load). The next section evaluates the results of the calculations. First we deal with actual operations evaluation and proposed the bridge connection. In the next section we evaluate the operation of the bridge connection in the specific operating conditions. Finally, we evaluate the losses in the distribution network 110 kV. If the calculations of the stabilized operation or the short-circuit conditions of distribution network discovers that some of its elements are overloaded, we propose changes to ensure safe and reliable operation of the distribution network.

Study of Grade Separated Junction "Kuřim" on Motorway R43
Budík, Ondřej ; Otýpková, Ivana (referee) ; Radimský, Michal (advisor)
This thesis processes a study of grade separated junction „Kuřim“ on expressway R43. The aim of this thesis is to find the solution of connection road II/385 and planned R43 expressway. The interchange is located between the cities Kuřim and Čebín. Construction of northern bypass of Kuřim and usage of this bypass as a connection between R43 and Brno city, before whole R43 is build, is the assumption of this thesis. Thats why solution of the junction forsees the construction and operation in two phases.
