Algebraic Equations Comparisons
 Nečasová, Gabriela ; Kunovský, Jiří (referee) ; Šátek, Václav (advisor)
The thesis deals with the topic of comparative calculation of algebraic equations. First it describes the comparison of the overall number of operations at direct and iteration met\-hods, as well as gives concrete examples of the methods and explains solutions of direct and iteration methods. Another part focuses on possible methods of converting systems of linear algebraic equations to the system of differential equations. The end of the thesis describes method of working with TKSL/C, Matlab and Maple. In this thesis, there was designed graphical user interface serving for comfortable communication with TKSL/C programme. Graphical user interface was tested on concrete tasks demonstrating the conversion of system of linear algebraic equations to the system of differential equations.

Steady state and short-circuit conditions within E.ON 110kV power network at parallel operation of transformers T403 and T402 in 400/100kV transformer stations Sokolnice and Otrokovice
 Doležal, Marek ; Foltýn,, Daniel (referee) ; Blažek, Vladimír (advisor)
This master’s thesis is divided into two logical parts. The first part contains theory of calculation of steady state and short-circuits conditions within 110 kV distribution network. Newton’s method and short-circuit current calculation is also explained here. It also deals with classification and aftereffects of transient performance occurring in power networks. The second part contains practical calculation of steady flow and short-circuit conditions at parallel operation of transformers T403 and T402 in 400/110 kV transformer stations Sokolnice and Otrokovice. This calculation is done with program used by system operators called SINAUT Spectrum and consequently analyzed. This part also contains brief description of substations from this region.
