Optimal Design of a Low-Frequency Structural Wiring System
Balák, Dušan ; Slavata, Petr (referee) ; Kadlec, Radim (advisor)
This thesis is concerned with designing and optimizing of a low-frequency structural wiring system in office building. The thesis is divided into two parts, theoretical and practical. Theoretical part is describing factors of designing the low-frequency structural wiring system, with focusing on short-circuits and their consequences on wiring system. Mentioned are optimal economic diameter of electrical cables, purchase and running costs and other factors connected with the optimal designing and protection of electrical devices. In practical part is adjusted, CAD´s system program, assigned a site wiring diagram and allocation of switchboards in the office building. In programs by EATON Elektrotechnika company were developed another parts of project´s documentation. In the Spider program was drew the wiring diagram assigned building and suggested cables and circuit breakers by EATON for correct running in the whole building. In the M-Profil program are designed assigned switchboards and calculated their warming. The motion includes prepared projection documentation, means site wire diagram of the building, schema with evaluations of short-circuits and voltage loss, switchboards design and calculation of their warming.

Analysis of Static and Dynamic Stresses the Existing 110 kV Substation for Short Circuit Strength Increasing
Balák, Dušan ; Škapa, Milan (referee) ; Orságová, Jaroslava (advisor)
This thesis is concerned with static and dynamic stress calculation of busbar and wire conductors in HV and EHV substations according to standards ČSN EN 60865-1 ed. 2 and ČSN EN 50341-1 ed. 2. Calculations are done in program made in MS Excel with consideration to corporate regulations of energetics. In introduction is described the construction of HV substations and methodical step-by-step computation. Practical evaluation is applied to the substation R110 kV Dluhonice, where has to be checked up sufficient short-circuit resistance because of short-circuit strength increasing. At the end is analysed the influence of the spring structure constant on short-circuit strength forces in substation. Highly significant utility is the founded program for HV substations designations.
