Load Flow Calculation and Design of Distance Protection Relay Settings of 110 kV Overhead Line
Jasenský, Filip ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
Bachelor thesis load flow calculation and design of distance protection relay settings of 110 kV overhead line acquaints with the theory calculation of steady operation, short-circuit conditions and a proposal setting the distance protection. The theoretical part is made an example of a simple calculation to show leadership methods of calculation. The practical part is a calculation of steady operation and short-circuit conditions. Short-circuit ratios are calculated for a single operation and parallel operation of transformers in Otrokovice. Calculated using the initial shock symmetrical output from the calculation of short-circuit conditions is verified by short circuit resistance of substations. The practical section setting the distance protection ABB REL 316*4 and compensation earth faults. Calculation of steady state and short-circuit conditions designed basic operational state of the network, for which the design of a distance protection relay settings.

Calculation of short circuit currents in electtrical network
Reiter, Martin ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
First chapters of my bachelor´s thesis are focused on failures of networks, simple characteristics and description of their potential danger. Next chapters are thoroughly focused on the short-circuit, on the short-circuits graphs, on the circumstances which caused them and on their calculation. Next part is about the example, which is counted by the IEC 60909. First example is simple network. Second example is real distribution network 110kV. We are going to cogitate two involves for the real network and we are going to calculate symmetrical and asymmetrical short circuit current. There is summary of knowledge about the short-circuits and evaluation of the real distribution network at the end of my thesis.
