Short-circuit Calculation of Local Distribution Network
 Byrtus, Jiří ; Paar, Martin (referee) ; Topolánek, David (advisor)
This thesis deals with transient phenomena in the electricity grid - especially with short-circuits. First part describes short-circuit types, reasons for their commencement and also consequences of their functioning. The thesis further shows waveforms of short-circuit currents and its components. A method of calculating short-circuits currents, using the constituent systems and the basic equations for calculating short-circuit impedances are also mentioned here. Relations and methods are based on valid standards of IEC 60909 – 0. The second part indicates the calculation of two-phase and three-phase short-circuit currents for specific network of industrial building. This calculation aims to verify the dimensioning of substations for short-circuit currents after connecting a synchronous generator with given power to the main substation.
