The quality of electric energy in a low voltage public supply networks
Vývoda, Marek ; Pithart, Jan (referee) ; Bok, Jaromír (advisor)
This thesis deals with description of qualitative parameters of supply voltage as well as measurement and data evaluation issues. Theoretical part of thesis describes basic characteristics of low voltage and limits based on standard specification. Next chapter deals with specification of measurement devices used for supply voltage quality measurement. The purpose of these theoretical parts is to introduce reader into supply voltage quality issues and can be used for preparation of measurement and acquired data evaluation under norm ČSN EN 50160 (Voltage characteristic of electricity supplied by public distribution systems). An analysis of real network is the last part of this thesis, in which application of acquired knowledge on assigment of real states of qualitative parameters of supply voltage in network.
Project of Outgoing Transformer Unit for the Photovoltaic Power Station
Hanák, Miroslav ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
This master’s thesis engages in project of outgoing transformer unit for the photovoltaic power station. It describes project and its design documentation what conducts to practising of construction. It has compared investing to more expansive transformer what has lower loss. It describes charges of operation’s transformer in twenty years. It leads project of cable low voltage. It compares whether is better to use aluminium or cupric cables. Project is led with respect for investment costs and minimum of operation loss.
