Havarijní zálohování uzlových oblastí 110kV distribuční soustavy ČEZ Distribuce,a.s. v oblasti Morava

Abstract

This thesis focuses on the theoretical analysis of the distribution network and substations which are mainly used for substation at voltage level 110 kV. The thesis also describes current state of the CEZ 110 kV network in the region of Moravia as well as the substations in this area. Network models are created in the application SW Daisy both for a normal state and for emergency backup in case of power failure of one transmission transformer or the whole of transmission network. Requirements for suggestion of alternative supply of the affected part of distributor network 110 kV are described for emergency backup. Description of the current state and description of emergency backup is for the every node area (substation). Each model is provided with a description of the manipulation with switches at switch of power lines and bus bars. The results of involvement and results of connection are evaluated.
