Návrh zapojení distribuční soustavy po dobu plánovaných rekonstrukcí zařízení 110 kV

Abstract

The aim of this thesis is to design and verify the possibility of calculating the involvement DS during the reconstruction of 110 kV equipment. Reconstruction, which the company plans to CEZ Distribution, a.s. in the region of Moravia will take place in 2014 - 2016 years. The theoretical part is an allocation of electricity networks, including the required aspects of their sizing. There are discusses the legislative framework for quality of electricity supply with regard to the interruption of transmission or distribution of electricity, including indicators of continuousness of transmission or distribution. They are briefly described here PPDS and PPPS. The practical part describe and the selected part network of the 110 kV in which they will take place individual reconstructions. Are performed and compared to calculations of steady state before and after changing the connections required for each reconstruction. The calculations were carried out in the PAS DAISY Off - line, based on the input file based on measurement values of 16 January 2013. On the computed values is checked whether, there is no overloading of lines and transformers, if there is a change concept of distribution system (compliance criteria n-1). At the conclusion was performed checkup possibilities of current implementation of reconstruction.
