Optimalizace rozvodu 6 kV na Válcovně předvalků a hrubých profilů.

Abstract

This thesis deals with optimization of network in VHy. The main task of this work is to calculate the short-circuit conditions in the substation R2. The theoretical part of the thesis focuses on the concept of supply of industrial companies in general. In theory, analyzes the structure of the electricity system in detail, it focuses on the analysis and description of the electrical stations. It also deals with substations for high voltage and extra high voltage. Further work theoretically acquainted with the network configuration Energetika Třinec and VHy Třinecké železárny. In the introduction to the practical part describes the procedure for calculating short-circuit current and power substation. Furthermore, there is a calculation of short-circuit currents of the busbar substation R2. According to the calculated values thesis proposes various devices placed in the substation and always in different varieties and from different suppliers. The conclusion is compared before and after optimization substation.
