Návrh transformovny 110/35 kV

Abstract

The aim of this thesis is to propose solutions in the reconstruction of 110kV substations 110/35kV the reconstruction of the old place. It describes the ways and possibilities of different ways to design substations in upgrading existing or building new power stations and their advantages and disadvantages. It describes the existing transformer equipment, installed devices and equipment, and the reasons for the reconstruction of power stations. Proposal for a 110kV substation is processed according to the methods the facility owner. Individual instruments and equipment is designed according to each manufacturer's catalogs and material standards of investor. Calculation was performed 110kV substation short-circuit resistance and the other labeled equipment sizing calculations for busbar and the negative effects due to short-circuit current. The paper used materials distribution company CEZ, as, SERW, ABB, Pfiffner, AREVA and some older material by CKD, Skoda and Energoinvest.
