Kontrola zkratových poměrů v průmyslovém podniku

Abstract

Abstract In his diploma thesis deals with calculation and control of short-circuit conditions at the surface VN industrial enterprise. The issue here is addressed both theoretically and practically. The theoretical part discusses the deeper issues of supply of industrial enterprises, followed by the theory of computational methods for the analysis of short-circuit conditions and a description of the operational involvement of an industrial enterprise networks. In the practical part I solve numerically short ratios for some possible connections operation schemes. In the last part of this work describes the control of MV cables in terms of the effects of short-circuit current.
