Load-flow and short-circuit calculation in Sokolnice distribution network over reconstruction

This paper introduces the results of calculation of the steady state (load flow) and short circuit conditions within E.ON distribution network in the Czech Republic. The purpose of this calculation is to determine whether the change in electrical parameters after the reconstruction of the distribution networks substation Sokolnice stay within limits or not. According to these results appropriate technical measures that need to be done before putting into service are discussed. The calculation was done with the use of EON Distribution System Operator software Sinaut Spectrum.
