Stabilized operation and short - circuit conditions within E.ON 110 kV power network supplied from Sokolnice 110kV switching station, during the period of 2011

By Jiří Jandora


While changing the connection of the power transformators we have to find out if the powered distribution network can accept this change and if it will fulfil the set conditions. Important is to keep the range of permitted voltage on separate distribution points of this network and to find out proportions on separate circuits. This is connected with a circuit load which cannot exceed its limit (transmission capacity). The network is checked against outages of separate circuits (N-1) and we try to find out if other circuits are not overloaded during the transmission of the outaged circuit’s power. We can also suggest various other possible outages. It is also important to find out whether separate distribution points agree with their short-circuit capabilities. Overall we investigate advantages of this circuit. The theoretical part describes the means of calculation of the network functioning and short-circuit conditions. All the calculated results (dispatcher control system Sinaut Spectrum) for the given circuits of power transformators are processed and evaluated in the practical part of the thesis
