Modelling of Bolu - Düzce region 154 kv / 34,5 kv transmission and distribution network at computer

At the present day, energy is the main input of production and it has become much important to use the existing energy sources economically and safely. In our country, it is faced difficuties at the production, transmission and distribution of electrical energy due to the different standarsts used at equipment. It is done re-de working to find the most effective way of correcting these difficulties.Matlab which is a high technology product presents serious possibilities to the user at basic maths and engineering. In this thesis study, Bolu-Düzce region 154 kV/34,5 kV electricity transmission and distribution network is modelled and analysed by using the Simulink toolbox.Using the modelling at this thesis study, power flowing of electricity transmission and distribution is analysed and current-voltage and short circuit flowing values calculated at various baras of Bolu Düzce region. In light of these calculations, the load carrying capacity of current system, relay coordination, control of voltage isolation levels and test results of possible current leakage are obtained.Keywords : Energy, energy transmission lines, power transformers, electricity distribution network, load flowing analysis, short circuit analysis, energy transmission and short circuit analysis whereby matlab and simuling toolbox.
