Analysis and simulation of single phase-to-ground short circuit fault in Van 154 kV substation: An experimental assessment
Abstract
It is necessary to know the short circuit current values of transmission and distribution lines, network
equipment, transformers, breakers, fuses etc. to select and install protection systems in an electrical
network. It is vital to make this selection correctly for safety, continuous operation, keep supplied power
quality in an appropriate level and protect customers from adverse effects of both short circuit currents
and outbreaks. In this paper, single phase-to-ground fault short circuit currents which are possible to occur
in Van 154 kV substation are modelled under MATLAB / Simulink platform. Simulation results are
compared with actual data which is taken from digital relays of substation. Comparison results prove the
validation of simulation system.
