Abstract

Energy is one of the underlying data of the world's economic and social development. Have a rapid industrialization and urbanization environment, a rapid increase in population, the growth of energy consumption in an indispensable way, make the diffusion of innovation and economical and safe use of the existing energy sources essential. This case depends on the safe and controlled use of energy and the healthy operation of the power systems. The modeling and simulation studies of power systems with computers are being widespread and constituting the infrastructure of the emerging smart grid process. In this study, the modeling and numerical analysis of the interconnected transmission lines from Keban Dam, which includes one of the Turkey's biggest hydroelectric plant, to Elazığ province are carried out with MatlabTM/Simulink software. By implementing realistic modeling, the power transmission network, load flow analysis, voltage and current values in bus bars, short-circuit currents and zero sequence (neutral) currents are numerically calculated. In the study, the maximum short-circuit current which occurs at three-phase short circuit fault for the power network system is obtained as 2 kA. Based on simulation results, the load carrying capacity of the existing system, relay coordination, the control of insulation levels and possible leakage currents are figured out. In the light of the result of the feasibility study, the design of the power system can be realized
