Sažetak
The electric railway system represents one of the largest sources of unbalances in three-phase power system. This paper presents the modified three-phase load flow method in order to achieve greater precision in determining the voltage and current unbalances in the observed network. Traditionally, the AC traction loads are modeled in three-phase load flow program as constant two or three equivalent single-phase loads depending on traction transformer connection. The modified Newton-Raphson algorithm, presented in this paper, is based on constant phase-to-phase load modeling. Using this method it is possible to determine bus voltages and power flow in the railway traction system and power system simultaneously. A part of Croatian power system has been used as a test network to present the numerical results of the proposed method.
