A Novel Simulation of Dynamic Voltages for Multiple-trains in AT-fed Railway Power Supply

This paper presents a novel simulation of dynamic voltages in AT-fed railway power supply. Proposed algorithm is efficient and simple by using the circuit decoupling and iteration method. To verify the proposed method, we used real condition operating data and performed a several case studies. Under train is constant power, we separated each AT section to calculate a loop current, train voltage on any position. Finally, this result utilizes a planning and operation of electrical railway systems.
