A control method for on board battery power to compensate the fluctuation of line voltage in case of long distance power feeding in DC electric railway

Abstract

In this paper, a control method for on board battery power to compensate the fluctuation of line voltage in case of long distance power feeding and to manage the energy of battery in DC electric railway is proposed. Then, the control method is verified by numerical simulations. And, we confirm that the control method can compensate the fluctuation of line voltage and manage the energy of battery. In addition, a practical example of the proposed control method, a method of setting control parameters when setting the minimum line voltage is shown.
