摘要：In order to prevent regenerative energy failure for the metro-trains, this paper proposes a new circuit configuration of an energy storage systems. The system enables improved performance of the powering and the regenerative braking at the high speed region without regeneration failure. Suggests a novel energy management control algorithm for metro trains based on acceleration measurement and estimation. The energy management control is integrated with the motor drive control. The algorithm is based on two nested loops on voltage and current of SC. The voltage and current references are calculated on the basis of the estimation of the train inertial force and motor torque. A simplified mathematical model of the whole electrical drive has been developed, the main features of the circuit configuration and the control strategy have been presented. Numerical simulations show the efficacy of suggested configuration and the energy saving obtained for metro trains. Experimental tests made on an electromechanical simulator fully confirm theoretical results. ? 2014 IEEE.
