Control Strategy of Medium-voltage Feedback Inverter System for Regenerative Braking Energy of Urban Rail Train
摘要
Abstract
In order to effectively utilize the energy generated during regenerative braking of urban rail trains,improve the overall utilization efficiency of braking energy feedback,and fully utilize the interactive effect of braking energy between adjacent trains,when the traction network voltage reaches the inverter starting voltage,the medium-voltage energy-feeding inverter system absorbs the braking energy and returns it to the medium-voltage traction network.A detailed analysis is conducted on the relationship and impact of inverter starting voltage and departure density on the braking energy absorbed by adjacent traction trains and the braking energy fed back by the medium voltage feedback device.The analysis shows that the starting voltage of the inverter feedback device should be reasonably set according to the departure density specified in the train operation diagram,and the overall utilization rate of braking is used as the measure of energy-saving effect.The analysis of the calculation example verifies that the control strategy of the medium-voltage energy feedback system in urban rail trains has a high overall utilization rate of braking energy,providing an important reference for the design of the braking energy utilization system in urban rail trains.关键词
