Regenerative Braking Energy Utilization System and Control Strategy for Sectioning Post in Electrified Railway
摘要
Abstract
With the rapid development of electrified railways,some problems of high traction energy consumption and low utilization rate of regenerative braking energy are becoming more and more prominent.In order to effectively improve the utilization efficiency of regenerative braking energy of electrified railway and realize energy saving and emission reduction of electrified railway,a sectioning post regenerative braking energy utilization system and its control strategy are studied.First,based on the analysis of the measured load data of typical heavy-haul and high-speed railways,a sectioning post regenerative braking energy utilization system based on power transfer and energy storage is proposed,and its operating principle is analyzed.In order to ensure the efficient utilization of regenerative braking energy in the system under the complex load condition of electrified railway,a two-layer control strategy with energy management layer and converter control layer is proposed.Among them,the energy management layer accepts the real-time measurement information from the adjacent substation,and calculates the reference power of the system operation based on the substation working condition and system mode management.The converter control layer tracks the reference power given by the energy management layer and coordinates the converters to realize the power flow management of electrified railway.Finally,the correctness and effectiveness of the regenerative braking energy utilization system and its control strategy are verified by simulation.The results show that the proposed sectioning post regenerative braking energy utilization system and control strategy can effectively realize the transfer utilization and energy storage utilization of regenerative braking energy of electrified railway,improve the utilization rate of regenerative braking energy,and contribute to the energy-saving and efficient operation of electrified railway.关键词
