摘　　要：针对地铁电阻耗能型再生制动装置不能达到能量再利用的目的,本文提出了逆变+电阻混合型逆变回馈装置用于动力照明的方案,介绍其控制原理、装置构成,建立基于Matklab/Simuink仿真模型。仿真结果表明,加入逆变回馈装置后,制动能置得到充分利用,同时还起到稳定牵引网网压的作用。Due to the inverter device comprised by resistance don＇t make use of the braking energy. This paper proposed the inverter device comprised by inverter and resistance, which is used in the subway power lighting system. The control principle and composition of device is introduced in detail. Also, urban rail train power transmission model is built by MATLAB/Simulink. The simulation results show that braking energy is fully utilized, and traction network voltage is stabilized.
