摘　　要：动车组再生制动功率大,再生制动能量回馈于牵引供电系统,将导致牵引网电压抬升,特别当机车处于长、大坡道制动时,经常发生车顶间隙放电、变电所跳闸等现象,影响了机车稳定运行。基于此,以CRH2动车组为例,搭建其再生制动能量计算模型,准确有效地计算在不同制动等级、不同路段再生制动能量。理论计算动车组制动时普通供电方式以及采用同相牵引供电时网压抬升量,分析同相供电装置在解决网压抬升中的应用,通过MATLAB/Simulink仿真验证了此方法的有效性。As the regenerative braking power of electric motor train units（EMUs） is high. The regenerative braking energy feeding back in the traction power supply will lead to the uplift of the traction network voltage, especially in long and large hill slope. The over-voLtage will influence the insulation and safety of electric locomotives. Taking CRH2 EMU as example, the regenerative braking energy calculation model for CRH2 EMU is built. The calculation model can accurately calculate the regenerative braking energy in different braking level and line condition. The voltage rise for EMU braking of ordinary power supply system and co-phased traction power supply system are calculated. Simulation by MATLAB is made. The results verify the effectiveness of the use of co-phased traction power supply system.
