| Abstract: | With the popularization of the energy feedback system in the field of metro,the impact of the feedback electric energy on the safety and stability of the subway power supply network needs to be solved urgently.The simulation model of the inverter feedback system was established firstly,and then the protection configuration scheme of the subway power supply system were introduced.According to the simulation results of the inverter feedback model that could suppress the rise of the voltage and current of the DC traction network and the instantaneous maximum power of the inverter feedback,the protection configuration scheme of the existing subway AC and DC system was improved to ensure the safety and reliability of the subway power supply network. |
