As an important part of rail transit,the rail transit vehicle base covers a large area and has sufficient lighting conditions,and its photovoltaic resources have great potential for development and utilization.This paper summarizes the current energy use of vehicle base buildings,and analyzes the current AC access mode of photovoltaic power generation in rail transit system.According to the characteristics of building energy consumption of vehicle base,combined with the concept of"DC microgrid"new building power supply and distribution,the architecture of AC-DC hybrid power supply and distribution system of rail transit vehicle base is proposed,and the grid-connected wiring diagram of DC microgrid in the actual project of vehicle base is given.The AC-DC hybrid power supply and distribution system proposed in this project has high energy efficiency and low carbon benefits,which can provide technical support for the green and low carbon development of rail transit.
