Abstract：This paper analyzes the use of regenerative braking energy feeder in a metro, points out the problems of high investment, low utilization rate and large deviation compared with the original design of some line energy feeders, and introduces the configuration scheme of the follow-up line energy feeder in the main line traction substation. Through simulating the working conditions of traction rectifier unit and energy feedback device under braking, operation and startup of multiple trains, the paper analyzes the absorption and consumption of braking energy feedback of vehicles, compares the power and energy saving effect of energy feedback device under different setting schemes, provides design basis for equipment selection and substation layout of energy feedback system, guides the subsequent bidding and procurement of new line equipment, saves civil engineering and equipment Initial investment and operation costs such as installation.
