In order to realize the optimal configuration of energy feedback device in urban rail transit,a capacity allocation method of regenerative energy feedback device suitable for multi-train operation is proposed. An equivalent simulation model of subway system with energy feedback device is built with DCTPS and PSCAD software. On this basis,the optimal capacity is calculated by means of genetic algorithm（GA） with the objective of comprehensive benefits of energy feedback devices. The simulation results indicate that the proposed method can ensure the DC voltage security of traction substation,satisfy the needs of traction power supply and regenerative braking power absorption and improve the comprehensive benefits of urban rail transit system.
