The advanced traction power supply system (ATPSS) based on power electronic converter can eliminate the neutral sections, which can solve the drawbacks of the existing traction power supply system. Therefore, the ATPSS has attracted much attention. In order to realize the stability and efficiency of the system, proposed an active power coordinated control strategy based on droop control. The topology of the ATPSS is analyzed in this paper, the traditional droop control applied to the ATPSS can achieve equal power output from each substation, but when the locomotive is far from the substation, it will cause more losses on the traction network side. In order to achieve efficiency of the ATPSS, the substation is expected to adjust the output active power according to the position of the locomotive. Most secondary controls require known load conditions to achieve power coordination, but the constantly moving locomotives undoubtedly make communication more difficult. The strategy proposed in this paper can realize the power coordination control automatically without relying on vehicle-substation communication, to meet the required efficiency performance of the ATPSS. Finally, the proposed active power coordinated control strategy has been verified in simulation and experiment.
