The invention provides an energy interaction method for an urban rail transit power supply system, and the method comprises the steps: enabling an energy interaction device to form an energy interaction channel through configuring the energy interaction device; monitoring a system power value of a bus of a main substation of the urban rail transit; judging whether the main substation powered by the urban power grid returns energy to the urban power grid or not; and if yes, controlling the energy interaction device to transfer the energy returned to the urban power grid to another main substation or the power supply range of different medium-voltage buses of the same main substation. The invention further provides an energy interaction system and an energy interaction device of the urban rail transit power supply system. According to the invention, the energy interaction channel is established by using the energy interaction device, so that the interactive utilization of the regenerated energy among different power supply ranges is realized, the utilization rate of the train regenerated energy is improved, the return of the train regenerated energy to an urban power grid is reduced, and the operation cost of urban rail transit is reduced.
本发明提供了一种城市轨道交通供电系统能量交互的方法,通过配置能量交互装置,使其形成能量交互通道;监测城市轨道交通主变电所母线的系统功率值;判断所述由城市电网供电的主变电所是否向所述城市电网返送能量;如果是,则控制所述能量交互装置将向城市电网返送的能量转移至另一座主变电所或者同一主变电所的不同中压母线的供电范围。还提供了一种城市轨道交通供电系统能量交互系统和能量交互装置。本发明使用能量交互装置建立的能量交互通道,实现再生能量在不同供电范围之间交互利用,提高了列车再生能量的利用率,减少了列车再生能量向城市电网的返送,降低了城市轨道交通运营成本。
