The invention relates to the field of electrical control, and discloses a traction substation control method and device and a medium, and the method comprises the steps: obtaining the operation parameter information of all trains in a traction substation system in real time, so as to determine the port voltage difference of the traction substation system according to the operation parameters of the trains; wherein the operation parameter information comprises train position information and power information; and calling the train power supply system model to process the operation parameter information, and decomposing the train power supply system model by using second-order cone programming to obtain the minimum output power of the traction power transformation system. And the traction substation is controlled to operate according to the minimum output power, so that the regenerative braking energy utilization rate in the train operation process is improved. According to the method, the train power supply system model is called to process the operation parameter information, and the loss power of the train power supply line is reduced. And the model is decomposed by using second-order cone programming, so that the calculation amount is reduced, and the real-time control of the port voltage difference of the traction substation is realized.
