PROBLEM TO BE SOLVED: To provide a railway DC voltage control system capable of performing energy saving by improving a regeneration rate of a train while appropriately controlling a DC voltage in a DC substation and in a feeding section or a feeding tie post provided between DC substations or in a regenerative power absorption device. ! SOLUTION: A feeding tie post 5 or a feeding section 7 provided between substations 3 of railroads of double tracks or more or a regenerative power absorption device 9 includes a control device 53 for controlling activation/opening of a switchgear 51. In the case where a train load is heavy and an average DC voltage is reduced, the control device supplies sufficient power by activating the switchgear 51 and connecting up and own tracks and in the case where the train load is small and the average DC voltage rises, the control device 53 improves the regeneration rate of the train by opening the switchgear 51 and reducing the average DC voltage. A constraint for operating the |
