PURPOSE:To estimate substation power to be supplied a specified time after the present time and to suppress the substation power to a specified power, concerning a levitation system railway provided with a substation which supplies power to a feeding range to be changed in accordance with the running position of a train. CONSTITUTION:The controller has a power supervising means 1 for detecting the quantity of the power of a substation 7, a train position detecting means 2 for detecting a train 8 in a current feeding range and the position of the train 8, a current feeding border estimating means 3 for estimating the position of a current feeding border for the train 8 to pass by information from this train position detecting means, and a power estimating means for estimating the quantity of power required until the train 8 passes the current feeding border, from power at the present point of time. Besides, it has a current feeding border correcting means 9 for correcting the current feeding border so as to narrow a current feeding range, when the estimated power exceeds a specified power, or a target speed correcting means 10 for reducing the speed of the train. |
