  • Patent number: 5346163
    Abstract: A railway control system for controllably suppressing the maximum output of a railway substation for energy saving in a densified operation territory and, in which a predetermined upper limit value is established in the output of a substation. The output of the substation is always monitored by output monitoring apparatus, and, when the substation output exceeds an upper limit value, control command apparatus transmits a control command signal to any or several of output control apparatus, a train group and an operation administration system. The output control apparatus, train group or operation administration system which receives this signal performs output control or drive force control or both of them, thereby to limit the output of the substation at or below a predetermined value. It thus becomes possible to restrain a temporary output peak of a railway substation and to reduce the installed capacity.
