The remote controller, when transmitting the operation command next time, transmits the operation command to which an operation time of the last time is added. The protection and control device collates the received execution time of the last time with the operation time of the last time that is stored in the control device itself, and, only when coincident with each other, executes the operation command of this time given from the remote controller.",
