  Similarly, when performing power transmission operations for power system equipment, the person in charge of work or the person in charge of the substation facility confirms the completion of work and reports the completion of work to the person in charge of power system control over the telephone. The person responsible for controlling the power system controlled the operation of the power system equipment (such as power recovery operation).

  However, in such work management using only a telephone, there is a problem that an erroneous operation occurs due to a mistake in communication from the person in charge of the work to the person in charge of power system control. Control operation without knowing that the power system control person in charge has received insufficient confirmation of the details of the accident recovery. There is a problem that power is sometimes transmitted with a work implement attached (such as power recovery operation).

  On the other hand, a power system monitoring and control device that prevents erroneous operation using erroneous operation prevention conditions has been proposed (see, for example, Patent Document 1 and Patent Document 2). However, these power system monitoring and control devices have a problem that it is impossible to prevent an erroneous operation of the power system control manager due to an error in communication from the work manager to the power system control manager.
