  FIG. 1 is a configuration diagram of an example of a power system monitoring and control apparatus according to the first embodiment of the present invention. In FIG. 1, only the part which prevents an operator's erroneous operation is shown. In the first embodiment, the operator's pointing and calling voice that is emitted when operating various power system facilities to be monitored and controlled remotely is compared with the information that the operator inputs from the operation screen. If they do not match, the operation is not permitted and the supply reliability is improved.

  The system operation input means 11 selects a switch to be operated from the operation screen, and the system operation recognition means 12 recognizes data input by the system operation input means 11 as operation switch information. The operation switch information recognized by the system operation recognition means 12 is stored in the operation switch information storage unit 13.

The input voice is recognized as voice input switch information. The voice input switch information recognized by the voice information recognition means 15 is stored in the voice input switch information storage unit 16. The operation content determination means 17 determines whether or not the voice input switch information recognized by the voice by the voice information recognition means 14 and the operation switch information recognized by the system operation recognition means 12 match, and the determination result is determined. Output to the notification means 18. The notification means 18 is composed of, for example, a display device or a voice output device, and notifies the operator of the determination result of the operation content determination means 17. Thus, the operator determines that there is no contradiction between the switch selection information in the switch operation of the distribution system and the switch that the operator has indicated by voice.

  As described above, when performing the switch operation in the power distribution system, first, the voice input means 14 captures the contents instructed to select the switch by voice, and the voice information recognition means 15 recognizes which switch is selected. The recognized switch is stored in the voice input switch information data storage unit 16.
