Here, the network IP address is a number for identifying a device that transmits and receives a transmission packet in a network using the TCP / IP transmission protocol. Hereinafter, it is referred to as an IP address. The switching scenario setting file storage unit 19 stores the output destination information shown in FIG.

  When the selected failure pattern number is “0”, all are normal, and the output destinations are the first to eighth system information display units 31 to 34 and 41 to 44. When the failure pattern number is “1”, since the first system information display unit 31 is out of order, it is output to the command room spare display device 35, for example, instead of the first system information display unit 31. Is set to

  When the failure pattern number is “255”, all of the first to eighth system information display units 31 to 34 and 41 to 44 have failed. At this time, for example, the system display information displayed on the first to fourth system information display units 31 to 34 is displayed on the command room preliminary display device 35, and the fifth to eighth system information display is displayed. The system display information displayed on the parts 41 to 44 may be displayed on the training room preliminary display device 45.

  The output destination information stored in the switching scenario setting file storage unit 19 can be rewritten by the switching scenario creation means 18. The change contents of the output destination information are input by the operator via the input device 17.

In the present embodiment, all failure patterns in which at least one of the first to eighth system information display units 31 to 34 and 41 to 44 fails are created. Here, 256 failure patterns of the eight display units are defined.

  Next, the switching scenario creating means 18 outputs the output destination information to the switching scenario setting file storage unit 19 based on the information input from the input device 17 by the operator or the like, for example, the first to eighth system information display units. The IP addresses of 31 to 34 and 41 to 44 are stored. The output destination information shown in FIG. 3 is created by applying information such as the IP address of the output destination to each of the 256 failure patterns, and stored in the switching scenario setting file storage unit 19.

  When at least one of the first to eighth system information display units 31 to 34 and 41 to 44 fails, the supervisory control computer 1 detects this failure and which display unit is broken. Is identified. Thereafter, a failure pattern is selected by pattern matching from the failure state information stored in the failure pattern file storage unit 16 based on information specifying the failed display unit.

  The supervisory control computer 1 acquires output destination information based on the selected failure state information. Based on the acquired output destination information, the output destination of the system information is designated by an IP address. Next, the system display information displayed by the failed display unit is output to the specified system information output destination.

  For example, when the first system information display unit 31 fails, the supervisory control computer 1 detects this failure and identifies that the first system information display unit 31 has failed. Next, a failure pattern number is selected from the failure state information. In this case, the failure pattern number is “1”.

  The output destination information at the time of the failure pattern number “1” designates an IP address so that the system display information displayed on the first system information display unit 31 can be displayed on the command room spare display device 35. The second to eighth system information display units 32 to 34 and 41 to 44 specify the IP address so as to display the predetermined system display information as it is.

  Thereby, when the display part 31 for 1st system information fails, it becomes possible to display with the display part used as an alternative, ie, the preliminary | backup display apparatus 35 for command rooms.

  In addition, when it takes time to recover the failed first system information display unit 31, the operator monitors the power system in a stable state in the command room 3 and at a predetermined timing in the training room. It is good to move to 4 and to monitor continuously with the display parts 41-44 for the 5th-8th system information.

  As can be seen from the above description, according to the present embodiment, the system display information from the supervisory control computer 1 is transmitted to at least one spare display device arranged in the command room 3, for example, the command room spare display device 35. Can be output. For this reason, even if the command room system monitoring panel 30 breaks down, it is possible to continuously operate the power system monitoring system, that is, to continue monitoring the power system.

  Further, in addition to the case where the command room system monitoring panel 30 breaks down, even when the command room system monitoring panel 30 is newly updated, it is possible to perform monitoring with the standby display device during the system transition period. This makes it possible to monitor a redundant power system and to operate with high reliability.
