FIG. 3 is a flowchart illustrating the operation of the plant management device according to the first embodiment.
The information collecting unit 11 of the plant management device 10 receives the latest KPI of the plant from the plant monitoring device 20 (Step S1). Next, the screen generation unit 12 compares the received KPI with a normal range preset for each KPI (step S2). The screen generation unit 12 generates a KPI screen including each KPI (Step S3). FIG. 4 is a diagram illustrating an example of the KPI screen. On the KPI screen, a plurality of boxes V11 that display KPIs are arranged in a grid. The boxes V11 are vertically arranged for each power generation facility, and are horizontally arranged for each KPI item. At this time, as illustrated in FIG. 4, the screen generation unit 12 sets the box V11 related to the KPI that deviates from the normal range among the boxes V11 included in the KPI screen different from the box V11 related to the KPI that is within the normal range.

  The administrator visually checks the KPI screen displayed on the administrator terminal 40 and determines whether or not the plant is normal by checking for the presence or absence of the highlighted box V11. The administrator can transmit an output instruction of the trend graph screen to the plant management apparatus 10 by selecting an arbitrary box V11 via the input unit of the administrator terminal 40. Specifically, the administrator terminal 40 generates an output instruction of the trend graph screen based on the link information embedded in the selected box V11.

  After transmitting the KPI screen, the instruction receiving unit 14 of the plant management apparatus 10 waits for reception of the output instruction of the trend graph screen from the administrator terminal 40 (Step S5). That is, the instruction receiving unit 14 receives selection of one KPI from the plurality of KPIs included in the KPI screen. When the instruction receiving unit 14 receives the output instruction of the trend graph screen, the information collecting unit 11 transmits, from the plant monitoring device 20, the time series of the KPI for each power generation facility related to the items included in the output instruction and the power generation efficiency of the plant.

  After transmitting the factor candidate screen, the instruction receiving unit 14 of the plant management apparatus 10 waits for reception of a notification instruction of an inspection item from the administrator terminal 40 (Step S14). When the instruction receiving unit 14 receives the notification instruction of the inspection item, the inspection item notification unit 16 notifies the operator terminal 50 of the inspection item according to the received notification instruction (Step S15). That is, the inspection item notification unit 16 notifies the operator terminal 50 of the inspection items (one or more inspection items selected from the list V35 by the administrator) included in the received notification instruction.

  When receiving the notification of the inspection item from the plant management apparatus 10, the operator terminal 50 displays the notified inspection item on the display unit. The operator inspects the plant according to the inspection items displayed on the operator terminal 50 and transmits the inspection result to the plant management device 10.

After transmitting the notification instruction of the inspection item, the inspection result receiving unit 17 of the plant management apparatus 10 waits for the reception of the inspection result from the operator terminal 50 (Step S16). When the inspection result receiving unit 17 receives the inspection result, the screen generation unit 12 generates an inspection result screen including the received inspection result (Step S17). FIG. 7 is a diagram illustrating an example of the inspection result screen. The inspection result screen includes a list V35 of inspection items related to the factor candidates and a display button V37 of the service menu.

In addition, as shown in FIG. 10, the screen generation unit 12 attaches (emphasizes) a marker V33 to a portion related to a factor candidate in the external view V31 of the power generation facility. In the marker V33, an event handler for displaying a pop-up window V34 of an inspection item relating to a factor candidate to which the marker V33 is attached is embedded. The pop-up window V34 includes a list V35 of inspection items related to the candidate factor, and a button V36 for notifying the operator of one or more inspection items selected from the list V35. An event handler for transmitting a notification instruction of the selected inspection item is embedded in the button V36.
The screen transmission unit 13 transmits the trend-factor candidate screen generated by the screen generation unit 12 to the administrator terminal 40 (Step S105). Accordingly, the administrator terminal 40 displays the received trend-factor candidate screen on the display unit of the administrator terminal 40. Displaying the trend-factor candidate screen is equivalent to simultaneously displaying the trend graph screen and the factor candidate screen.

  After that, the plant management apparatus 10 displays the inspection result screen and the service menu screen on the display unit of the manager terminal 40 by the processing from step S14 to step S22.
