The following is an example of the accuracy calculation method. First, the nonconformities (abnormal factors) actually occurring in the past and the operation data at that time are analyzed, and a correlation matrix of the operation data and the factor candidates is created. Next, the probability of each factor candidate can be determined by multiplying the vector indicating the current driving data by the generated correlation matrix.

FIG. 3 is a flowchart showing the operation of the plant management system according to the first embodiment.
The information collection unit 11 of the plant management apparatus 10 receives the latest KPI of the plant from the plant monitoring apparatus 20 (step S1). Next, the screen generation unit 12 compares the received KPI with the normal range set in advance for each KPI (step S2). The screen generation unit 12 generates a KPI screen including each KPI (step S3). FIG. 4 is a diagram showing an example of the KPI screen. On the KPI screen, a plurality of boxes V11 for displaying KPIs are arranged in a grid. The box V11 is vertically arranged by power generation facility and horizontally arranged by item of KPI. At this time, as illustrated in FIG. 4, the screen generation unit 12 is different from the box V11 related to the KPI deviating from the normal range out of the box V11 included in the KPI screen from the box V11 related to the KPI within the normal range.

  The administrator visually recognizes the KPI screen displayed on the administrator terminal 40, and confirms the presence or absence of the highlighted box V11 to determine whether the plant is normal. 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 a trend graph screen output instruction 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 an output instruction of the trend graph screen from the administrator terminal 40 (step S5). That is, the instruction receiving unit 14 receives the selection of one KPI out of the plurality of KPIs included in the KPI screen. When the instruction reception unit 14 receives the output instruction of the trend graph screen, the information collection unit 11 receives, from the plant monitoring apparatus 20, the time series of the KPIs for each power generation facility related to the items included in the output instruction and the power generation efficiency of the plant.

Further, as shown in FIG. 10, the screen generation unit 12 adds (emphasizes) a marker V33 to a portion related to a factor candidate in the external view V31 of the power generation facility. The marker V33 is embedded with an event handler for displaying a pop-up window V34 of an inspection item related to the factor candidate to which the marker V33 is attached. The pop-up window V34 includes a list V35 of inspection items regarding factor candidates, and a button V36 for notifying the operator of one or more inspection items selected from the list V35. The button V 36 has embedded therein an event handler for transmitting a notification instruction of the selected inspection item.
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). Thereby, 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.
