Abstract

Provided is a service menu presentation system which: acquires operation data relating to an electric power generation plant; decides which operation pattern, from among a plurality of operation patterns set in advance in accordance with an output mode, is the basis for the operation being indicated by the operation data; calculates, on the basis of the operation data acquired in a certain period, an operation time with respect to each of the operation patterns in the period; determines, on the basis of an operation time ratio in the certain period, an in-period operation pattern of the certain period; and outputs a service menu corresponding to the in-period operation pattern that has been determined.

Claims (29)

1. A service menu presentation system comprising:

an operation data acquisition unit that acquires operation data of an electric power generation plant;

an operation pattern decision unit that decides which operation pattern, among a plurality of operation patterns set in advance in accordance with output modes, shows an operation indicated by the operation data;

an operation time calculation unit that calculates, on the basis of the operation data acquired in a certain period, an operation time for each of the operation patterns in the certain period;

an in-period operation pattern determination unit that determines an in-period operation pattern that is an operation pattern representative in the certain period, on the basis of a ratio of the operation times of the respective operation patterns in the certain period; and

a menu output unit that outputs a service menu corresponding to the determined in-period operation pattern.

2. The service menu presentation system according to claim 1 , further comprising:

an operation pattern output unit that outputs a triangle of which an apex is a point associated with each of the operation patterns together with a mark indicating the in-period operation pattern within the triangle.

3. The service menu presentation system according to claim 1 , wherein, in a case where a difference between operation times relating to two operation patterns among operation times of the respective operation patterns is within a predetermined range, the menu output unit presents a service menu according to the two operation patterns.

4. The service menu presentation system according to claim 1 , wherein the menu output unit presents a service menu corresponding to the number of start-up times within the certain period in addition to the operation patterns.

5. The service menu presentation system according to claim 1 , wherein the operation patterns include a full load operation, a partial load operation, and a governor operation.

6. The service menu presentation system according to claim 5 , wherein in a case where the in-period operation pattern is the partial load operation or the governor operation, the menu output unit outputs the service menu in accordance with an output average.

7. The service menu presentation system according to claim 1 , further comprising:

an operation pattern prediction unit that predicts the in-period operation pattern within the certain period in the future on the basis of operation data in the past in the electric power generation plant.

8. The service menu presentation system according to claim 1 , wherein the menu output unit acquires a first service menu extracted on the basis of a predetermined monitoring item in the operation data and a threshold value determined for each of the monitoring items, and preferentially outputs a service menu equivalent to the acquired first service menu from among the service menus corresponding to the in-period operation pattern.

9. An operation pattern display system comprising:

an operation pattern output unit that outputs a mark indicating an in-period operation pattern that is an operation pattern representative in a certain period, determined on the basis of a ratio of the operation times of a plurality of operation patterns that are determined in advance in accordance with output modes, together with a triangle of which an apex is a point associated with the operation pattern, within the triangle.

10. A service menu presentation method comprising:

a step of acquiring operation data of an electric power generation plant;

a step of deciding which operation pattern, among a plurality of operation patterns set in advance in accordance with output modes, shows an operation indicated by the operation data;

a step of calculating, on the basis of the operation data acquired in a certain period, an operation time for each of the operation patterns in the certain period;

a step of determining an in-period operation pattern that is an operation pattern representative in the certain period, on the basis of a ratio of the operation times of the respective operation patterns in the certain period; and

a step of outputting a service menu corresponding to the determined in-period operation pattern.

11. A non-transitory computer-readable medium storing a program, wherein said program causing a computer to execute:

an operation data acquisition process of acquiring operation data of an electric power generation plant;

an operation pattern decision process of deciding which operation pattern, among a plurality of operation patterns set in advance in accordance with output modes, shows an operation indicated by the operation data;

an operation time calculation process of calculating, on the basis of the operation data acquired in a certain period, an operation time for each of the operation patterns in the certain period;

an in-period operation pattern determination process of determining an in-period operation pattern that is an operation pattern representative in the certain period, on the basis of a ratio of the operation times of the respective operation patterns in the certain period; and

a menu output process of outputting a service menu corresponding to the determined in-period operation pattern.
