Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a facility monitoring system 1 according to an embodiment of the present invention. The facility monitoring system 1 includes a plurality of power generation facilities 7-1, 7-
2,... And the center 3 (that is, the center computer 31)
Are connected by a network 5 such as the Internet.

Although a plurality of power generation facilities are actually connected, only the power generation facility 7-1 will be described below. The power generation equipment 7-1 includes a power generation device 9, a measurement device 11, and a communication device 1.
3. The control device 15 is provided. The power generation device 9 is, for example, a thermal power plant as an internal combustion power generation device. The measurement device 11 is a device that measures output power, voltage, current value, and the like as operation data of the power generation device 9.

FIG. 2 is a view showing operation data of the power generation equipment 7-1 (that is, the power generation device 9). FIG. c) current 27
The time change of the measured value of each is shown.

The communication device 13 is a communication device such as a computer that can be connected to the network 5, and is connected to the above-described measuring device 11. The operation data (measurement result) of the power generator 9 is transmitted to the center 3 via the network 5 as needed.

The control device 15 controls the operation of the power generation device 9 (for example, shuts off in an emergency or changes the setting of the control device). That is, the control device 15
And the operation of the power generation equipment 9 is controlled. Although FIG. 1 shows the communication device 13 and the control device 15 separately, in actuality, the communication device 13 and the control device 1 are not shown.
It may be a single computer having both functions.

The center 3 includes a center computer 31 and a database 33. Center computer 31
Analyzes the measured values (operating data) sent via the network 5. When an abnormality occurs in the measured value, the center computer 31 determines a countermeasure and sends an instruction to the power generation equipment 7-1. The database 33 stores data (for example, location,
Telephone numbers, standards of the power generation equipment owned, standard operation data values, etc.). It should be noted that coping data at the time of occurrence of an abnormality is also recorded in the database 33. In addition, the abnormality handling history data and the like are also recorded, and the abnormality handling history data is searched and used when determining an abnormality handling method.

Next, the operation of the equipment monitoring system 1 will be described with reference to FIG. FIG. 3 shows a flowchart of the equipment monitoring system 1.

In the power generation equipment 7-1, the operation status of the power generation device 9 is measured by the measuring device 11 as needed (step 301).
That is, the operation data (output power 23, voltage 25, current 27
Etc.) are measured from time to time. The communication device 13 sends this measured value (operating data) to the center 3 as needed via the network 5 (step 302).

The center computer 31 of the center 3 analyzes the transmitted measurement values (step 303).
For example, it monitors whether each measured value does not exceed a certain value or a certain amount of change.

When an abnormality is found in the measured value (YES in step 304), the center computer 31 of the center 3
Performs a search for a coping method from the database 33 or a search for abnormal coping history data (step 305), and determines a coping method. Further, the communication device 1 of the power generation facility 7-1
3 is sent an instruction to deal with it (step 306). The abnormality of the measured value is, for example, a case where the output power exceeds a specified value, a case where the rate of change of the current value exceeds a specified value, or the like.

The communication device 13 of the power generation facility 7-1 sends an instruction from the center 3 to the control device 15, and the control device 15 controls the operation of the power generation device 9 (step 307). For example, the control device 15 stops the operation of the power generation device 9. Alternatively, a measure is taken to reduce the output power. If repair is required, the center 3 contacts a repair agent or the like (not shown). The center computer 31 records the above-described abnormality handling history in the database 33 (step 308).

As described above, the power generation facilities 7-1, 7-2,.
In the embodiment, since the center 3 monitors the operation data at any time via the network 5, the monitoring system for each power generation facility can be labor-saving. Further, since the center 3 monitors operation data of a plurality of power generation facilities, it is possible to unify the monitoring criteria for monitoring the operation data.

[0026] In addition, by accumulating past error handling methods in the database 33 and retrieving them when an error occurs, quick and accurate error handling can be performed. Further, when an abnormality occurs in a certain power generation facility, a measure can be taken in which another power generation facility that is considered to be affected is stopped.

As described above, according to the present embodiment, the operation status of the plurality of power generation facilities is monitored via the network, so that labor saving of the monitoring can be achieved. In addition, when an abnormality occurs, the center 3 gives a corrective instruction. At this time, a quick response is possible by searching for a past abnormality handling history.
