An acquisition unit is configured to acquire measurement values of a target device. The measurement values that are acquired include at least a temperature and a flow rate of an input fluid to be input to the target device, and a temperature and a flow rate of an output fluid to be output from the target device. A correction unit is configured to obtain a correction measurement value by which the measurement values are corrected through thermal equilibrium calculations based on the measurement values. A distance calculation unit is configured to calculate a Mahalanobis distance with a factor of the correction measurement value.

Monitoring device, method for monitoring target device, and program

An acquisition unit is configured to acquire measurement values of a target device. A likelihood calculation unit is configured to calculate an occurrence likelihood for each of a plurality of phenomena that are liable to occur to the target device based on the measurement values acquired by the acquisition unit. A table storage unit is configured to store a table in which the plurality of phenomena and occurrence causes of abnormalities of the target device are associated to each other. As estimation unit is configured to estimate the occurrence causes based on the occurrence likelihood and the table.

A notification device is provided with: an abnormality estimation unit for estimating a state relating to an abnormality of a plant and a factor relating to the abnormality of the plant; an item specifying unit for specifying inspection items on the basis of the abnormality of the plant and the state relating to the factor relating to the abnormality of the plant estimated by the abnormality estimation unit; a notification unit for notifying of the inspection items specified by the item specifying unit; a stop-time item specifying unit for specifying the inspection items which should be checked at a time of a stop out of the inspection items specified by the item specifying unit; a check result acquisition unit for receiving a check result for the inspection items notified of by the notification unit; and a stop-time item output unit for outputting the inspection items which should be checked at the time of stop.

Notification device, notification method, and program

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.

Service menu presentation system, operation pattern display system, service menu presentation method, and program

A planning device according to the present invention includes a remaining life specifying unit that specifies a remaining life of a component for a turbine. On the basis of the specified remaining life, a usage plan generating unit generates a usage plan that indicates the timing at which the component is to be incorporated into the turbine, such that the remaining life of the component becomes equal to or less than an allowable error value at a predetermined timing.

Turbine system with planning device generating usage plan of components, and planning method

A turbine analysis device includes a state quantity acquiring unit configured to acquire a state quantity of a turbine, the state quantity including at least a temperature of the turbine. A load specifying unit is configured to calculate a history of a load of the turbine, based on the state quantity. A load and time calculating unit is configured to derive a relationship between the load of the turbine and an operable time when the turbine is operated at the load, based on a designed service life of the turbine and the history of the load that has been calculated by the load specifying unit.

Turbine analysis device, turbine analysis method, and program

An alarm display system includes: a database configured to store a plurality of sets of predetermined events, occurrence probabilities of the events, checking situations of the events, and countermeasure policies of the events in association with the sets; an alarm information acquisition unit configured to acquire alarm information indicating that the events occur in monitoring target devices; a support information addition unit configured to add support information for supporting determination of a countermeasure for the alarm information according to information stored in the database, to the acquired alarm information; and a display unit configured to display alarm display information in which the support information is added.

Alarm display system and alarm display method
