Title:
GAS TURBINE CONTROL DEVICE AND GAS TURBINE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2023182941
Kind Code:
A
Abstract:
To collect characteristic data which are rich in variations while maintaining a combustion state within a management range.SOLUTION: A gas turbine control device comprises a frequency analysis part, a database, a combustion state prediction part, and a collection amount calculation part. In an operation point which is specified by a process amount of a gas turbine, the frequency analysis part frequency-analyzes pressure in a combustor of the gas turbine, or the vibration of acceleration, and outputs a frequency analysis result. The database stores the frequency analysis result and the process amount as analysis data at each operation point. The combustion state prediction part predicts a combustion state of the gas turbine by using a prediction model which is constructed by using the analysis data. When a search begging condition for regulating the lapse of a standby time which is set on the basis of the past search actual result in an operation point region including the operation point is established, the collection amount calculation part calculates a collection amount which should be added to a control signal of the gas turbine in order to operate the gas turbine at a search candidate point in which the combustion state predicted by a state prediction part falls within a management range out of search candidate points which set operation points as starting points.SELECTED DRAWING: Figure 3
