Title:
GAS TURBINE CONTROL DEVICE AND GAS TURBINE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/243358
Kind Code:
A1
Abstract:
This gas turbine control device is provided with a frequency analysis unit, a database, a combustion state prediction unit, and a correction amount calculation unit. The frequency analysis unit performs a frequency analysis of the vibration of a pressure or an acceleration inside a combustor of a gas turbine, at an operation point specified by a process amount of the gas turbine, and outputs a frequency analysis result. The database stores the frequency analysis result and the process amount as analysis data for each operation point. The combustion state prediction unit predicts a combustion state of the gas turbine using a prediction model that is constructed using analysis data. When a search start condition is met that defines the elapse of a wait time which is set on the basis of past search records in an operation point region including an operation point, the correction amount calculation unit calculates a correction amount to be added to a control signal for the gas turbine in order to operate the gas turbine at a search candidate point, among search candidate points having the operation point as a start point, at which the combustion state predicted by the state prediction unit falls within a management range.
