Title:
GAS TURBINE CONTROL METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/061647
Kind Code:
A1
Abstract:
To restrain combustion vibration more precisely by alleviating the relationship between the composition or heat quantity of the fuel and the combustion vibration characteristic and by grasping the combustion vibration characteristic more accurately. The combustion vibration generated by burner 32 of gas turbine 1 as well as the composition or heat quantity and other plant status amounts of fuel f supplied to the burner are detected. The combustion vibration characteristic is grasped based on the detected values. When the combustion flow rate or air flow rate supplied to the burner is increased/decreased in order to obtain operation condition under which no combustion vibration occurs, the detected values of the combustion vibration as well as the composition or heat quantity and other plant status amounts of the fuel are divided and stored in multiple databases corresponding to the value of the composition or heat quantity of the fuel. In this way, the accuracy of the treatment for approximating the combustion vibration characteristic performed for each data stored in each database is improved. When two databases redundantly store the data in the boundary region of the composition or heat quantity of the fuel, the discontinuity of the model illustrating the combustion vibration characteristic derived by means of the approximation treatment during data processing is reduced.
