Problems solved by technology

However, each intervention of such a safety system has a considerable influence on the operating parameters of the gas turbine, such as, for example, the output power, the composition of the exhaust gas with regard to emission limit values, or the stable operation of the gas turbine by reducing or interrupting the combustion supply.

Embodiment Construction

[0029] figure 1 A method 100 for controlling a gas turbine is shown, which has a measuring step 101 , a predicting step 102 carried out after the measuring step 101 , and a control step 103 carried out after the predicting step. In the measuring step 101 , state variables of the combustion within the gas turbine are measured. Measuring step 101 can additionally include the measurement of further state variables of the combustion within the gas turbine. The state variables measured in measuring step 101 can include, for example, the temperature inside the gas turbine and / or the air pressure inside or outside the gas turbine and / or the air pressure inside or outside the gas turbine and / or the air pressure inside or outside the gas turbine air humidity and / or vibrations of the gas turbine. The combustion dynamics within the gas turbine can depend on the combustion state within the gas turbine, wherein the combustion state can be determined using the measured state variables. I...

Abstract

The invention relates to a method (100) for controlling a gas turbine, having a measurement step (101), a prediction step (102) which is carried out after the measurement step (101), and a control step (103) which is carried out after the prediction step. In the measurement step (101), a state variable of a combustion within a gas turbine is measured. In the prediction step (102), a future combustion dynamic is predicted using the measured state variable. In the control step (103), a control signal is output using the prediction of the future combustion dynamic.

Description

technical field [0001] The invention relates to a method for controlling a gas turbine as a function of the future combustion dynamics of the gas turbine. Furthermore, the invention relates to a computer program for carrying out the method, a control unit for carrying out the method, and a gas turbine with such a control unit. Background technique [0002] Gas turbines, which are used, for example, in power generation, but also in other applications, represent complex technical systems for which, despite the knowledge of the underlying physical effects, monitoring the processes within the gas turbine is a challenge. The combustion dynamics within the gas turbine lead to partly high accelerations of the gas molecules within the turbine which, if predetermined limit values ​​are exceeded, can lead to damage or destruction of the gas turbine. The combustion dynamics within the gas turbine should therefore be controlled in such a way that such accelerations occur as little as p...
