Problems solved by technology

This is very expensive in terms of computational technology, since especially in the case of open-loop control, even in operating states of the gas turbine in which there is no possibility of combustion instabilities at all due to the operating conditions, the Possibilities are also taken into account consecutively

Embodiment Construction

[0026] figure 1 The gas turbine 1 is shown in longitudinal partial section. The partial section shows only the upper half of the gas turbine 1 . The gas turbine 1 has in its interior a rotor 4 mounted rotatably about an axis of rotation 2 (axial direction) and also referred to as a turbine rotor. Arranged first one after the other along the rotor 4 are the intake housing 6 and the compressor 8 . Air is directed from the outlet of the compressor 8 to two silo combustion chambers 10, which are only generally shown in figure 1 and is not presented in more detail below. The silo combustion chamber 10 is followed by a turbine 12 and an exhaust gas casing, not further described.

[0027] Although the method described below is described with reference to a gas turbine 1 with a silo-type combustor 10 , it can equally well be applied to a gas turbine 1 with a differently configured combustor. The following statements therefore also apply to gas turbines 1 having, for example, annu...

Abstract

The invention relates to a method for regulating a gas turbine (1). The fuel quantity supplied to the burners of the gas turbine (1) is regulated using a target value (Tsoll) for the corrected turbine outlet temperature (TATK). A stable operation of the gas turbine is to be allowed with a particularly high degree of efficiency and a high output at the same time. For this purpose, the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is set using a value (W) which characterizes the combustion stability in the burners, wherein the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is set additionally using the surrounding temperature (TV1). Furthermore, the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is set only below a specified surrounding temperature (TV1) using the value (W) which characterizes the combustion stability in the burners.

Description

technical field [0001] The invention relates to a method for regulating a gas turbine, wherein a target value for correcting the turbine outlet temperature is used to regulate the quantity of fuel supplied to a burner of the gas turbine. Background technique [0002] A gas turbine is a continuous flow machine in which pressurized gas is expanded. It consists of a turbine or expander, a compressor connected upstream and a combustion chamber connected in between. The principle of action is based on a cyclic process (Joule process): the latter compresses the gas by means of the blades of one or more compressor stages, this is then mixed in the combustion chamber with a gaseous or liquid propellant, and it is ignited and burned . [0003] This results in hot gases (a mixture of combustion gases and air) that relax in the downstream turbine section, where thermal energy is converted to mechanical energy and drives the compressor first. The remainder is used in turboshaft engin...
