The invention relates to a method and a device for the natural-language recognition of a vocal expression. A vocal expression of a person is detected and converted into a voice signal to be processed by a voice recognition device. Afterwards, the voice signal is analyzed at the same time or sequentially in a plurality of voice recognition branches of the voice recognition device using a plurality of grammars, wherein the recognition process is successfully completed if the analysis of the voice signal in at least one voice recognition branch supplies a positive recognition result.

An information device for voice-operated support of a user includes a storage medium, a knowledge database, a processing unit, an input device, a recording component, a transcription component, and an ontological analysis component. A signal is detected by the input device and stored by the recording component via the processing unit in the storage medium. The signal is transformed into a corresponding text by the transcription component via the processing unit and stored in the storage medium. The ontological analysis component categorizes the text via the processing unit using the knowledge database and processes the text using the categorization and the knowledge database via the processing unit.

The invention relates to a method for natural voice recognition based on a generative transformation/phrase structure grammar known as GT/PS grammar. According to the invention, a spoken phrase is analyzed for triphones contained therein, words contained in the spoken phrase are formed from the recognized triphones with the aid dictionaries and the spoken phrase is syntactically reconstructed from the recognized words using a grammar. The GT/PS grammar is a novel method enabling target sentences to be placed in said grammar. It uses traditional Grammar Specification Language (GSL), structures said sentences however in an innovative manner. It is oriented towards the rules of phrase structure grammar and Noam Chomsky's concept of generative transformation grammar.

A method is provided for operating a gas turbine in a power station in which limits of the operating concept, which provide limits for optimization of the power station operation in respect of efficiency, service life consumption, emissions and power provision to the grid system, are adapted during operation. In particular, temperature limits and compressor inlet guide vane position limits are varied as a function of the optimization aims. A gas turbine power station is also provided for carrying out the method.

A method for operating a gas turbine includes supplying fuel via at least one control valve regulated using an open-loop control system based on a predetermined load setpoint value. A valve stroke control command (scmd) is generated based on a fuel mass flow control command (mcmd) using a mass flow-valve stroke converter. The valve stroke control command (scmd) is compared with a valve stroke limit value (min{slim1, slim2}) using a variable pressure regulator. A load limit value is generated if the valve stroke control command (scmd) exceeds the valve stroke limit value (min{slim1, slim2}) to reduce the load setpoint value. Operation of the gas turbine is stabilized using a low limit value (xlim) of a pressure drop ratio (x), wherein the pressure drop ratio (x) is a quotient of a pressure drop (dp) which occurs at the control valve and of a pressure (p1) upstream of the control valve.

摘要:
The disclosure relates to a method for operating a gas turbine plant which is supplied with a fuel gas via a compressor station. The compressor station includes a compressor which compresses the fuel gas which is fed via a gas feed line and delivers it via at least one control valve to a combustion chamber of the gas turbine plant. A bypass system is arranged in parallel to the compressor via which fuel gas can be directed in a switchable manner past the compressor to the at least one control valve. An energy-saving operation can be achieved in a simple manner by continuously measuring the fuel gas pressure at the outlet of the at least one control valve. A minimum fuel gas pressure, which is desired (e.g., necessary) for operation of the gas turbine, at the inlet of the at least one control valve is determined from the measured pressure values in each case. The compressor station can be switched over to bypass operation when the fuel gas pressure which reaches the inlet of the at least one control valve via the bypass system is greater than or equal to the minimum fuel gas pressure.
