摘要： A turbo-machine is provided having at least one turbo-machine stage, wherein overload protection of the rotating shaft is provided by the method and, to protect the rotating shaft against overload, a measurement of a torsional stress of the rotating shaft is carried out during operation of the rotating shaft. The torsional stress is measured via a measurement of the torque of the rotating shaft. The torque is preferably measured magneto-elastically. By using the measured torque of the rotating shaft, the development of the torque is forecast. On the basis of the forecast produced, the turbo-machine stage or operating parameters of the turbo-machine is/are regulated. Further a turbo-machine is provided comprising at least one turbo-machine stage which has at least one rotating shaft, wherein the turbo-machine has a device for carrying out the method.

摘要： A magneto-elastic force sensor includes a sensor head (1) that has an emitting coil (9) which generates a magnetic field and at least one magnetic field sensor (11) for measuring a magnetic flux caused by the magnetic field of the emitting coil (9) in a measured object (13). The sensor head (1) also includes a recorder (14) for recording an electrical value that reflects the inductivity of the emitting coil (9) or that is clearly connected to the latter. The magneto-elastic force sensor allows for compensation of a distance dependency in the measurement signal by ascertaining the distance between the emitting coil (9) or the sensor head (1) and the measured object (13) based on the recorded electrical value and by compensating the distance dependency in the measurement signal based on the ascertained distance.

摘要： A method and an assembly for controlling an internal combustion engine having multiple burners is provided. Combustion measurement data is collected in a burner-specific manner for each burner and assigned to a burner identification identifying the respective burner. Performance measurement data of the internal combustion engine is also collected and used to determine a performance value. A machine learning model is trained by means of the combustion measurement data, the associated burner identifications and the performance measurement data, to generate burner-specific control data which optimizes the performance value when the burners are actuated in a burner-specific manner using the control data. The control data generated by the trained machine learning model is output for the burner-specific actuation of the burners.

摘要： A method for detecting damage during the operation of a gas turbine, including the following steps: calculating an average value of individual temperature measurement values over a defined sampling time period from an ensemble of temperature sensors in or on the gas turbine; calculating the individual temperature differences between the average value and the individual temperature measurement values over the defined sampling time period; calculating the individual temperature differences for successive sampling time periods over a defined time interval; creating a first distribution by dividing the temperature differences associated with a temperature sensor for the defined time interval into temperature difference intervals; comparing the first distribution with a second distribution of temperature differences likewise divided into temperature difference intervals; and producing an operation signal on the basis of a negative result of the comparison.

摘要： Various embodiments may include a method for monitoring a hot gas region of a gas turbine comprising: monitoring the region using an imaging radar assembly remote from the region, connected to the region with a hollow conductor. The hollow conductor is closed off at a first end proximate the radar assembly. The radar assembly operates outside the closed-off cavity and the second end opens into the region or is shielded against heat but permeable to radar waves passing into the region. The radar is actuated in time intervals wherein at least parts of the hot gas space are detected by the radar assembly repeatedly at the time intervals. The method includes: feeding acquired image data to an evaluation device; evaluating the acquired image data against a predefined maintenance requirement; and triggering a maintenance alarm as a function of the result of the evaluation.

摘要： A method for computer-assisted monitoring of an electrical energy-generating installation, in which output variables (y(t)) of the installation are prognosticated using a data-driven model (NN) based on corresponding input variables (x(t)). A confidence measurement (C(t)) is determined for respective input variables (x(t)), using one or more density estimators (DE), this measurement being higher, the greater the similarity of the input variables (x(t)) to known input variables from training data with which the data-driven model (NN) and the density estimator (DE) are taught. Based thereon, an average weighted deviation (E(t)) is determined between the prognosticated output variables (y(t)) and the output variables (y0(t)) actually occurring. If the average weighted deviation (y(t)) exceeds a predetermined threshold (ETh) successive times, an error in operation is detected and an alarm is issued.
