摘要： In order to determine a power output by a first energy producer (GT), wherein the first energy producer (GT) is coupled to a second energy producer (DT), a first soft sensor (S1) which is trained to determine an individual mode power value (EL) of the first energy producer (GT) is queried. In a mode combining the first and second energy producers (GT, DT), an individual mode power value (EL) determined for the first energy producer (GT) by the first soft sensor (S1) is read in here. Furthermore, a second soft sensor (S2) determines a first power value (L1) for the first energy producer (GT) and a second power value (L2) for the second energy producer (DT). In addition, a total power (GL) of the energy producers (GT, DT) is determined. According to the invention, the second soft sensor (S2) is trained in such a manner that an individual deviation (DEL1) between the individual mode power value (EL) and the first power value (L1) and a total deviation (DELG) between the total power (GL) and a combination of the first and second power values (L1, L2) are reduced. The first power value (L1) is output.

摘要： In a first training phase, a first neural net (102) is trained using a first training data set. The first neural net and a second neural net (103) are trained in a second training phase using a second training data set, whereby net parameters of the first neural net remain unchanged in the second training phase.

摘要： The invention relates to a method for the computer-aided control of a technical system. In the method, a recurrent neuronal network is used for modelling the dynamic behaviour of the technical system, the input layer of which contains states of the technical system and actions carried out on the technical system, which are supplied to a recurrent hidden layer. The output layer of the recurrent neuronal network is represented by an evaluation signal which reproduces the dynamics of technical system. Optionally, only the state or action variables of the states of the technical system or of the actions carried out on the technical system that influence the evaluation signal can be used as states of the output layer. The hidden states generated using said recurrent neural network are used to control the technical system on the basis of a learning and/or optimization method. The method according to the invention has the advantage that the dimension of the state space of the recurrent hidden layer can be reduced in a suitable way and, nevertheless, the dynamics of the technical system can be modelled well. In this way, control of the technical system that is computationally efficient and accurate can be achieved.

摘要： The invention relates to a method for the computer-assisted monitoring of the operation of a technical system, particularly of an electrical energy-generating installation. In said method, output variables (y(t)) of the technical system are prognosticated using a data-driven model (NN) based on corresponding input variables (x(t)). In addition, a confidence measurement (C(t)) is determined for the 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 on said confidence measurement and prognosticated output variables, an average weighted deviation (E(t)) is determined between the prognosticated output variables (y(t)) and the output variables (y
0 (t)) actually occurring during operation of the technical system. If the average weighted deviation (y(t)) exceeds a predetermined threshold (E
Th ) multiple and successive times, an error in operation is detected in the technical system and, in particular, an alarm is issued. The claimed method allows error operational states to be detected in a technical system in a simple and reliable manner. The method is particularly suitable for monitoring the operation of a gas turbine, in which case the degree of compressor efficiency or the regulated exhaust gas temperature are preferably used as output variables, and the input variables preferably comprise the position of guide vanes in the gas turbine compressor, the ambient temperature, and pressures and temperatures or volumetric flows in said compressor.
