Abstract

The invention discloses a method, a device and a system for monitoring the running state of a thermal power generating unit, which are used for solving the problem of inaccurate monitoring of the running state of the thermal power generating unit. The scheme comprises the following steps: acquiring historical load related parameters and actual load related parameters of the thermal power generating unit before a first historical time period; inputting the partial historical load related parameters into a parameter model matched with the thermal power generating unit to obtain predicted load related parameters; taking the historical load related parameters as sample input parameters, and taking the predicted load related parameters and the actual load related parameters as sample output parameters to train a parameter model; monitoring load related parameters of the thermal power generating unit, inputting the parameters into the trained parameter model, and determining the running state of the thermal power generating unit according to an output result of the parameter model. According to the scheme, the sample for training the parameter model is jointly generated by the actual parameters and the prediction parameters, so that the training process has inheritance, the reliability of the parameter model is improved, and the monitoring accuracy of the operation state of the thermal power generating unit is improved.

Description

technical field [0001] The invention relates to the field of state monitoring, in particular to a method, device and system for monitoring the running state of a thermal power unit. Background technique [0002] With the development of intelligent technology for coal-fired thermal power units, a large number of deep learning algorithms have been widely used in thermal power units. The neural network model can be used to predict the output parameters of thermal power units, and then can also monitor the operating status of the unit according to the predicted parameters, and generate early warning information when the status is abnormal. However, with the long-term operation of the unit equipment, due to system transformation, equipment maintenance or equipment performance degradation, the mapping relationship between the input parameters and output parameters of the thermal power unit changes, which leads to the mismatch of the neural network model. The mismatched neural net...
