The invention provides a thermal power
plant condenser vacuum degree prediction method based on multilayer LSTM. Firstly, a sample
data set is constructed, input data and output data in a sample are subjected to
standardization processing respectively, then the input data sequentially enter a multi-layer long-short-
term memory neural network, and model training is performed by using an adaptive moment
estimation algorithm; and finally, to-be-predicted data is input into the trained prediction model, and the vacuum degree of the condenser is predicted. According to the method, the long-term andshort-
term memory neural
network structure is applied to condenser vacuum degree analysis,
deep mining of
big data is achieved, the accuracy and speed of
data prediction are improved, and use of
system resources is optimized. According to the two-layer LSTM structure designed by the invention, the model depth can be increased, the model capacity can be increased, the prediction precision can be improved, and meanwhile, the adaptive moment
estimation algorithm is used for optimizing the traditional
gradient descent algorithm, so that the problem of gradient explosion is avoided.
