Electric submersible pump anomaly detection model construction method and electric submersible pump anomaly detection method

The invention discloses an electric submersible pump anomaly detection model construction method and an electric submersible pump anomaly detection method. The electric submersible pump anomaly detection model construction method comprises the steps that a data set is constructed according to electric submersible pump monitoring data samples; dividing the data set into a training set and a verification set; training a first preset model by using the training set and the verification set to obtain an electric submersible pump monitoring signal reconstruction model; inputting the verification set into an electric submersible pump monitoring signal reconstruction model to obtain a first reconstruction signal corresponding to the verification set; training a second preset model by using the verification set and the first reconstruction signal to obtain a reconstruction error prediction model; determining a reconstruction error standard deviation under a normal working condition according to the verification set a
