Method for establishing transient intelligent monitoring model of system equipment components of nuclear power unit

Abstract

The present application relates to a method for establishing a transient intelligent monitoring model of a system equipment component of a nuclear power unit, comprising the following steps: determining model measurement points of the transient intelligent monitoring model; obtaining training data of the model measurement points; calculating predicted values of each model measurement point; setting an alarm threshold of the transient intelligent monitoring model according to the predicted values; setting a sampling period of the transient intelligent monitoring model, so as to complete establishment of the transient intelligent monitoring model. The transient intelligent monitoring model can accurately identify state deviation of a monitoring object in a state change process. In addition, the transient intelligent monitoring model established by the present application converts data information into measurement point information, effectively reducing the required training data sample size. Furthermore, the present application uses fault mode data to establish a transient monitoring model of a system equipment component of a nuclear power unit, which can avoid the problem of less data and inability to be directly used caused by monitoring only a single monitoring object.
