Title:

METHOD AND SYSTEM FOR INTELLIGENT MONITORING OF STATE OF NUCLEAR POWER PLANT

Document Type and Number:

WIPO Patent Application WO/2021/172723

Kind Code:

A1

Abstract:

In order to provide a method and a system for monitoring a state of a nuclear power plant capable of reducing a state prediction error of a sensor during startup, full power, and shut down operations of a nuclear power plant, and of providing an early warning, without an error alarm, by remotely and automatically diagnosing the state of a sensor, device, system, and power plant, the present invention comprises: a first layer that compares a sensor measurement value and a device measurement value with predicted values so as to detect anomalies of the sensor and the device; a second layer that classifies a type of the sensor and diagnoses the presence or absence of an anomaly of the sensor on the basis of an anomaly value of the sensor provided from the first layer; and a third layer that diagnoses the state of the nuclear power plant on the basis of detection and diagnosis results for the sensor provided from the first and second layers and an anomaly result for the device provided from the first layer.
