Method, device and system for monitoring running state of nuclear power plant

Abstract

A method for monitoring running status of a nuclear power plant comprises: a nuclear power plant real-time monitoring apparatus establishing a dynamic rule base according to historical data of nuclear power equipment in normal running status; the nuclear power plant real-time monitoring apparatus acquiring, in real time, an online running status parameter of the nuclear power equipment; and if the online running status parameter does not match the dynamic rule base, the nuclear power plant real-time monitoring apparatus determining that the online running status parameter is abnormal. In the method for monitoring running status of a nuclear power plant, non-real-time running data and real-time running data of a nuclear power plant system are input in a simulation model to perform a simulation test, thereby implementing effective real-time monitoring on running of equipment of the nuclear power plant. Moreover, further disclosed are an apparatus and a system for monitoring running status of a nuclear power plant.

Description

technical field [0001] The invention belongs to the field of nuclear power plant monitoring, and more specifically, the invention relates to a method, device and system for monitoring the operating state of a nuclear power plant. Background technique [0002] Due to the particularity of nuclear power plants, once a safety accident occurs, it will cause great losses and have a great impact on the human body and the surrounding environment. Therefore, the requirements for its safety are relatively high, and the early warning mechanism for accidents is particularly important. Therefore, It is necessary to monitor the status of various equipment in nuclear power plants in real time, especially the real-time monitoring of the status of major equipment such as main pumps, generators, steam turbines, transformers, diesel engines and evaporators in nuclear power plants, and to monitor them Analysis and processing of state parameters to generate advance warning information.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for monitoring the operation of nuclear power equipment, by establishing a dynamic rule base with historical data in the normal operating state of the nuclear power equipment, and matching and judging the obtained real-time operating data of the nuclear power equipment with the dynamic rule base to solve The nuclear power plant system can only judge whether there is an abnormality in the operation of nuclear power equipment through the early warning threshold, and cannot realize the real-time effective judgment in the operation of nuclear power plant equipment
