Method for diagnosing abnormal oxygen index of condensed water in nuclear power plant

Abstract

The invention relates to the technical field of nuclear power safety, particularly relates to the field of equipment running safety of the moisture index of a secondary circuit of a nuclear power plant, and specifically relates to the diagnosis for the abnormal sodium index of secondary circuit condensed water of the nuclear power plant. The method is characterized by comprising the following steps: 1, acquiring data of sodium and relevant indexes of condensed water in real time; 2, extracting data of sodium and relevant indexes of the condensed water by a system; 3, judging that whether the fault of the sodium index of the condensed water exists or not; 4, determining that whether the relevant index of sodium of the condensed water is abnormal or not and determining the abnormal level; and 5, analyzing equipment and reasons causing the abnormal sodium of a condenser. The diagnosis method provided by the invention achieves the function of fault decision making by operators, can be used for coordinating for multiple departments in the nuclear power plant to cooperatively deal with problems, can be used for guaranteeing the accurate positioning of fault position, fault reasons, treatment measures and department responsibilities, effectively reducing the nuclear power running risk, reducing the running cost, and improving the fault diagnosis accuracy and the running stability of the nuclear power plant.

Description

technical field [0001] The invention relates to the field of abnormal diagnosis of water vapor indexes in nuclear power plants, in particular to the abnormal diagnosis of condensed water and oxygen indexes in secondary loops of nuclear power plants. Background technique [0002] Nuclear power is a safe, reliable, economical, and environmentally friendly energy source. Many countries are vigorously developing nuclear power; however, nuclear power plants are a complex system that involves multiple professional fields and requires the cooperation of multiple departments to ensure the normal operation of nuclear power plants. ; and with the acceleration of the construction of nuclear power plants, the professional and technical personnel of nuclear power plants are scattered, and the new technical personnel have no practical experience, and the ability to judge the abnormality of nuclear power plants is insufficient, and the guarantee for the safe operation of nuclear power plant...

AI Technical Summary

Problems solved by technology

[0004] In order to ensure the safe operation of nuclear power plants, many achievements have been published, such as neural network, genetic algorithm, fuzzy logic and other methods have been applied in the field of fault and abnormal diagnosis of nuclear power plants, and have achieved certain practical results; and the above methods are due to There is a certain risk of misdiagnosis due to high requirements for basic data, so the application and development of the above methods in the field of nuclear power fault and abnormal diagnosis are subject to certain restrictions
