A reliability data online acquisition, analysis and storage system for nuclear power plant equipment and its storage method

Abstract

The invention discloses a reliable data online collection and analysis storing system for nuclear station equipment and a storing method. The storing system comprises a reliable data collection module, a data screening module, a reliable parameter analysis module and a data storing module, wherein the reliable data collection module consists of an online automatic collection module and an offline manual inputting module; the data screening module receives online automatic collected data and offline manual input data and makes a comparison between collected operator order information and equipment state information to determine whether current information is fault information; the reliable parameter analysis module analyzes failure rate of the equipment at various failure modes; and the data storing module stores collected operation information, basic information and the operator order information and stores the above information for a long term and calculates reliable parameters for the equipment. Effective application expansion of specific reliable data of the nuclear power station can be achieved; and data utilization rate can be enhanced.

Description

technical field [0001] The invention belongs to the field of nuclear safety and reliability analysis, and in particular relates to an online collection, analysis and storage system and storage method for reliability data of nuclear power plant equipment. Background technique [0002] Nuclear safety has always been the foothold and lifeline of nuclear power plant operation. Under the premise of ensuring the safety of nuclear power plants, it is the goal pursued by engineers and technicians to make nuclear power plants run as economically as possible. After the Fukushima nuclear accident, my country changed its nuclear power development policy from positive to cautious. The online risk monitoring and management system for nuclear power plants introduces probabilistic safety assessment and risk management into the operation and management of nuclear power plants. By monitoring the configuration and changes of the operating equipment of the nuclear power plant, it calculates t...

AI Technical Summary

Problems solved by technology

The collection of reliability data can only manually input the operation, status and operation information data of the equipment into the computer. The data collected by the digital control system or information system of the nuclear power plant cannot be directly stored in the computer automatically, and the input data cannot be judged. Authenticity, poor data accuracy

Obtaining reliability parameters from collected sample information is a complex calculation process

At present, the reliability parameter calculation methods adopted in the mainstream foreign commercial reliability analysis and calculation software are relatively simple, and the data sources are complex, so it is impossible to analyze the reliability level of the current nuclear power plant equipment in a targeted manner, and the life distribution of equipment varies greatly. The accuracy of the data is relatively low
