Power plant equipment reliability data automatic statistical system

Abstract

The invention belongs to the field of nuclear power plant equipment reliability and probability safety analysis, and particularly relates to a power plant equipment reliability data automatic statistical system, comprising a server which communicates with the power plant digital instrument control system so as to acquire operation data of power plant equipment needing to be counted. According to the technical scheme, the reliability data of the power plant equipment can be automatically and accurately acquired and counted by means of the platform of the existing digital instrument control system of the power plant. On one hand, the time of manual estimation can be reduced, and a computer automatically obtains and counts completely, and on the other hand, the running time and starting and stopping of equipment can be recorded timely and accurately, and the credibility is greatly improved.

Description

technical field [0001] The invention belongs to the field of nuclear power plant equipment reliability and probability safety analysis, and in particular relates to an automatic statistical system for power plant equipment reliability data. Background technique [0002] Nuclear power plants must regularly submit reliability data reports of power plant equipment to the national nuclear safety regulatory authority in accordance with the requirements of regulations. The report is classified according to the type of equipment, and the operating data and failure data of each type of equipment are counted separately. The operating data mainly refers to the operating time of the equipment and the number of startups, shutdowns, openings, and shutdowns. In addition, the probabilistic safety analysis of nuclear power plants also requires the reliability data of relevant power plants, and converts them into specific data of the power plant, which is used to update the results of the pr...

Problems solved by technology

However, due to the complexity of power plant operation, the actual operation situation is often quite different from the estimate. The number and time of a certain operation stage in an operation cycle are completely inconsistent with the estimate, and each operation cycle may be different.

The operator's log is not necessarily perfect. The start and stop of key equipment will be recorded, but not every equipment that needs to be counted.

As a result, there is a large error in the estimated data, which makes the reliability of the statistical data poor, and reduces the guidance for the operation and management of the power plant.
