Nuclear power station power loss test management system

Abstract

The embodiment of the invention provides a nuclear power station power loss test management system, and the system comprises a data management module which is used for obtaining the real-time test data of a nuclear power unit in a nuclear power station system power loss test; a simulation deduction module used for performing nuclear power station system power loss test simulation according to thereal-time test data to obtain a simulation result; and a fault diagnosis module used for comparing the simulation result with a power loss test acceptance criterion of the nuclear power station systemto obtain a fault diagnosis result. According to the embodiment of the invention, real-time data of the nuclear power unit is acquired to realize simulation deduction of power switching and power loss test consequences, online early warning, rapid fault diagnosis and guidance of processing work. Behavior of test operators is standardized, safe and reliable operation of the nuclear power unit is ensured, availability and reliability of related equipment are improved, equipment fault consequences are controlled, the nuclear power unit fault duration time is prevented from being too long, and safety accidents caused by fault handling activity errors are also avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of nuclear power engineering, and in particular to a management system for power failure tests of nuclear power plants. Background technique [0002] The special tests for nuclear power plants include switchover of factory power supply (BAS for short) and power failure test for control and instrument power (COC for short). The impact of two types of design basis accidents, failure and control power failure, on the overall power plant. [0003] BAS and COC tests involve general, nuclear island, conventional island, electrical, and instrument control disciplines. The time span is from cold test to grid connection. Test personnel are required to have comprehensive technical knowledge and rich field experience. [0004] At the same time, the test window is short, the amount of original data is large, and the result analysis is complicated. However, the test results restrict important nodes...

Problems solved by technology

[0004] At the same time, the test window is short, the amount of original data is large, and the result analysis is complicated. However, the test results restrict important nodes such as hot test and charging, and put forward extremely high requirements for test risk control, test report quality and progress.

[0005] With the increasing number of commissioning and starting units, the risk control and experience feedback data of power failure test increase rapidly, and are scattered among various projects. The large amount of data and scattered storage make the effective application of data a new problem.

[0006] At the same time, due to the short response time of the test process and the complexity of data analysis, the requirements for the response speed of emergency time analysis are high. Therefore, transient events of equipment caused by improper emergency operation of the test occur from time to time, exposing existing power failure analysis and operation accident procedures in the debugging stage It has great limitations, so there is an urgent need for real-time simulation and online diagnosis and early warning of the test process
