Abstract

The invention relates to the technical field of nuclear power plant control, in particular to a nuclear power plant digital instrument control verification system and method. The nuclear power plant digital instrument control verification system comprises a simulation model layer, a control logic layer and a human-computer interface layer. The nuclear power plant digital instrument control verification system integrates monitoring of various states, including DCS control equipment states, switch states, and virtual controller and workstation computer states. Comprehensive monitoring is realized, the operation state of the nuclear power plant unit control system can be comprehensively guided, the requirement of fine control is met, and the operation reliability of the nuclear power plant unit control system is improved; and verification is carried out according to nuclear power unit fault information and DCS fault information reproduction faults, DCS configuration is modified, DCS configuration design is perfected step by step, and equipment faults are reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant control, in particular to a nuclear power plant digitized instrument control verification system and a method thereof. Background technique [0002] Due to the advantages of reliability and stability, DCS system has been widely used in nuclear power plants in recent years. However, there are many test blind spots in the DCS system during factory testing and on-site debugging, and it is impossible to completely cover and test system defects. The defects of the DCS system itself and the blind spots of the operation and maintenance personnel's cognition of the DCS system may cause some common operational events in the DCS operation and maintenance process, and in severe cases, it will cause unplanned shutdown. In recent years, there have been many unplanned outages in nuclear power plants of China National Nuclear Corporation. Through analysis, most of the reasons are related to the DCS ...
