Nuclear power station digital regulation installing, debugging and verifying method and nuclear power station digital regulation version upgrading method and platform

Abstract

The invention discloses a nuclear power station digital regulation installing, debugging and verifying method and a nuclear power station digital regulation version upgrading method and a nuclear power station analog machine testing platform. The installing, debugging and verifying method comprises the following steps of: a long directory debugging step of determining a long directory control file corresponding to a long directory according to a control file generated when digital regulation management software creates a directory tree and determining a final node control file generating scheme according to the long directory control file; and an image verifying step of verifying a regulation matched image logic design drawing in a signal forcing and fault inserting manner. The invention solves the problem that the digital regulation management software does not support the long directory; meanwhile, analog machine dynamic verification on an SOP (Standard Operation Procedure) regulation matched image is completed; and on the basis, the digital regulation automatic installing, debugging and verifying method is explored.

Description

technical field [0001] The present application relates to the field of nuclear power technology, and in particular to a method for verifying the installation and commissioning of digitalized nuclear power plant procedures, a method for upgrading digitalized nuclear power plant procedures, and a nuclear power plant simulator test platform. Background technique [0002] With the widespread use of DCS (Distributed Control System) technology in various fields, various nuclear power plants have successively adopted DCS systems. In order to improve the safe operation level of nuclear power plants, there are strict control requirements for various operating states of nuclear power plant reactors. Among them, the accident handling procedure (also known as state-oriented accident handling procedures, SOP procedures) is a standard working document for nuclear power plant operators to control accident units. It plays an important role in controlling accident states, limiting accident c...

Problems solved by technology

[0003] At present, nuclear power plants usually use the application program of digital procedures provided by third parties, such as the TXP system (Teleperm XP, non-safety level control system for nuclear power plants) provided by Siemens, Germany, which is suitable for normal instrumentation and control systems, and the digital procedures provided by third parties usually It is specially developed for the EPR project. In the digital implementation of nuclear power plants, there are many problems such as unavailable links and slow switching speed in the installed digital procedures; moreover, the third party only provides tool software without providing relevant documentation. However, the nuclear power plant has not mastered the technology of self-upgrading of digital procedures, and the upgrading relies too much on third parties, and the continuous upgrading has caused the digital procedures to be out of sync with the paper regulations.

If these problems are not resolved, the digital procedures of the nuclear power plant unit will be unavailable for a long time, and it will also affect the operator’s response to the accident, and then endanger the safety of the nuclear power plant unit
