Method and system for setting default value of digital control system in nuclear power plant

Abstract

This invention relates to a method and a system for setting a default value of a digital control system in a nuclear power plant. The method comprises the following steps: S1: sequentially exporting hard-wired signals from a database of the digital system of the nuclear power plant; S2: sequentially detecting the configuration parameters of sensors corresponding to the hard-wired sensor signal in an abnormal state; and S3: writing the configuration parameters in a default value module of the database. The procedure processing is carried out for the selection and setting of the default value of the digital control system in the nuclear power plant, the selection and setting steps of the default value are unified and standardized, thereby saving the selection and setting time and reducing the workload of designers; and simultaneously, the impact of the safety of the nuclear power plant, equipment protection and availability of units and other factors is comprehensively considered, and the selection quality of the default value is optimized.

Description

technical field [0001] The invention relates to a default value setting method and system, more specifically, to a default value setting method and system for a digital control system of a nuclear power plant. Background technique [0002] With the entry of digital instrumentation and control systems into the field of nuclear power, changes in the control and operation methods of nuclear power plants have been brought about. Because nuclear safety is involved, nuclear power process systems and control systems have their particularities, which are usually divided into safety-level platforms and non-safety-level platforms. platform. The signal invalidity judgment and automatic selection functions of the digital control system of nuclear power plants, as well as the softwareization of parameterized module data processing, all make the default value setting in the relay mode of the previous conventional control system no longer applicable to the current default value setting of ...
