Functional analysis method for water-supply control of vapor generator by using digital man-machine interface in nuclear power plant

Abstract

The invention belongs to the technical field of nuclear power design, and specifically relates to a functional analysis method for water-supply control of a vapor generator plant by using a digital man-machine interface in a nuclear power. According to the invention, through demand analysis and functional analysis for normal and accident operation, the method abstracts and sorts out a main control functional module contained by the control function of the vapor generator, and reasonably and effectively organizes and integrates monitoring and control information needed for main operation steps in the main control functional module, thereby developing the digital man-machine interface used for water-supply control of the vapor generator in a pressurized water reactor nuclear power plant; thus, operators are convenient to rapidly and accurately obtain the state and the upstream and downstream conditions of operated or monitored equipment and parameters; execution efficiency is improved; human errors are reduced; and the burden of the operators is relieved.

Description

technical field [0001] The invention belongs to the technical field of nuclear power design, and in particular relates to a function analysis method for steam generator water supply control of a nuclear power plant using a digital human-machine interface. Background technique [0002] At present, with the rapid development of digitization, informatization, and automation technology, the digital instrument and control system of nuclear power plants and the design of advanced digital main control room with full digital instrument control technology (Digital Control System, DCS system) as the core have been widely used in nuclear power plants. project. In the digital advanced main control room, the operator completes the operation and control of the power plant through the operator workstation in the main control room. [0003] Steam generator feed water control is an extremely important control function in PWR nuclear power plants. It is used to adjust the water level of the ...

AI Technical Summary

Problems solved by technology

The steam generator feed water control function requires high integration and complex operation requirements, involving multiple systems of the power plant. The relevant subsystem display functions have been designed in the current DCS system, but the information provided by the subsystem display functions is not comprehensive. It needs to switch frequently between the display functions of different subsystems, and cannot meet the requirements of simultaneously monitoring multiple system parameters and operating multiple system equipment in the process of controlling the steam generator feed water, and does not fully reflect the advantages of the DCS system

[0004] On the one hand, compared with the operation of a single system, the control functions required for steam generator feed water control require high integration, complicated operation, and close cooperation of personnel; on the other hand, compared with the traditional main control room, in the DCS system The information provided by the sub-system display function designed according to the process system flow is not comprehensive enough to meet the requirements of simultaneously monitoring multiple system parameters and operating multiple system equipment during the overall operation process
