Problems solved by technology

[0004] However, compared with the traditional main control room, the comprehensiveness of the information provided by the sub-system display function designed according to the process system flow in the DCS system is insufficient, and it cannot meet the requirements of simultaneously monitoring multiple system parameters and operating multiple systems during the overall operation process. Equipment requirements do not fully reflect the advantages of the DCS system

Embodiment

[0051] Taking the design and analysis of the display of the water level pressure control function of the pressurizer in the primary circuit, which is an important regulation function of the nuclear steam supply system, as an example, it will be described in detail.

[0052] 1. The main control function modules are established

[0053] During the start-up and shutdown process of the nuclear power plant unit, the unit is in the transition of multiple operating modes, and it is necessary to frequently control the primary circuit pressure, the water level of the pressurizer and other functions. Therefore, it is necessary to design the water level pressure control function display of the voltage stabilizer, so that the operator can quickly and effectively perform large transient operations such as the step-down operation of the primary circuit, the voltage stabilizer building / extinguishing chamber, etc. when the nuclear power plant unit starts and stops.

[0054] 2. Filter and clas...

Abstract

The invention belongs to the technical field of nuclear power design, particularly relates to a functional analysis method of the general operation control display of a nuclear power plant adopting a digital man-machine interface. The method comprises the following steps that a main control functional module in general operation is designed through general operation requirement analysis and functional analysis; and monitoring and control information required for the main operation steps in the main control functional module is reasonably and effectively organized and integrated, and the functional display of the general digital operation control of the main control functional module is developed. Due to the adoption of the functional analysis method of the general operation control display of the nuclear power plant adopting the digital man-machine interface, an operator can conveniently acquire the states of equipment and parameters which are operated or monitored and comprehensively understand the upstream and downstream when in general operation, so that the actuation efficiency is improved, the artificial failure is reduced, and the burden of the operator is reduced.

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 an overall operation control display of a nuclear power plant using a digital man-machine interface. Background technique [0002] The system of PWR nuclear power plant is complex, and its start-up and shutdown (ie: overall operation) are controlled by overall procedures. The operator of the nuclear power plant can use the general procedures to control or change the operating state / condition of the plant. The overall operation of a nuclear power plant requires the operator to follow the required functions, pay attention to the parameters of multiple systems, and operate the equipment of multiple systems. [0003] At present, with the rapid development of digitization, informatization, and automation technology, the nuclear power plant digital instrument control system and advanced digital control room design with digital co...
