A Study And Design On Data Dsiplay System In The Third Nuclear Power Plant

With the continuous progress of nuclear power plant technology and the digital level increasingly high degree, the data display system in nuclear power station is also increasingly occupied a more important position. As a part of the data display and process system, displays become more and more important. And the displays, alarm process and the computerized procedures which are the sub systems of the data display system are also more and more important. But with the conventional nuclear power plant, due to the number of screens is limited, data display system can not display the parameter information of all nuclear power plant at the same time, the parameters of nuclear power plant can only be displayed in different display screens. At the same time, in order to ensure the plant important parameters can be displayed, don’t let the unnecessary plant data affects the operators’ judgment, the selected principles of the each sub system should be considered. At the same time, the variety of technologies and features of the computer system should be combined to design the most suitable for the third generation of nuclear power plants and related information systems subsystem.In the display design of the process system, the paper first describes the structure of display in the data display and process system, then discuss the selecting rules of the nuclear power plant parameters which should be displayed in the data display and process system, and the principle of the overall layout of the display screen, and the relevant characteristics of the display screen, and then design the static and dynamic elements for the display. At last, according to the relevant requirements and the principle mentioned above, we design the process display for one system and have the preliminary verification and validation work.In the design of the alarm system, the paper first describes the design principles of alarm system of the third nuclear power plant, and then begins the detailed design of the new added function of the alarm system.In the design of computerized procedure system, the paper first mentions the relevant characteristics of operating procedures, and then describes the design principles, and at last give the preliminary design.
