Description
Technical Field
The invention relates to the field of nuclear power, in particular to a digital design, a digital design device and digital design equipment of a control system of a nuclear power plant based on a database.
Background
In China and internationally, a large number of control systems built by relays, analog boards and PLCs are still used in nuclear power plants in the seventh and eighth centuries, and the problems of equipment aging, high failure rate, reduced reliability, production stopping of spare parts, difficult maintenance and the like are faced, so that the digital transformation of the existing nuclear power plant control system is very necessary from the aspects of safety and economy.
Taking KCO digital transformation as an example for detail, KCO mainly completes the functions of data acquisition and processing, control, interlocking, protection and the like of a conventional island, and is matched with a steam turbine adjusting, protecting and monitoring system to form an integral conventional island instrument control system, so that the control and monitoring of the steam turbine and auxiliary machine systems are completed. A single unit KCO relates to a 19-face relay cabinet, 62 conventional island process, electrical and other systems.
Although the KCO corresponding technology, electric and other systems also have logic diagrams, the logic diagrams are only functional illustrations, and complete logic functions can be obtained only by matching with electric schematic diagrams and field actual wiring.
The drawing related to the drawing layer comprises: and 1800 drawings such as a logic schematic diagram, an electrical schematic diagram, a BCD diagram, an in-situ box wiring diagram, a KCO cabinet terminal block, a wiring diagram, a cable list and the like are combined into 9000 pages. From the field device perspective, KCO surveys involve 19-sided cabinets, over 54000 cores, approximately 30000 terminals, and thousands of surveys. Because the improved nuclear power plant is built in the seventh eighties of the last century, the electronic and informationized work in the design process of the nuclear power plant is not in place, so that the availability of files and data is poor, and the method is mainly characterized in that: the file is a PDF non-editable and non-searchable version and is unclear. Such huge and extremely complex information amounts are a great challenge for digital modification work, and digital modification is also affected by many existing constraints of the power plant, so that design modes, workload, work difficulty and the like are greatly different from those of conventional designs.
Taking the simplest GSS029SN as an example: the designer needs to consult 5-8 non-editable PDF files, and meanwhile needs to further carry out validity comparison by combining with site investigation information so as to obtain complete and accurate logic functions of the SN. If more complex logic functions (such as linkage, valve pump control, etc.) are to be obtained, the process is more complicated.
