Description

A nuclear power plant digital intelligent commissioning system TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear power plant digitization, and more particularly to a nuclear power plant digital intelligent commissioning system. BACKGROUND

[0002] A nuclear power plant usually needs to go through feasibility study, design procurement, equipment manufacturing, construction installation, commissioning and starting, operation and decommissioning from the beginning of construction to the end of life. Among them, commissioning and starting is a comprehensive inspection of the equipment, system and structure after installation, to ensure that each single equipment and overall performance of the power plant meets the design requirements and relevant operation criteria. The design, manufacturing, civil engineering and installation defects in the engineering construction stage are mainly found or exposed through commissioning, and if they can be properly solved in the commissioning stage, it will lay a solid foundation for the long-term safe and stable operation of the power plant. At the same time, commissioning and starting is the last process of nuclear power engineering construction, which is a junction between engineering and production, and the types of professional work, the total amount of engineering work and the complexity of the plan during the period will reach a peak.

[0003] The existing commissioning procedure system fails to fully realize the method of design positive integrity verification, which leads to the fact that the integrity of commissioning verification cannot be fully guaranteed when carrying out the commissioning of new reactor types, and there is a possibility of missing verification of design functions, which further increases the potential risk of the unit in service. At the same time, the commissioning test activities are too dependent on the individual ability and quality of the commissioning personnel, so that the safety and quality level of the commissioning of nuclear power projects fluctuates due to the differences in individual ability and quality, the time of personnel training, the periodicity of project construction, and the variability of personnel allocation, and cannot be maintained at a high level. The manual work mode leads to a relatively low production efficiency in the commissioning and starting stage, such as the need for a large amount of manpower and key path period to fill in and publish test reports. The static and isolated commissioning data storage mode can only support simple needs such as consultation, cannot realize data efficiency, and loses the most important commissioning process data. The quality and risk control of the commissioning process only rely on human defense, and the frequency, range and precision are greatly limited, which gradually cannot meet the increasing requirements of the commissioning success rate, safety quality level and other aspects.

[0031] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those ordinarily skilled in the art without creative effort belong to the scope of the present application.

[0032] Referring to FIG. 1, FIG. 1 shows a principle block diagram of a nuclear power plant intelligent commissioning system provided by the present application. Specifically, as shown in FIG. 1, the nuclear power plant intelligent commissioning system comprises a nuclear power commissioning data center 100 (Startup Data Center, SDC), a commissioning navigation system 200 (Startup Navigation System, SNS) and a commissioning testing system 300 (Startup Testing System, STS). The nuclear power commissioning data center 100 is configured to sample, analyze, arrange, construct a data base, display, connect and pass through data and maintain and manage data of commissioning test data.

The commissioning expert system 400 is configured to perform commissioning simulation deduction, early warning of the commissioning process, monitoring of the health status of key commissioning equipment, and fault diagnosis. The nuclear power plant intelligent commissioning system of the present application optimizes the construction of the traditional nuclear power commissioning test procedure, further clarifies the relationship between the design requirements, commissioning methods, program planning, and file writing, ensures that the logic and mapping relationship before and after are clearer and more organized, and on the basis of the traditional TP (Test Procedure, commissioning test procedure), proposes the probability of the commissioning test unit (TU, Test Unit), which is the core element of the digital commissioning test procedure. Compared with TP, TU can better establish a mapping relationship with the design function / item on the one hand, and on the other hand, it can meet the requirements of "standardization" and "modularization" proposed by the digital transformation of commissioning, and play a role of connecting the past and the future. Specifically, to meet the requirements of the digital transformation of commissioning, the content structure of TP / TU is redesigned, as shown in FIG. 2. It mainly reflects in two parts: content writing and calculation configuration. Content writing: the digital commissioning test procedure is based on the ideas of "standardization" and "modularization", and the content structure of the traditional nuclear power commissioning test procedure is redesigned. The optimized program contains nine main articles and four types of attachments.
