Embodiment 1

[0040] Introduce a specific process of process use case design and test execution. This method of designing test cases for testing can not only test out the problem of inconsistency between configuration and design input, but also detect the problem of function design input. Taking the isolation and commissioning operation of RCV system leakage as an example, a test case based on the actual commissioning experience of the nuclear power plant site is designed. To design test cases, it is necessary to grasp the functions realized by the system under test in the nuclear power plant, and summarize the process requirements of the system under test based on the relevant data of the power plant system and equipment, the relevant data of the commissioning procedures, the relevant data of the maintenance and maintenance of the nuclear power plant, and the relevant standards of the nuclear power plant. . Taking the RCV system as an example, the isolation and commissioning requirements o...

Abstract

The invention belongs to the technical field of automatic control of instruments and meters, and particularly relates to a nuclear power DCS platform test device based on a simulation system and a test method thereof. The device comprises a model server which operates all the system simulation models including chemical and volume control systems; an upper computer of which the function is communication configuration and operates monitoring control frames; and a communication server which realizes data communication between field acquisition controllers and the model server, wherein the port A of the communication server is connected with a lower switch and the port B is connected with an upper switch. The model server is connected with the first port of the upper server, the upper computer is connected with the second port of the model server, and the communication server is connected with the third port of the upper switch. The field acquisition controllers 1-8 are connected with the first to eight ports of the lower switch. The problems that the conventional hardware simulation technology does not perform modeling and cannot realize simulation of the actual physical and technical process control of a power plant can be solved, and the problems that logic testing cannot realize testing according to the technical control requirements can also be solved.
