Description

technical field [0001] The invention belongs to the technical field of nuclear power DCS engineering, and in particular relates to a DCS engineering configuration verification method based on nuclear power simulation technology. Background technique [0002] DCS (Distributed Control System) has been widely used in new nuclear power units, and its function is to control the operation of nuclear power plants and ensure the safety of nuclear power plants. Due to the particularity of nuclear power, it has very high safety requirements, numerous functions, and complex logic, resulting in a relatively large and complex DCS configuration system. Various problems may occur during design, which will affect the progress of the entire project. In order to ensure quality, To guarantee the duration, these logics need to be verified during design and configuration. [0003] The traditional DCS configuration verification test is usually completed on the actual control cabinet. Use the si...

Problems solved by technology

[0004] 1) It requires the support of hardware devices such as controllers, IO boards, buses, and networks, and is highly dependent on devices;

[0005] 2) The verification efficiency is low due to the complexity of hardware operation;

[0006] 3) Frequent operation of hardware equipment will have a certain impact on the service life of the hardware;

[0007] 4) Complex logic debugging (such as PID adjustment, closed-loop logic control, etc.) cannot be performed;

[0008] 5) The verification process is not repeatable;

[0009] 6) The verification object is single, and the DCS configuration test under all working conditions of the power plant cannot be performed

If a DCS configuration problem is found during on-site commissioning, the modification process will be relatively complicated, which will affect the overall commissioning progress
