Description

technical field

The invention belongs to the technical field of nuclear power, and in particular relates to a nuclear power plant DCS function verification method, device and system.

Background technique

With the development of digital technology, the distributed/digital control system (Distributed/Digital Control System, DCS) system has been gradually applied to the control field of nuclear power plants, replacing the previous analog instruments. With the rapid development of nuclear power plant DCS simulation technology, DCS simulation has entered a new era. On the one hand, the update of DCS simulation technology in nuclear power plants comes from the strong demand in reality, such as the need for more powerful and complex DCS functions, and the need for configuration training for control personnel; Simulation needs, etc. Therefore, the nuclear power plant DCS simulation system puts forward higher requirements on the simulation technology from the aspects of function, target and scope. On the other hand, the rapid development of computer technology, communication technology, network technology, visualization technology, virtual reality technology and other modern information technologies has provided rich means of realization and strong support for the virtual verification of nuclear power station DCS.

The instrument and control systems of many domestic nuclear power plants in service are undergoing digital transformation. Newly built nuclear power plants generally adopt digital instrument and control systems, and an important feature of digital instrument and control systems is the use of distributed instrument and control systems. The reliability of the DCS system is directly related to the safety and economy of the nuclear power plant. Therefore, the functional test and verification of the DCS system has become an important task. At present, the DCS system function test and verification work of domestic nuclear power plants is generally packaged to the DCS manufacturer, and the owner is responsible for tracking the verification process and acceptance, or engineers manually check the program, resulting in a large workload and prone to human errors. In order to improve the verification technology of DCS control in nuclear power plants, the virtual DCS scheme can be used to verify the rationality of the internal movable parts of DCS and the distribution of DCS functions. Currently, DCS verification is mainly through manual input and configuration failures, resulting in low verification efficiency. Considering the safety of the DCS of nuclear power plants, the logic of the same important function cannot be allocated to the same card, the functions between sequences need to maintain relative independence, and important functions need to be configured redundantly. How to realize efficient and fast nuclear power plant DCS verification and avoid verification errors caused by human error to meet actual requirements is an urgent problem to be solved.
