Logic simulation implementation method, device and equipment for field control object of nuclear power plant

Abstract

The invention discloses a logic simulation implementation method, device and equipment for a nuclear power plant field control object, and the method comprises the steps: obtaining a to-be-tested equipment list according to a field debugging demand; generating a simulation logic page in configuration software, and forming a simulation program in the simulation logic page according to the to-be-tested equipment list; carrying out incremental downloading on the simulation logic page; and executing a simulation program of the simulation logic page according to the simulation requirement so as tocarry out logic function verification on the corresponding to-be-tested local equipment. According to the invention, under the condition that the internal logic of the current configuration software is not changed, the simulation logic page is added to the configuration software of the DCS system platform to simulate the feedback signal of the field device, so that logic function verification canbe carried out under the condition that no field device exists, and the correctness of configuration is verified in advance.

Description

technical field [0001] The invention relates to the field of nuclear power plant debugging, in particular to a logic simulation implementation method, device and equipment for an on-site control object of a nuclear power plant. Background technique [0002] The control objects of the DCS control system of nuclear power plants are a large number of valves and pump sets. The control principle mainly adopts a large sequence control method of one-button start and stop. The sequence control process will involve a large number of valve switches and start and stop of pump sets. [0003] When verifying this part of the sequential control logic function in the DCS control system, since the real action of the field device does not meet the conditions, the feedback signal of the field device can only be forced in the control system. However, it is often unrealistic to carry out sequential control experiments by means of forced feedback signals. The main reason is that this verificatio...

Problems solved by technology

But the site usually does not have such conditions, and if the site has such conditions, it will also affect the commissioning process of the nuclear power plant

[0004] In addition, if the logic test is not performed in advance during the debugging process, the direct trial operation of the system will bring high equipment risks, and a large number of logical configuration changes will waste a lot of water, electricity, gas and other resources
