Abstract

The invention relates to a nuclear power station DCS debugging system and a method thereof. The system comprises: a computer server, an operation terminal and a test dolly which are connected through network communication. The operation terminal is used to receive initial condition input by a user and debugging operation information and display an operation simulation result of the computer server so as to be used for DCS debugging analysis. The computer server simulates a continuous production process of the nuclear power station according to the initial condition and the debugging operation information so as to generate dynamic test data. The test data is sent to DCS equipment through the test dolly. A DCS control instruction from the DCS equipment is received and the test data is recalculated. By using the system and the method of the invention, logic preview before nuclear power units are started can be realized so as to reduce a nuclear power unit debugging and starting risk, shorten debugging construction time and save project construction costs.

Description

technical field [0001] The invention relates to the technical field of nuclear power, more specifically, to a DCS debugging system and method for a nuclear power plant. Background technique [0002] At present, all new nuclear power units in the world have adopted advanced main control room design and fully applied digital instrument control system (DCS for short) to realize centralized monitoring, flexible operation, control and protection functions of the process system of the whole plant. The nuclear power plant DCS integrated monitoring process system is huge, with a large number of various process equipment, and some control and protection logic functions have special requirements for safety. The application software design function verification and on-site commissioning progress are often related to the overall situation, which can directly affect the commissioning and start-up of the unit Experiment with safety and deadlines. [0003] At the present stage, the design...
