Abstract

The invention relates to a system and a method for automatically testing and verifying a DCS (Distributed Control System) of a nuclear power station. The system comprises a testing unit, a full-process system process simulation unit and a DCS unit to be tested, the test unit sends test data input by a user to the whole-process system process simulation unit, performs analysis according to a returned test result and outputs an analysis result; the whole process system process simulation unit performs simulation processing according to the test data, outputs simulation data to the DCS unit to be tested, performs whole process system process simulation according to a returned simulation instruction, and outputs a test result after simulation is completed; and the to-be-tested DCS unit tests and verifies transient functions of the DCS control systems, interfaces among different DCS control systems or a DCS regulation control system according to the simulation data, and outputs a simulation instruction. Errors or faults can be predicted in advance, the automation degree is high, the testing efficiency is high, and the later risk of the nuclear power unit is reduced.

Description

technical field [0001] The invention relates to the technical field of DCS control systems of nuclear power plants, and more specifically relates to a system and method for automatically testing and verifying DCS control systems of nuclear power plants. Background technique [0002] At present, in the method and system for testing and verifying digital instrumentation and control systems (DCS) of nuclear power plants using digital simulation technology, the interface between DCS control systems produced by different manufacturers of nuclear power plants has not been tested, resulting in when one party's software is upgraded or the communication address is changed. The other party does not predict the interface error, which affects the normal operation of the unit. In addition, the existing test system is too simplified for the debugging test verification simulation process of the DCS control system, and does not cover the entire plant process of the nuclear power plant, resu...
