Research on Engineering Simulator for Function Validating of DCS in Nuclear Power Plant

An engineering simulator for the function validating of Distributed Control System in Nuclear Power Plant(NPP) was developed in this paper.In the engineering simulator,the thermal-hydraulics was modeled by Relap5,the main control system of the NPP was modeled by Matlab/Simulink,the database was built by MySQL,and the control panel was developed by the Visual Studio.NET.Data acquisition system was used to realize the real-time communication between the simulator and the real Distributed Control System in the NPP.The validating results show that the simulator can meet the requirements of validating the hardware and logic control system of DCS in NPP.
