Abstract:
Based on the analysis of digital I&C system TXP/TXS of the large PWR nuclear power plants,this paper takes the safety control system TXS as the simulation object,and designs and develops the DCS virtual machine software VTXS(Virtual TXS) on the platform of Windows,for the application together with the process control system TXP.Adopting the method of object-oriented modeling and modularization program design,using technologies such as multithreading and multiprocess-communication,by the basic way of automatic code analysis and data code translation and with Visual C++ platform as the developing environment,VTXS recreates the functions about safety control of real TXS with high fidelity in the form of software.
