Design of foxboro I/A virtual simulation software in nuclear power plant

In order to reduce accidents in nuclear power plant, simulation for operator training and system validation precommission is very important. The application of Foxboro I/A control system in nuclear power plant leads to the development of its virtual simulation software. In this paper, a reasonable structure of its virtual software is established. Real-time server software VCP and human-machine interface VWP form the two parts of the virtual simulation software. The VCP is built by VC6.0++; the VWP page is embedded by ActiveX dynamic OCX and browsed by IE. The Virtual simulation software for Foxboro I/A control system is crucial to security and economy of nuclear power plant in present and in the future.
