核电厂虚拟控制系统报警软件设计

Design of Alarm Software for NPP Virtual Control System

通过对核电厂数字化仪控系统Ovation报警功能进行分析,设计专门用于虚拟控制系统的报警软件。软件以虚拟分散处理单元(DPU)运行服务器中控制功能模块运算结果作为报警触发源,利用套接字通信模式实现报警信息的传输,以Active X控件实现报警显示画面的实时交互。该虚拟控制系统报警软件可仿真模拟核电厂Ovation报警系统的主要功能,为核电厂操纵员培训和提高处理故障能力提供有力支持。

Based on the analysis of Ovation alarm function of digital I＆C system in nuclear power plants and the simulation requirements of virtual control system, this paper has designed an alarm software specifically for the virtual control system. This software takes the operation results of control function module in the virtual DPU server as the source of the alarm information, and it applies the socket communication model to realize the transmission of the alarm information, and ActiveX controls have been used for real-time interaction of the alarm display screen. The alarm software can simulate the main features of Ovation alarm system in nuclear power plants, therefore it can provide strong support for training the operators and improving the ability to deal with the fault process in nuclear power plants.
