Design and Verification of Virtualization Transplantation Method for Distributed Control System

分布式控制系统(DCS)虚拟化移植的技术路线包括纯模拟、虚拟实物模拟、实物模拟等.基于虚拟实物式技术路线,提出了DCS架构虚拟化移植和现场控制站虚拟化移植的技术方案,分析了实物系统与基于虚拟DCS技术路线的虚拟化系统架构上的异同,优化了通信机制,以提高虚拟DCS的拟真性.同时,以某核电厂堆型调节系统为例,比较了实物DCS与虚拟DCS在相关应用功能下的实验结果,相关参数记录曲线的变化趋势基本一致,证明该虚拟化移植的技术路线可应用于实际工程.

Virtualization transplantation technologies of distributed control system(DCS)include simulation,emulation and stimulation.Based on emulation,a set of technology solution for virtualization transplantation of DCS architecture and field control station was proposed.Similarities and differences between the actual control system and virtual DCS based on virtualization system architecture were also analyzed.Therefore,the communication mechanism of the virtualization system was optimized to improve the emulation performance.Moreover,a nuclear reactor power regulation system was taken as an example.By comparing actual control system and emulation system under related application functions,the trend of curve of related parameters is basically the same,and the results proved that the method of virtualization transplantation can be applied to practical projects.
