摘要
在仿真机中使用虚拟分散处理单元可实现电厂分散控制系统(DCS)中控制策略的全仿真,对操作员培训和DCS控制策略调试具有重要意义。本文开发的DCOSE仿真支撑系统,使用COM+、共享内存等技术定义了通用虚拟分散处理单元接口,实现了日立H5000系统和西屋WDPF控制系统的虚拟分散处理单元。通过TCP/IP组播及对分散控制系统操作员站、工程师站数据格式的研究,可进一步将虚拟分散处理单元与控制系统的其他部件连接,实现完整的控制系统仿真。
The use of virtual distributed processing unit(DPU)in the plant simulator can implement the whole range simulation of control strategy in DCS, it is of significance for the training of plant operators and the debugging of DCS control strategy. The DCOSE simulation supporting system developed in this paper, using COM+, internal memory-sharing etc. technologies to define the universal virtual DPU interface, realizes the virtual DPUs of HITACHI H5000 system and Westinghouse WDPF control system. Through the study on TCP/IP configuration and the data formats of operator station, engineer station of DCS , the virtual DPU and the other components of control system can be further connected, with the whole simulation of control system realized.
