激励式仿真系统一机多模功能的设计与实现

一机多模功能是提高仿真培训系统利用率的有效方法之一,能大大提高火电机组仿真培训的效率,已经成为火电机组仿真系统设计过程中的必备功能之一。在分析了国内火电机组一机多模仿真系统的基础上,以火电机组激励式仿真系统为对象,阐述了不同体系结构下一机多模功能需求的异同。以自主研发的基于虚拟DCS（分散控制系统）的激励式火电机组仿真支撑系统为依托,构建实时数据库进行多模型数据管理、多仿真任务调度和模型控制等子功能的设计,并在Windows平台中实现了一机多模功能,最后给出了一机三模的仿真系统实例。

Design and realization of the multi-model function in stimulation mode simulation system

The multi-model function was widely used to increase the utilization rate of simulation training system(STS).Based on the function the efficiency of STS in thermal power plant will be greatly improved,so it has become the essential function in thermal power unit training systems.The multi-model simulation system of domestic power plants was introduced.The structures of simulation systems in stimulation mode and traditional mode were analyzed,as well as the similarities and differences of multi-model functions between them.Relying on the stimulation mode simulation support system,which was based on virtual DCS,and was independently researched and developed,the real-time database was constructed.The database was used for the design of some sub-functions such as multi-model data management,simulation task scheduling and model control in the Windows platform.Finally an example of a triple model simulation system was realized.
