火电机组分布式控制系统仿真新思路

介绍了在火电机组仿真机的研制过程中根据INFI-90控制系统的模型自动转换为STAR-90 仿真控制模型,并对INFI-90操作员站的文本化画面进行翻译驱动,能大大缩短仿真机的开发周期和提高仿真度,不仅使仿真机与实际机组具有完全一致的内部控制逻辑,而且使仿真机与实际机组具有完全一致的操作员站的画面显示、操作风格等,大大减轻了仿真机开发人员的工作量,体现了该方法良好的应用前景,为火电机组分布式控制系统(DCS)仿真提供了一条新思路。

A New Idea for the DCS Simulation of the Thermal Power Generating Units

In an investigation on the simulation machine of thermal power generating units, the development period of the simulation machine can be greatly shortened and the fidelity improved by transforming the INFI-90 control system model into a STAR-90 simulation model and adopting the automatic translation technology in the text formed pictures of INFI-90 operator station. Meanwhile, the simulation machine is made to have not only a completely conformable inside control logic as that of the actual units, but also a completely conformable display of the operating styles at the operator' s station as that of the actual units. By greatly reducing the workload of simulation machine development, the method has favorable application prospects and offers a new idea for the simulation of the distributed control system (DCS) of thermal power generating units.
