本文简单介绍了仿真器的发展、构成及特征。着重论述了所研制的催化裂化装置培训操作人员用的仿真器硬件、软件、数学模型及仿真操作实验。实验证明,本仿真器可以用来培训操作人员,并能表明操作条件改变引起各有关参数的变化情况。该仿真器提供与实际炼油厂控制室相似的操作环境,通过仪表盘的仪表进行各有关培训项目的操作训练。用仿真器培训操作人员是一种行之有效的技术培训方法。 This article briefly introduces the development, composition and characteristics of the emulator. The hardware, software, mathematic model and simulation operation experiment of the simulator used in training FCC unit are emphatically discussed. Experiments show that the simulator can be used to train the operator, and can indicate changes in operating conditions caused by changes in the relevant parameters. The simulator provides a similar operating environment to the actual control room of the refinery and provides training on various training programs through dashboard gauges. Using simulators to train operators is an effective method of technical training.
