Abstract: Due to the lack of enterprise-level simulation platform of process industries in current universities and institutes，the enterprise-level process simulation technology is studied，together with virtual reality technology and information interaction technology in this paper. Then through integrating these technologies，a visual and flexible virtual factory platform is developed. Taking a practical refining enterprise as a prototype，a whole development process of a virtual oil refinery on the platform is introduced in detail. Application result analysis shows that this platform provides a good experimental tool for integrating automation teaching and research with accuracy，low costs，strong visual instruction，high extensibility and compositionality.

摘要： 针对目前高校和科研院所的实验室普遍缺乏面向流程工业全企业实验对象，探讨了基于单元模拟的全企业流程仿真实现技术，基于虚拟现实的三维场景实现技术以及流程仿真、三维场景和上层综合应用之间的信息交互技术，给出了兼具直观性和灵活性的虚拟工厂实现方案。并以某一实际炼化企业为背景，具体介绍了虚拟炼油厂的开发过程并对其应用进行了分析。这为综合自动化课程教学和相关研究提供了高精度、低成本的实验研究对象，且具有高展示性、扩展性和组合性等优点。
