摘要
为适应大型锅炉设计和运行优化的需要,以模块化建模系统MMS为平台,建立了国产600MW火电机组亚临界锅炉的动态数学模型.模型从建立到仿真计算全过程,采用MMS软件操作,执行简单、快速,并以此机理为基础,较全面地考虑了发生在锅炉内部的物理化学过程.仿真结果表明该模型动态响应合理,符合机理分析.其阶跃扰动仿真计算结果适用于对现场机组变化的快速分析、指导,亦可对锅炉设计提供性能参考资料.
In order to meet the demand of large scale boiler design and operating optimization, this paper establishes the dynamic mathematic model for domestic 600MW subcritical pressure boiler. MMS software is adopted in the whole process from modeling to simulation. This software make process simple and quick. This model is based on modulariza- tion and the comprehensive physical and chemical process in boiler is considered. Simulation result shows that the re- sponses of this model under different disturbance are coincident to mechanics analysis. The simulation result under ste Pdisturbance can be used to analyze unit changes and provide some guide and it also can supply performance reference data to boiler design.
