电站锅炉仿真平台构建及验证
|
摘要
针对锅炉炉膛内部运行情况实时信息的获取需求,构建了基于计算流体动力学(CFD)技术的炉内物理场仿真平台,并利用集散式控制系统(DCS)中的相关运行参数进行了验证。采用模型视图控制器(MVC)设计架构,建立了具有4个工作层的锅炉仿真平台总体框架,并设计了平台的模型结构和工作流程,最终通过VS2012、Fluent、Tecplot及Mysql等软件的开发功能实现了锅炉仿真平台的构建。DCS历史数据的验证结果表明,该仿真平台具有较好的准确度,能满足锅炉在线预测获取物理场信息的需要。
Aiming at the demand of acquiring real-time information in the boiler furnace when the equipment is operating, a physical field simulation platform based on computational fluid dynamics(CFD)technology was constructed and verified by relevant operating parameters in the distributed control system(DCS). Making the usage of the Model View Controller(MVC) architectural design, a four-working-layer general framework was established and a model structure as well as a workflow for the boiler simulation platform were designed. By the development functions of VS2012, Fluent, Tecplot and Mysql, the boiler simulation platform was built eventually. The result of DCS historical data verification showed that the simulation platform had reasonalble accuracy, which can meet the need of acquiring physical field information for boiler online prediction.
