摘要
论文以大唐桂冠合山发电有限公司300MW机组石灰石-石膏湿法脱硫系统(WFGD)为研究对象,开发了该系统的实时仿真算法并进行了通用模块化设计,新算法主要包括脱硫塔喷淋区、脱硫塔氧化结晶区、旋流分离器、真空皮带过滤机、湿式球磨机等。运用基于图元的工程模块化建模方法,建立了湿法脱硫系统动态实时仿真数学模型。完成了仿真XDPS监控系统的组态,仿真PLC湿式球磨机控制画面的设计及组态,仿真就地系统画面的设计及组态。开发完成的300MW机组石灰石-石膏湿法脱硫仿真机在现场运行人员的培训中得到了成功应用。
This thesis focuses on the limestone - gypsum wet desulfurization (WFGD) system of 300MW unit in GUANGXI HESHAN thermal power plant. About this system's real-time emulation algorithm and the general modular design has been carried out. The new algorithm mainly includes the desulfurizer to spray the area, the desulfurizer oxidation crystallizing field, the eddy separator, the vacuum leather belt purifier, the wet ball mill and so on. Based on engineering modularize method, real-time simulation mathematic model of WFGD was establish. Various work have been carried out including configuration of simulation XDPS monitor system, design and configuration of simulation PLC wet ball mill control pictures, design and configuration of simulation on the spot system pictures. The 300MW unit WFGD simulator has been successfully implemented in operation staff training.
