摘　　要：针对汽包炉单元机组协调控制对象的数学模型研究工作中需要解决的现实问题,通过将回热系统纳入机组热平衡进行的数学分析,在汽包炉单元机组全局热平衡的物理概念下,给出一种新型的考虑回热系统影响的汽包炉单元机组实用仿真数学模型。其特点为:物理概念明确;表示方法多样化;模型的具体参数完整并具有客观性;突出受控对象整体的运行机制。同时通过仿真试验进行验证,建立了一个较为客观的控制系统仿真对象,为机炉协调控制系统的评估提供一个方便实用且更加接近客观实际的试验平台和工具。For the practical problems that need to be resolved in research work of the coordination controlled object＇s mathematical model for drum-boiler turbine generator unit, the mathematical analysis was carried out by the regenerator system integrated into heat balance of generator unit. Under the physical concept of the global heat balance of drum-boiler turbine generator unit, a novel type of simulation mathematical model for drum-boiler turbine generator unit with regenerator system was researched, which is characterized by： clear physical concept, describe method is diversified, specific parameters of the model are completive and objective, the overall operating mechanism of the controlled object is highlighted. Mathematical model was verified through the simulation test. Control system simulation object was set up, and the model provides a convenient and practical test platform and tools which closer to the actual objective for assessment of boiler-turbine coordinated control system.
