火力发电系统是复杂的能量转化系统，包括众多的子系统和热力设备，局部的计算与分析无法对系统整体情况进行全面评价，而系统整体多参数、强耦合、非线性等特点为全面计算及定量分析等工作增加了困难。运用过程系统工程的理论及模拟方法，以某200 MW热电联产机组热力系统为研究对象，对多循环嵌套的复杂系统进行模拟研究。结果表明，在建模前使用合理的系统结构分析方法可有效提高大型复杂系统的计算效率和模拟精度，通过系统模型的构建与模拟计算，对系统整体综合状态评估以及系统局部关键参数的判断与预测都具有重要作用。

Thermal power system is a complex energy conversion systems,Including many subsystems and ther-mal equipment,calculation and analysis of the local system Inability to make comprehensive evaluation on the system overall,and the system as a whole with characteristics of more parameters,strong coupling and nonlin-earity for comprehensive calculation and quantitative analysis increased difficulty. This paper uses the method of process system engineering theory and simulation,taking a 200 MW cogeneration unit thermodynamic system as the research object,simulation study more than a nested loop simulation of complex system. The results show that before modeling reasonable system structure analysis method can effectively improve the computation effi-ciency of large complex system and simulation precision,through the building system model and simulation cal-culation,the comprehensive state evaluation system as a whole and some key parameters of judgment and pre-diction system plays an important role.
