摘要
本文在对前人工作总结的基础上,从现有的常规热平衡法出发,对凝汽机组回热系统进行数学建模。建立了适合于MATLAB编程计算的凝汽机组主系统、实际热力系统通用矩阵方程,研究了加热器端差、抽汽压损等对机组热经济性的影响。该模型非常适合编程实现和程序分析。采用C语言编制人机操作界面,MATLAB语言编写热经济性计算程序,C语言调用MATLAB程序的方法,建立回热系统的仿真分析系统。最后以一典型600MW机组为分析算例,检验了MATLAB编制的计算程序的正确性和精确度。算例表明:计算软件的操作是可行的,计算结果与常规热平衡法算出的结果是一致的。软件具有通用、智能、精确和适应计算机分析的优点。
On the basis of the work of our predecessors and the existing convertional thermal balance analysis method, this paper proposed a mathematic model for turbine heat recovery system, established generic matrix equation in MATLAB programming for the calculation of the main turbine and the actual thermal system. This model analysis the impact of heater temperature difference and extraction pressure loss to the Heat economy of thermal units, and is suitable for programming and program analysis. Use C language of the man-machine interface, MATLAB languages of the thermal economic calculation procedures, C language calling MATLAB procedures to establish the heat recovery regenerative system simulation analysis system. Finally, use a typical 600MW Unit as an example to test the validity and accuracy of MATLAB program. Example shows that: the operation of the software is feasible and calculated results are consistent with the conventional thermal balance analysis method. The software has the advantage of universal, intelligent, accurate and adapt to computer analysis.
