摘要
本文研究探讨燃气-蒸汽联合循环系统建模中增强模型精细性的问题,并总结了相关的途径与方法。首先,借助理论分析和试验数据拟合相结合的方法建立联合循环系统中主要部件全工况特性的通用精细模型;然后,寻找主要因素变化对性能影响的精细修正公式来进一步提高有关部件模型的精度;最后,应用严格的部件间联接方程来进行系统建模时的精细联接。大量实例应用研究验证了建立的联合循环系统模型中增强精细性措施的有效性。
The paper studies and discusses the issues of how to enhance the preeicion of combined cycle model, summarizes the correlative methods. Firstly, AU-operating-condition and universal models of main components is set up by means of combined methods of theoretical analysis and examination data. Then, the precision of concerned component models is enhanced by being inset exact corrected formulas of the primary factors＇ change infuence to peffomance. Finally, the precise connection is put up by using strictly component connection equations. The validity of these methods have been well verified through using in mass example systems analysis.
