Revise the Unit Matrix Algorithm as to Calculate the CHP Thermodynamic System

利用循环函数法的基本思想,在单元矩阵计算模型的基础上根据热电厂的运行特点和特殊工况,将单元矩阵算法应用于热电厂性能计算时的部分结果进行修正,在保证计算结果准确的同时简化了计算过程,并且使模型对不同类型电厂的适用性得到加强,为热电厂的热力系统性能计算和节能分析提供了一种方便、有效的方法。

This paper taking the Cycle Function method as fundamental ideas and the Unit Matrix calculation model as basis to revise the segmental results which draw from the Unit Matrix algorithm when it is used to analyze the performance of a CHP plant. According to the CHP plant operation features, the revised results not only assure the exactitude of the calculation, but also make the calculation process easier. Therefore, the Revised Unit Matrix algorithm could have a wider application, meanwhile, it offer an effective and convenient approach for the analysis the performance and energy conservation of CHP thermodynamic system.
