摘要
利用EXCEL软件循环引用功能实现了热力计算中主给水流量、低压缸膨胀终点焓、系统修正后再热蒸汽焓的迭代计算,克服了EXCEL自带工具"单变量求解"所带来的弊端,提高了EXCEL热力计算程序的自动化程度;利用EXCEL进行热力计算编程,便于普通技术人员更快地理解和掌握汽轮机热力计算。
The EXCEL circular reference function is adopted to carry out the thermal iterative calculations of the feed-water flow,low-pressure cylinder expansion terminal enthalpy and the modified system reheat steam enthalpy.The single drawback of EXCEL variable solution has been overcome,and the automation degree of thermal calculation is enhanced.By thermodynamic calculation programming using EXCEL,the technicians can be trained to understand and master the thermal calculation of steam turbine more quickly.
