摘　　要：以常规热平衡方法为基础，将等效热降法应用于电站热力系统汽水流量的分配计算，计算结果与常规热平衡方法完全相同，并可简捷快速地计算出热力系统连接方式及局部参数变化对汽水流量分配的影响，为电站热力系统应用热力学第二定律进行定量分析奠定了基础。In this paper the authors apply equivalent heat drop method to the steam - water flow distribution calculation of a power Plant thermodynamic system, based on the normal energy balance method. The calculation result by those method is identical completely. The deciding quantity calculation can be fast made specially because of the thermodynamic system link mode and local parameters change, and foundation for the deciding quantity analyses by thermodynamic second law is establishaed.
