摘要
在确定凝汽机组背压变化引起的机组功率变化时，以汽轮机变工况为基础并考虑热力系统工况的变化，计算在不同负荷及热力系统不同的条件下，机组背压变化所引起的功率变化。并提出一种简化的计算方法，以便于经济运行。
When determining the POwer variation due to the back pressure change of the condensing turbines, the change of the unit capacity is calculatedwhen the steam condition changed or the thermal system is in diferent type, which is studied on the basis of the theory of the tUrbine and thermalsystem Performance in variable steam conditions. When determining the POwer variation due to the back pressure change of the condensing turbinesthe unit capacity change is calculated under various loads on basis of the theory of the turbine and thermal system Performance in varied steam con-ditions, with consideration of Performance variation of thermal system. A sample method is established for the economic performance of the unit.
