摘　　要：为实现火电机组节能降耗的目的,主蒸汽压力参数对机组经济性能有着十分重要影响。统一物理模型的形式规范简明,数学模型形式简单统一、物理意义明确,能够适用于各种形式的火电机组。在统一物理模型下研究主蒸汽压力的变化对机组的煤耗的影响,推导出主蒸汽压力变化对机组煤耗的影响的物理模型,为火电厂调峰运行起着一定的指导作用。On the purposes of achieving thermal power energy saving, the main steam pressure parameter on the unit has very important influence economic performance. The form of unified physical model specification simple, unified mathematical model is simple in form, clear physical meaning, can be applied to various forms of thermal power units. Under the Unified Physical Model to study the main steam pressure parameters on the unit of analysis of coal consumption, derive the main steam pressure change on the unit coal consumption of the physical model, play a guiding role for the peaking power plant in operation.
