【摘要】 阐述了电力市场环境下基于热经济性最佳的凝汽器最佳真空传统定义在实际应用中存在的局限性,提出了基于最大赢利的凝汽器最佳真空新定义。分析了两种最佳真空定义的相互关系。以某公司2台300MW汽轮发电机组为例,说明了新定义在发电运营实践中的具体应用方法。更多还原

【Abstract】 The limitations existing in application of the traditional definition for optimal vacuum in condensers based on thermal eco- nomic efficiency in environment of electric power market have been expounded,a new definition of optimal vacuum in condensers based on maximum profit being put forward,the mutual relation between two definitions of optimal vacuum being analysed.Taking 2×300 MW turbo-generator sets as example,the concrete applying method of the new definition in practice of power-generating operation has been explained.更多还原
