天然冷源系统在水电企业应用研究

Study of natural cold system in hydropower station application

为研究天然冷源系统在水电企业应用的可行性,在SWOT分析方法的基础上,建立了天然冷源系统节能量与总投资关系的数学模型,得出模型的分析解,并提出了天然冷源节能投资系数(CEIC)的定义,分析了其在不同总节能量及冷源系统总投资条件下的变化规律,基于该模型对溪洛渡水力发电厂地下厂房天然冷源系统进行了特征参数计算及验证。研究表明,天然冷源节能投资系数受总节能量和系统总投资影响,当系数≥1时认为是应用可行的,系数≥2.5认为该系统具有良好的节能效益。

For the feasibility study of natural cold system in hydropower station application,on the basis of SWOT analysis method,a mathematical model of energy saving and total investment in the natural cold system was established and its analysis solution was solved. The definition of natural cold energy saving investment coefficient（ CEIC） was put forward,the natural law in different total energy and total investment under the condition of natural cold system was analyzed. The model was used to calculate characteristic parameter in the nature cold system in Xiluodu underground Power Station and reached its validation. Research shows that the natural cold energy saving investment coefficient is affected by total energy saving and the total investment in the system. When CEIC above 1 is feasible in the application and CEIC above 2. 5 has a good energy saving benefits.
