不同天然气调峰方式经济比选研究

Comparison and Selection of Different Modes for Gas Peak Shaving

目前,我国天然气调峰能力严重不足。如何根据实际需要选择最佳调峰方式、实现投资效益的最大化是天然气供应商在建设调峰设施过程中必须解决的问题。针对目前不同调峰方式经济比选存在的问题,在研究不同调峰方式经济特点的基础上,提出了按单位调峰成本年值对不同调峰方式进行经济比选。给出了不同调峰方式单位调峰成本年值的计算方法,及不同调峰方式经济比选应注意的问题。

At present,a serious shortage of gas peak shaving capacity exists in China.The selection of the optimal mode for gas peak shaving according to actual needs and achievement of maximal investment benefit were problems that gas suppliers must solve during the construction of peak shaving facilities.For the problems in the comparison and selection of different modes for peak shaving,the selection method according to the annual value per unit cost of gas for peak shaving was presented on the basis of analyzing economical characteristics of different modes for peak shaving.The calculating methods of the annual value per unit cost of gas for peak shaving for different modes were described,and problems needing to pay attention to the selection were also put forward.
