抽水蓄能电站TBM全寿命期经济性分析研究

Life-Cycle Economic Analysis of TBM in Pumped Storage Power Station

本文通过实际案例计算,采用TBM法施工,对整个抽水蓄能投资的影响情况进行对比分析,从全寿命期分析TBM整体效益,综合考虑固定资产投资额增加,工期缩短后对建设期贷款利息的影响,提前发电后对运营期还本付息额的影响情况。以样本工程的投资数据为基础,提出计算模型。

This paper compares and analyzes the impact of the entire pumped storage investment through actual case calculation and TBM method construction,analyzes the overall benefit of TBM from the whole life cycle,comprehensively considers the impact of increased fixed assets investment,shortened construction period on loan interest during the construction period,and the impact of early power generation on the repayment of principal and interest during the operation period.Based on the investment data of the sample project,propose a computational model.
