Abstract

Transmission lines serve as pivotal equipment within the power system. Conductors, the primary medium for power transmission and distribution, directly influence the construction cost, operational performance, and long-term benefits of transmission line projects. This study first provides a detailed introduction to the life cycle cost of transmission lines. It utilizes linear regression analysis, the grey model, and the autoregressive integrated moving average model to forecast the electricity sales benefit and quantify the carbon reduction benefits of energy-saving conductors through a methodology. Through the life cycle cost model, we found that operating costs, particularly energy loss costs, dominate the total expenses, accounting for 65% to 66.2%. The JLHA3-425 scheme offers the lowest life cycle cost of 22,891.66 k$. Comparing economic indicators like ENPV, EIRR, and DPP confirmed that the JLHA3-425 medium-strength aluminum alloy stranded wire emerged as the most economically viable option among the evaluated schemes, holding substantial promise for fostering economic and environmental sustainability in electrical power transmission.

考虑生命周期成本的节能导体输电线路经济比较分析

输电线路是电力系统中的关键设备。导线作为电力传输和分配的主要媒介，直接影响着输电线路项目的建设成本、运行性能和长期效益。本研究首先详细介绍了输电线路的生命周期成本。它利用线性回归分析、灰色模型和自回归综合移动平均模型预测售电效益，并通过方法量化节能导线的碳减排效益。通过生命周期成本模型，我们发现运营成本，尤其是能源损耗成本在总支出中占主导地位，占 65% 至 66.2%。JLHA3-425 方案的生命周期成本最低，为 22891.66 千美元。对 ENPV、EIRR 和 DPP 等经济指标进行比较后证实，JLHA3-425 中强度铝合金绞线是所评估方案中最经济可行的选择，在促进电力传输的经济和环境可持续性方面大有可为。
