摘　　要：分布式光伏发电项目中高、低压电缆仍较多采用铜芯材质电缆,铝合金电缆使用的场合极少。电缆部分的成本虽占比整个光伏系统投资成本约2%~3%,占比相对较小,但受531号政策文件的影响,电价补贴不断下调。光伏企业利润必将受到波及,再加上行业竞争日益激烈,进入微利时代,须站在项目全方位角度加速系统成本下降,才能满足行业对光伏发电平价上网的要求(向脱硫燃煤机组上网电价看齐)。文章结合实际案例,分析在技术可行基础上铝合金低压电缆替代铜芯电缆的经济优势,为后续降本增效、方案优化提供参考依据。High and low voltage cables in distributed photovoltaic power generation projects are still mostly copper core cables, while aluminum alloy cables are rarely used. The cost of cables accounts for about 2%-3% of the investment cost of the entire photovoltaic system. The proportion is relatively small. However, under the influence of policy document No. 531, the electricity price subsidy has been continuously reduced. The profits of photovoltaic enterprises will be affected. In addition, the industry competition is increasingly fierce, and the industry has entered the era of meager profits. Photovoltaic enterprises must accelerate the system cost reduction from an all-round perspective of the project, so as to meet the industry’s requirements for parity grid connection of photovoltaic power generation(similar to the grid connection price of desulfurization coal-fired units). Based on practical cases, this paper analyzes the economic advantages of replacing copper core cables with aluminum alloy low-voltage cables on the basis of technical feasibility,and provides a reference for subsequent cost reduction and efficiency increase and scheme optimization.
