摘要
主要聚焦于解决大型集中式逆变器型光伏电场电力电缆长度在工程投资决策阶段的计算难点,即在项目投资估算期,在已知项目容量、设备数量和地块面积,而设备布置和选型相对模糊的情况下,通过多元线性回归模型,高效准确地预估项目所需的电缆长度,为大型光伏电场项目的投资估算和电缆长度造价提供依据。
This study primarily aims to address the calculation challenges of the power cable length of large centralized inverter-type photovoltaic electric fields in the project investment decision-making stage,that is,during the project investment estimation period,when the project capacity,equipment quantity and land area are known,and the equipment layout and selection are relatively vague,the cable length required for the project is efficiently and accurately estimated through the multiple linear regression model,providing a basis for investment estimation and cable length cost of large-scale photovoltaic electric field projects.
