Abstract
This paper focuses on the selection and design of 35 kV cables in the practical application process of large-scale PV power stations.Firstly,compares and analyzes the application of copper cables,aluminum cables,and aluminum alloy cables in PV power stations,and proposes selection principles for 35 kV cables to reduce the construction cost of PV power stations.Then,combining the design practice of actual projects,it comprehensively considers influence factors such as the ambient temperature,soil thermal resistance coefficient,and calculates the minimum allowable cross-section of the cable conductor according to short-circuit thermal stability conditions,to conduct a detailed discussion and verification on the selection of 35 kV cables in the field of large-scale PV power stations.This design can reduce cable investment,lower operational losses of PV power stations,and further improve project profitability,which has practical and feasible significant importance.关键词
