基于年费用法的输电电缆选型研究

Study on Transmission Cable Selection Based on Annual Cost Method

摘要:

输电电缆具有不受自然条件影响，利于城市美观，输电安全性高，维护成本小等优点，逐渐成为替代城市架空线路的优选方案。然而，在电缆规划选型时，传统规划仅考虑电缆的初始投资成本，对电缆运行期间通风散热费用的考虑较少。针对这一研究不足，本文研究提出了考虑年均投资运维成本的输电电缆选型方法，对降低电缆工程的综合成本具有重要意义。

Abstract:

Transmission cables, which are not affected by natural conditions and good for urban aesthetics, high transmission safety and low maintenance cost, etc., have gradually become rhe preferred alternative to urban overhead lines. However, traditional planning only considers the initial cost of the cable while selecting cables, less work have taken the cost of ventilation and heat dissipation during the cable operation into account. Aming at this lack of study, the selection method of transmission cable considering the annual investment operation cost is proposed, which is of great significance to reduce the comprehensive cost of cable engineering.
