摘要
特高压交流同塔双回输电线路工程的经济档距,对于杆塔规划的优化和降低工程总投资意义重大。对特高压交流同塔双回线路在理想条件下的经济档距进行了计算,并从气象条件、地形条件、导线型式、对地距离及铁塔材料等方面,对经济档距作了敏感性分析,探讨了不同边界条件下经济档距的变化趋势,为后续特高压交流工程设计提供了参考。
The economical span of UHVAC double-circuit transmission line has great significance to the optimization of tower design and the reduction of project total investment.The economical span of UHVAC double-circuit transmission line is calculated under ideal conditions.Furthermore,its sensitivity is analyzed from climate,terrain,conductor type,ground clearance and tower material et al.The tendency of economical span under various boundary conditions is discussed.The results may provide references for subsequent design of UHVAC double-circuit transmission line.
