摘要
分别对35 kV、110 kV、220 kV输电线路采用一般架线方式与张力架线方式的造价进行了比较,测算出各因素对造价的影响;证实张力架线在220 kV及以上输电线路中更具经济优势、一般架线在35 kV及以下输电线路中具有显著经济优势、张力架线和一般架线方式在110 kV输电线路各具经济优势;解决了多参数条件下一般架线与张力架线的优化比选问题,可为输电线路架线决策提供参考。
The paper makes a comparison of the cost of different erection methods,including the common erection method and tension-string erection method,for 35 kV,110 kV and 220 kV transmission lines,and analyzes the influence of various factors on cost.The results indicate that the tension-string erection method is more favourable in cost for the transmission lines of 220 kV and higher voltages,while the common erection method is more favourable for the transmission lines of 35 kV and lower voltages;both methods have their own advantages in cost for the transmission lines of 110 kV.Optimization and comparison of the common and tension-string erection method can thus be carried out more easily with consideration of multiple factors.
