| 摘 要： | 为了对四相输电系统的经济性进行评估,以一条实际建设的500 kV紧凑型输电工程作为参照,对四相输电线路进行了模拟的简化设计和造价估算。在此基础上,讨论了单位电能输送成本与输电距离之间的关系,并通过对比三相与四相线路输送单位容量电能的造价对四相输电的经济性进行评估。研究表明,四相输电系统在经济上完全可行,具有良好的应用前景。

| Abstract: | For calculating the costs of four-phase power transmission system,this paper set a 500 kV constrained three-phase power transmission project as a model and made simulated design and costs evaluation of four-phase power transmission system.And based on the design and evaluation data,this paper also discusses the relationship between the power transmission costs and the power transmission distance.It concludes through the comparison of costs between three-phase and four-phase power transmission system that the four-phase power transmission system can reduce costs and has great application prospect. |
