摘　　要：平行输电线路电气参数是输电线路各项研究的基本数据,平行线路由2回或多回线路构成,由于回数增加,各参数求取比单回线路复杂。此外,由于其各矩阵参数不解耦等特点,需给出适用于不同计算需要的平行线路序参数。针对3种典型杆塔,使用EMTP软件详细计算了500 kV典型杆塔的原始参数和适用于不同计算需要的原始序参数和简化序参数,分析了平行线路各自身属性对的线路参数的影响。Electrical parameters for parallel transmission lines are the basic data for the study of transmission line.The parallel line is constituted by two or more lines and the increasing number of lines makes the calculation of the parameters more difficult than the single-circuit transmission.In addition,since its matrix argument can not be decoupled,it is necessary to offer different order parameters for the different calculation needs.Considering the three kinds of typical towers,this paper adopts EMTP software to make a careful calculation of the original parameters for 500 kV typical tower,as well as the original and simplified order parameters for different computing needs.The influence on the line parameters by the respective attribute of the parallel transmission lines is also analyzed.
