摘要
以卡森模型为基础 ,对一段 2km未换位的同杆并架 4回输电线及避雷线的试验线路 ,用Matlab仿真计算了序参数及线路不平衡度。根据序参数计算结果研究了实际线路参数对各类不平衡系数的影响规律及特性 ,其主要影响因素有导线相序排列方式、导线对地高度、导线间距离以及导线自身属性等。分析结果表明 。
Sequence parameters and unbalance level in parallel untransposed 4-circuit transmission lines and lightning shielding line with length of 2 km is calculated on basis of Carson model. The particular influences of actual parameters of the lines on different unbalanced coefficients are analyzed by the calculated results. The main influencing parameters are as following: the phase arrangement of the lines, the heights of lines from earth, the clearance among the lines, and properties of the lines, etc. The analysis shows that the triangle pole is better than perpendicular and level poles on account of the unbalance level.
