高压输电线路不平衡度影响因素分析

Analysis of Unbalaned Degree Factors of High-voltage Transmission Line

不平衡度是电能质量的重要指标之一.对高压输电线路不平衡度的影响因素,如线路长度、电压等级、杆塔因素、线路导线分裂数、避雷线,以及系统相角等进行了研究,利用ATP和MATLAB工具进行了仿真和计算,提出了一些减少不平衡度的方法.

The unbalanced degree is an important index of power quality.The impacts of unbalanced degree of high voltage transmission line such as line length,voltage level,tower elements,the split number of wire lines,grounding wire,the system phase angle,and other facts are studied,a number of useful conclusions by ATP and MATLAB are identified,and some methods are put forward to reduce unbalanced degree.
