摘　　要：为研究强不对称的单回线路和强电耦合的双回同塔线路正、负序之间的耦合能否忽视及其影响,针对实际线路情况,提出2种基于全球卫星定位系统(GPS)的互感线路序参数带电测量方法:代数法和微分法,并给出了详细的数学模型。采用这2种方法对中山电网220kV互感线路序参数进行带电测量,实测结果与计算结果均表明,该线路存在不平衡现象,应给予重视。In order to study the influence of mutual inductance between negative ＆ zero sequence at the single-circuit transmission line with strong asymmetry and the double-circuit transmission lines with strong magnetoelectric coupling, two live line sequence parameters measurement methods of mutual inductance transmission Line based on GPS： algebra method and differential method are proposed, and the detailed mathematic model is given. These proposed methods are applied in a 220 kV mutual inductance transmission line in Zhongshan power grid. The measurement and the calculation results show that the line has asymmetric problem and should be paid attention to.
