摘要

介绍、分析了基于全球定位系统（GPS）技术的输电线路互感参数带电测量系统;提出现有的谐波测量仪增加接收GPS同步信号等功能，亦可用于线路互感参数测量;分析了测量原理和理论依据。结合辽宁王南Ⅰ，Ⅱ回线路改造后，与其相平行的多回500 kV线路参数测量具体项目，介绍了多回平行线路互感参数带电测量方法;针对该测量方法现场实施中的难点，提出了2种新的实施方法。给出了测量结果;并采用其他测量方法对部分测量结果进行了测试对比，从而间接验证了测量结果的正确性。结果表明，文中介绍的测量方法可满足工程需要。

Abstract

The live line measurement system of transmission lines with mutual inductance based on GPS is presented and analyzed. It points out that the harmonics' analyzing apparatus can also be used to measure the parameters of lines with mutual inductance if the function of accepting GPS signals is added. The principle and theoretical background are demonstrated. The proposed live measurement method for several parallel lines with mutual inductance is implemented on the project of parameters' live measurement of several 500 kV lines， which are parallel with the rebuilt Wang-NanⅠandⅡ lines in Liaoning Province. To deal with the difficulties， two new implementary methods are proposed.By these methods， the measuring results are obtained. By comparing with some results from other measuring methods， the validity of the results is proved indirectly. The results indicate that the measuring methods presented can meet the requirement of real projects.
