摘要：
Based on GPS technology, a new Algebra Equation Method (AEM) of live line measuring the parameters of transmission lines with mutual inductance is proposed. The mathematical model of the new method is explained in detail. The hardware structure of the live line measuring system based on GPS is given. Digital simulation results are shown. Finally, an example of live line measuring six 500-kV transmission lines with mutual inductances in North-East China power grid is given. Comparison of results between AEM and an Increment Equation Method (IEM) is also shown. The field measurement results prove that the new method can meet the need of live line measurement of transmission lines' inductance parameters.
