针对目前高压输电线路参数测量方法存在假设线路三相参数对称的问题，提出了在线路三相参数不对称情况下的一种新的测量方法。这种方法基于输电线路参数的不对称性，在单相测试电源下，通过多次测量数据，建立起线路参数的求解方程，从而获得线路参数。这种方法能够反映输电线路的实际情况，不需要正序测试电源，测试方法简单，是一种新的输电线路测量方法。仿真结果验证了本文方法的可靠性。

In view of the present methods for measuring the parameters of high voltage transmission lines, hypothesized that symmetrical the circuit parameters of three-phase, Proposed a new measurement method under asymmetric three-phase parameters .This method is based on the asymmetry of transmission line parameters, establish the equation of solving the circuit parameters through measuring data for many times under the single-phase test power, then gain line parameters. This method can reflect the actual situation of transmission line, don't need positive sequence test power, test method is simple and a new transmission line measurement method .The simulation results verify the reliability of this method .
