提出一种基于同步相量测量的输电线路参数在线求解方法。该方法以分布参数线路模型为基础 ,在已知线路两端同步电压和电流的条件下精确求解出线路特性阻抗、传播常数、单位长度电感和电容。仿真结果验证了该方法的正确性。

An on line calculation method of transmission line parameters using synchronized phasor measurement is proposed.Based on the distribution parameter line model,the characteristic impedance,propagation constant,unit length conductance and capacitance of the transmission line are accurately calculated as the synchronized voltages and currents at both ends of the line are known.The simulation results show its correctness.
