Power transmission line pilot protection method and device, electronic equipment and storage medium

The invention discloses a power transmission line pilot protection method and device, electronic equipment and a storage medium. The method comprises the steps of collecting synchronous voltage and synchronous current at protection installation positions on two sides of a line; calculating a voltage fault component and a current fault component on the two sides of the line based on the synchronous voltage and the synchronous current on the two sides of the line; and according to the two-side voltage fault component, the current fault component and the full-length impedance of the power transmission line, determining a fault area. The fault area is judged according to the voltage fault component, the current fault component and the power transmission line impedance, the influence of new energy power supply access to the power grid is avoided, and the sensitivity of power transmission line pilot protection is improved. 本发明公开了一种输电线路纵联保护方法、装置、电子设备及存储介质。方法包括：采集线路两侧保护安装处的同步电压和同步电流；基于线路两侧所述同步电压和同步电流计算线路两侧电压故障分量和电流故障
