Embodiment Construction
[0028] The transmission line lightning strike location method proposed by the present invention comprises the following steps:
[0029] (1) Obtain the position P of the tower where the lightning current online monitoring system is installed from the lightning current online monitoring system 1 , lightning strike time t 1 , and the lightning current that hits the tower is shunted by the tower and the transmission line and passes through the lightning current characteristic parameters of the lightning current sensor in the online monitoring system. The lightning current characteristic parameters include the current amplitude I of the lightning current 1 , lightning current waveform, rise time t up1 and the half-wave time t h1 , and from the lightning current waveform, get the number of peaks N 1 ;
[0030] (2) Obtain the monitoring data from the lightning location system, the monitoring data includes the lightning strike time t in the same area at the same time 2 , Lightnin...
