Abstract:

The uncertainty of traveling wave velocity brought the fault location measure error. In order to eliinate the influence of wave velocity, a two-terminal traveling wave fault location method for transmission lines based on overdetermined equation was proposed. This method first needed measure the arriving time of three waves, which were the travelling wave from the fault location to two terminals of the transmission lines, and the two refection waves between the opposite bus and the measure bus. Then with the parameters of the time and lines length, the overdetermined equations were constructed, whose solution could eliminate the uncertainty of traveling wave velocity. The simulation results showed that this method could effectively eliminate the influence of wave velocity, fault distance and ground resistance, and meanwhile show higher location precision and reliability in comparison with other traditional methods.

Key words: traveling wave, fault location, wavelet transform, wave velocity, overdetermined equations
