Traveling wave data processing system and traveling wave data processing method

Abstract

The application belongs to the technical field of measuring electric variables, and particularly relates to a traveling wave data processing system and a traveling wave data processing method. The traveling wave data processing system comprises two traveling wave sensors, two voltage sensors and two control modules. When the control module collects the traveling wave through the corresponding traveling wave sensor, the real-time voltage waveform data is collected through the voltage sensor to compare with the standard voltage waveform data to confirm the fault time point. The real-time voltage waveform data is judged as interference data or the corresponding fault time point is confirmed. The fault position on the power cable is calculated according to the two corresponding fault time points. After the traveling wave is sensed, the real-time voltage waveform data is compared with the standard voltage waveform data to confirm or correct the fault time point. In the case that the traveling wave cannot be sensed, the fault time point can also be found out. The special case that the interference between the power cables is excluded can be confirmed, and the fault position on the power cable can be efficiently and accurately identified.
