Abstract: The traditional traveling wave location technology uploads all the captured high-frequency and massive traveling wave raw data to the main station without discrimination, which not only imposes a huge bandwidth pressure on the communication but also leads to extremely low positioning efficiency. Once the main station malfunctions or the communication link is interrupted, all the fault location functions will instantly collapse. Therefore, we have conducted research on the edge computing technology of traveling wave head data. By completing the core traveling wave head detection and timestamp marking locally at the edge terminal, we have moved the positioning calculation from the cloud to the site. The terminal directly collaborates with the opposite terminal to calculate the positioning result. The positioning action can be completed locally at the moment of the fault occurrence, enhancing the edge judgment capability of the traveling wave module, reducing the upload of recorded wave data, thereby increasing the speed of the traveling wave distance measurement algorithm, achieving rapid and precise positioning, and conducting functional application verification.
