Abstract
The real-time monitoring and fault location technology for long distance HVDC overhead transmission or HVDC underground transmission including land and submarine is described in this paper. This technology used a complementary dual-mode detection method, and the results could be re-confirmed by the measured signals stored in the database. In addition, the accuracy is improved by applying a special noise cancellation algorithm using wavelet transformation. Real application cases are also introduced in the paper.
