A fault location criterion for MTDC transmission lines using transient current characteristics
The characteristics of the DC filter are used for the fault locating of MTDC transmission lines. The inevitable one-end protection blind zones are deduced in the distributed parameter model. The fault line section selection is important to MTDC control strategy. We propose a fault location criterion based on complex wavelet transform. The algorithm is successfully tested and the results are compared with those from other algorithms.
