摘要：

The detection algorithms depend on the network topology, the neutral grounding of the secondary winding in H.V./M.V. transformers being one of the main factors to consider. In compensated distribution systems, we need complex detection algorithms based on network parameters estimation. The neutral voltage is the most sensitive magnitude to detect an unusual situation but it is not a selective parameter. In this paper we present the new DSTRP that calculates the influence of each feeder asymmetry in neutral voltage. We also analyze the measurement errors influence that limits the sensitivity threshold of this algorithm.
