A new numerical distance relaying algorithm based on Mathematical Morphology and a Least-Square Curve Fitting has been proposed. It makes use of morphological operators to detect and classify the faults and a Curve Fitting method to estimate the fault distance. To show the effectiveness of the proposed technique, computer simulations have been carried out on a test system, considering several fault types in different locations, loading angle and fault incidence angle. Due to simple mathematics operations used, the protection scheme proposed displays secure and effective high speed fault detection and tripping.
