Description
Summary:In order to avoid autoreclosure onto permanent faults, a new numerical algorithm for arcing faults detection and fault distance calculation is presented. It provides the results independently from other protective devices, which is an important improvement to the existing methods. The new approach, the mathematical model established in the spectral domain and the solution for the earthless faults are given. For the purpose of unknown fault distance and arc voltage amplitude estimation, the least error squares method is used. The new algorithm is tested through numerous computer simulations and in the laboratory environment.
