Accurate fault location is a challenge for most Distribution Management Systems (DMS). This paper analyses one possible method for Fault Location (FLOC) using impedance information available from Impedance Fault Relay (IFR). This method is applicable for symmetrical as well as un-symmetrical networks. It delivers accurate results for radial as well as meshed networks. The Impedance based FLOC is a...
During a fault, protection relays of the faulty line as well as adjacent lines react and record measurement data. The records of an adjacent healthy line can be used for line parameter identification. The special feature of the proposed method is the consideration of unsymmetrical transmission lines and the application of a high-accuracy signal modeling technique. Derived from a π line model, an estimation...
