The analysed method represents a transmission system in the modal domain as three independent propagation modes that are modelled as three single-phase transmission lines using a suitable equivalent. The estimation procedure is carried out in the modal domain, without the explicit modelling of the phase mutual parameters, which means a significant simplification on the calculation process using the least-square solution method. Since the modal parameters are identified, the self- and mutual parameters can be calculated using the same modal transformation matrix during the line decoupling. The method estimation accuracy is evaluated for a range of sampling rate associated with the relays records.391-398engSampling rateParameter estimationLine parametersSynchronized measurementsFault recordsArtigo10.1007/s40313-018-0378-7WOS:000431055300012Acesso abertoWOS000431055300012.pdf
