| Abstract | |
The accuracy with which the parameters of a three-phase transmission line are known is directly related to the reliability in the operation of an electrical system. Such parameters are used in the parameterization of relays that guarantee the protection of system components against transient phenomena, such as short circuits, and, besides, the line parameters are used by power flow software that monitoring in real-time the loading of system components. In this work, techniques for estimating the parameters of a transmission line are studied based on measurements made at the sender and receiver terminals of the line. For this purpose, a methodology of noise modeling in the measurements was developed that considers the particularities of each proposed equation. Thus, for each modeling, a solution was proposed, employing different system identification techniques based on the minimization of the mean square error. Finally, it was possible to trace a comparison between each of the solutions proposed in this work and those similar ones already developed in other references. (AU) | |
