This article presents the estimation of the electrical parameters of a three-phase transmission line from measurements of transient voltages in a laboratory-scale model using non-linear optimization methods. The aim of the study is to be able to determine the parameters more accurately and faster compared to conventional methods. The conventional tests open circuit and short circuit were conducted on a scale model in the Laboratory of Electrical Machines at the National Polytechnic School. The parameters derived from these tests constitute the initial electrical parameters of the model. Subsequently, a transient voltage event is simulated by energizing the line by means of a switch that provides an experimental voltage signal. The signal is captured by a recording instrument for subsequent analysis. With the help of MATLAB-Simulink, the simulation of the transmission line is performed with the respective voltage transient obtained by energizing the line, with a nominal voltage and no load. In the simulation the parameters obtained in the conventional tests, the distributed parameter model of the transmission line and the transient voltage event are used. Finally, the MATLAB-Simulink Parameter Estimation optimization tool is used to tune the transmission line parameters, so the signal of the simulation resembles as close as possible to the experimental response.
