Device for identification of power line parameters using synchronous phasors

Installation of measuring devices PMU, which allow synchronous measurements of voltage and current phasors in electrical networks, makes possible to determine the actual values of the electrical parameters of transmission lines. Knowledge of the updated values of the parameters contributes to safer operation of the power supply. For this reason, it was designed the device for identification of the line parameters, which consist of software Estimation of power line parameters in distribution networks using synchronous phasors, server hardware, interfaces, and data storage.
