Abstract

This study proposes an alternative to obtain the electrical parameters in three-phase transformer models by means of records obtained with readings from measuring devices in protection and monitoring systems associated with the electrical transformer. The possible use of this procedure focuses on the estimation of the electrical model in three-phase transformers during their operation and functioning in an electrical system and their response to transient events. This proposal will reduce resources and time use in comparison with existing methodologies, since these usually require the transformer to be out of service for the connection of high-cost specialized equipment, being often necessary to move the transformer to a specialized laboratory. 

Existing works provide complete transformer models for simulation of transient events, these were used as starting data to tune the parameters in MATLAB-SIMULINK. Evaluated the effectiveness and reliability of the study, it will be of great help in the determination of transient electrical parameters in new transformers or with a considerable time of operation, because due to the use of the equipment and the operating conditions, the electrical parameters may vary with respect to their factory records.
