El modelo está basado en los parámetros del circuito equivalente del transformador y el diseño de una carga no lineal, que provoca una distorsión armónica elevada de las corrientes, permitiendo evaluar su influencia en las pérdidas de la máquina. A través de las señales de tensión ycorrientes en los devanados del transformador, su procesamiento y el empleo de la Norma ANSI/IEEE Std. C57.110,es posible determinar las pérdidas enel transformador considerando la influencia de la distorsión armónica. El modelo se construye a partir del espectro de las señales de corriente de la carga no lineal y de los parámetros del circuito aquivalente del transformador. Los resultados de las simulaciones permiten estimar las pérdidas debido a la influencia de los armónicos, así como su influencia en la eficiencia y la cargabilidad del transformador.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In this work, a method for simulation of single-phase transformers using the Simulink/Matlab software is proposed. The model is based on the parameters of the equivalent circuit of the transformer and the design of a non-linear load, which causes a high harmonic distortion of the currents, allowing to evaluate the influence of this phenomenon on the losses of the machine. From the voltage and current signals in the transformer windings, their processing and the use of the ANSI/IEEE Std. C57.110 Standard, it is possible to determine the losses in the transformer considering the influence of the harmonic distortion of the current. The model is built from the spectrum of the current signals of the non-linear load and the parameters of the equivalent circuit of the transformer. The results of the simulations allow estimating the losses due to the influence of harmonics, as well as their influence on the efficiency and capability of the transformer.]]></p></abstract>
