Control de voltaje en sistemas eléctricos de potencia usando transformadores con taps.

Abstract

For a normal operation of an electric power system it is required to analyze and control different electrical variables being one of the most relevant the voltage in the nodes of the power system, in this sense an inadequate monitoring and voltage control of the power system could lead to a collapse of the power system something that has already happen in various countries and at a wide-world level. Therefore, this paper focuses on performing of voltage control by using the taps of the power transformers. For this purpose, a mathematical model of the modified Newton-Raphson method has been developed, which allows considering the effect of the taps on the transformers and their involvement in the control of the voltage in the bars of the system, which is simulated in Matlab. In order to validate the proposed modeling, it is applied to the IEEEE system of 14 buses subject to different operating conditions, thus allowing to establish the conclusive aspects in relation to the contribution of the conservation of acceptable voltage levels resulting from the representation of the taps of power transformers.
