Diseño de la Parte Activa de un Transformador de Potencia Mediante Algoritmos Genéticos para la Minimizar las Pérdidas
Resumen
Este trabajo aborda el problema de optimización del diseño de la parte activa de un transformador trifásico de potencia de 10 MVA y 115/ 13.8 kV con núcleo tipo columnas y devanados en disco. El objetivo es determinar un diseño que cumpla con el menor costo total de adquisición considerando los factores de evaluación de pérdidas. Este es un problema frecuente al que se enfrentan los fabricantes de transformadores durante la etapa de licitación donde deben ofrecer en corto tiempo un diseño que minimiza el costo de adquisición, el cual está compuesto por el costo de materiales más el costo monetario de las pérdidas. Es por ello que el problema de optimización está construido por estos dos factores que actúan como fuerzas opuestas. Se reporta el método de Algoritmos Genéticos (AG) para la implementación de la optimización al modelo de la parte activa que calcula dimensiones, masa del núcleo, devanados, pérdidas en el núcleo e impedancia del transformador. Se reportan los resultados mostrando que se encuentran los parámetros del diseño que minimizan la función costo y que cumple con las restricciones especificadas.
