Implementación de un sistema DIL/METPC con Labview para ensayos a transformadores; Implementation of embedded system DIL/NETPG with Labview for test to transformers

Abstract

Se presentan los resultados de la modernización de las mediciones y el control de la ejecución de ensayos para la determinación de: las pérdidas de vacío y corriente de excitación, las pérdidas con carga e impedancia de cortocircuito y el incremento de temperatura de transformadores de distribución, según la norma IEEE Std. C57.12.90TM-2006. La modernización se sustenta en el diseño y construcción de un sistema de adquisición de datos basado en el DNP/1110 que realiza las tareas de muestreo y control; dirigido por tres programas elaborados en el ambiente Labview. Adicionalmente, se procesan y visualizan los resultados de cada uno de los ensayos. Se implementa un controlador del núcleo de GNU/Linux en conjunto con una aplicación en la zona de usuario, el cual permite obtener una frecuencia de muestreo de 20.22 kHz. La transferencia de información se realiza mediante una conexión por socket TCP/IP.  This paper presents the design and validation for operation of an automatic measurement system for the Laboratory of Distribution Transformers of the CIPEL. The system makes the test for no-load looses and excitement current, load losses and impedance voltage; and temperature rise according to the IEEE Std C57.12.90TM-2006 standard. A data acquisition system based on the DIL/NetPC DNP/1110 manages the sampling and control tasks; lead by three programs written in Labview. The results are processed and shown for each one of the tests. A core controller of GNU/Linux joint to an application in user area allows to obtain a sampling frequency of 20.22 kHz, according to the performance of the system hardware. The transfer of information between the embedded system and the lead programs is accomplished through a connection with socket TCP/IP.
