Redesign of power supply for wind farm meteorological tower
Abstract
El trabajo consiste en el desarrollo del sistema de salida de un sistema de secundario de alimentación para una torre meteorológica. En caso de que el principal falle, un interruptor automático deberá seleccionar entre las diferentes fuentes (principal, solar y batería) de forma automática para asegurar el envío constante de información. Será diseñado, simulado e implementado mediante unos diodos en paralelo que, mediante el voltaje de las diferentes entras, seleccionará la salida con una prioridad predeterminada. La torre necesita tres voltajes de alimentación para los diferentes equipos (24, 12 y 5 V) por lo que será implementado un diseño basado en dos convertidores síncronos en cascada que aseguren la eficacia y seguridad del sistema.
The main purpose of the project is the design of the output subsystem of the backup system of a meteorological tower in Dallas. In case that the main source fails, an automatic transfer switch (ATS) need to select between the three different sources (main power, solar subsystem and main battery) automatically assuring the transfer of data all the time. This switch is going to be designed, simulated and implemented by using three diodes in parallel that, depending on the input voltage of the source, will activate one or another. The MET tower need three different voltages (24, 12 and 5Vdc) for the different devices. A designed based in two synchronous buck converters connected in cascade is designed to assure efficiency and reliability during the use of the backup system.
