Diseño e implementación del controlador de carga y descarga de una batería dentro de un sistema autónomo de iluminación pública a partir de fuentes de energía renovable

Abstract

In this document, the design and implementation of a batteries’ charge and discharge controller used for stand-alone street lighting system based on renewable energy (wind and solar) is presented. The electrical magnitudes in batteries and luminary are controlled trough DC/DC power converters and PI controllers, which are digitally executed by a microprocessor. Managing of renewable energy generated is intended by the controller, also batteries’ inlet and outlet current control is accomplished in order to avoid undercharge and overcharge states. Additionally, monitoring system is developed, which is able to record important data related to the whole system’s operation in accordance to get further analysis and fault diagnostics.
