Eco-friendly power supply system for Moveable-weir utilizing renewable energy

摘要

The present invention relates to an eco-friendly movable beam power supply apparatus utilizing renewable energy. The movable beam power supply apparatus includes: a commercial power supply means; a secondary power supply means; and a switching means electrically connecting one of the commercial power supply means and the secondary power supply means to a movable beam. The secondary power supply means includes: a solar module generating power by using the sunlight; a lithium ion battery connected to the solar module and charged with electric power produced by the solar module; and a power conversion system (PCS) converting the power received from the lithium ion battery to power in a constant voltage constant frequency (CVCF) form to output the converted power. The switching means can select one of the output of the PCS and the output of the commercial power supply means to supply power to the movable beam.
