SOLAR PHOTOVOLTAIC POWER GENERATOR

摘要

PURPOSE: A photovoltaic power generation system capable of remotely monitoring photovoltaic module is provided to prevent failure in a monitoring function although some part of relays are out of order by implementing a plurality of replays into a mesh topology. CONSTITUTION: A ZigBee module(1110) is integrally installed with a photovoltaic array corresponding to a photovoltaic module included in a photovoltaic array in one side of a photovoltaic array. The ZigBee module senses output voltage of the photovoltaic module. A relay(1120) is integrally installed with the photovoltaic array in one side of the photovoltaic module and receives output voltage of the photovoltaic module from the ZigBee module. A central management unit receives output voltage of the photovoltaic module from the relay and performs diagnosis on the photovoltaic module using the received output voltage of the photovoltaic module.
