DISASTER/POWER FAILURE COUNTERMEASURE POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve the problem of a conventional power failure countermeasure power supply system incapable of coping with heavy load power demand of a heavy load requiring large output and high capacity because of not supporting various power supply sources.SOLUTION: A disaster/power failure countermeasure power supply system of the invention comprises: a commercial power supply; an auxiliary power supply system utilizing renewable energy; a multi-inverter to which the commercial power supply and auxiliary power supply system are connected; and an engine generator, which can be added further. The auxiliary power supply system includes: a storage battery for storing electric energy; a fuel cell for converting chemical energy to electric energy; and a natural energy utilization power supply for converting natural energy to electric energy. The natural energy utilization power supply includes at least one of a solar cell, a wind power generator, a small scale hydroelectric generator, and a geothermal power generator.
