FUEL CELL POWER MANAGEMENT SYSTEM AND ANTI-ISLANDING METHOD THEREOF

摘要

PURPOSE: A fuel cell power management system is provided to prevent the degradation of the quality of electricity outputted from PCS(power conditioning system) and to extend the lifetime of a fuel cell compared with a conventional power control and management system. CONSTITUTION: A fuel cell power management system comprises: a battery(21) generating DC power; a PCS(22) generating AC power from DC power generated by the battery; a power grid connected to the PCS; a detector(26) for detecting the change of AC power flowing into the output beam furnace of PCS; and a control part(27) controlling the connected state between the power grid and PCS according to the detection result at a detector.
