NOVELTY - The system comprises solar power generation part that receives sunlight and produces electricity; wind-force electricity generation part which produces electricity as it uses a wind force called an aerodynamic property of a kinetic energy; fuel cell that uses fuel as it produces electricity while it is gradually driven to 50%, 75% and 100%; electricity produced by solar power and wind-force electricity generation part are supplied to load; load power detection unit which detects military power that uses; hybrid controller block and charge controller that charges a battery with an electricity.    USE - Hybrid power supply system used for supplying stable electricity to subordinates.    ADVANTAGE - The system provides electricity i.e. produced to a solar power generation mode and wind power generation mode as it is provided to the subordinate and supplies a stable electricity in loading a fuel cell which is driven in case of supplying enough electricity to the solar power generation mode and the electricity of producing to the wind power generation mode load, and with supplying surplus power to the electric power system in case it has the surplus power that charges a battery and supplies an emergency fuel cell to provide its subordinates. In that way, the solar power generation mode like the wind power generation mode and fuel cell may not cause pollution to environment while enough electricity is supplied to the subordinate. Hence, economic burden can be reduced to the consumer.    DETAILED DESCRIPTION - The system comprises solar power generation part that receives sunlight and produces electricity; wind-force electricity generation part which produces electricity as it uses a wind force called an aerodynamic property of a kinetic energy which the flow of air has; fuel cell that uses fuel as it produces electricity while it is gradually driven to 50%, 75% and 100%; electricity produced by solar power generation part and wind-force electricity generation part are supplied to load and in case there is shortage of electricity in supplying to load 50% of fuel cell, the stand-alone type inverting function and the hybrid controller block which controls 100% of its outputs in surplus power to the electric power system as it supplies the military power to the subordinates that supplies electricity to gradually drives its load to 75% and a100% according to the insufficient electric energy; load power detection unit which detects a military power that uses load; hybrid controller block and charge controller that charge a battery with the electricity i.e. outputted from power switching part.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of hybrid power supply system.
