<p>In a co-generated power supply system for performing co-generated power supply to a load (Lac/dc) by the use of a wind turbine generator (WTG), a solar cell (PV) and a fuel cell (FC), a storage battery (B) and a commercial AC power source (Utility), the wind turbine generator (WTG), the solar cell (PV) and the fuel cell (FC) whose rated voltages are made equal to a rated voltage of the storage battery (B) are used as DC power sources; AC power from the commercial AC power source (Utility) is supplied to the load (Lac/dc) until the storage battery (B) is fully charged by the DC power sources; DC power from the storage battery (B) is supplied to the load (Lac/dc) when the storage battery (B) has been fully charged; and the AC power from the commercial AC power source (Utility) is supplied to the load (Lac/dc) as the storage battery (B) approaches the terminal period of discharging. Thus, there can be provided the novel co-generated power supply system, in which the electric power of the natural energy system having many fluctuation factors is combined with the stable electric power such as the midnight electric power or the fuel cell, so that the stable electric power is supplied to the load via the electronic transformer commonly used at a usage rate of almost 100%, thus reducing the cost and enhancing the performance as the entire system, so as to spread and prevail the co-generated power supply and save the energy.</p> |
