Abstract:
A space photovoltaic generation system comprising:a plurality of power generation satellites each having: a photoelectric conversion unit for converting sunlight into electric energy; a transmission frequency conversion unit for performing frequency conversion of the electric energy provided by the photoelectric conversion unit to a microwave; a microwave control unit for controlling at least one of the amplitude and the phase of the microwave output by the transmission frequency conversion unit; and a transmitting antenna for radiating the microwave; a power base having: a receiving antenna for receiving the microwave radiated from the plurality of power generation satellites; and a reception frequency conversion unit for performing frequency conversion of the microwave received at the receiving antenna to one of DC and low-frequency commercial power, wherein the plurality of vower generation satellites are placed in space to form a power generation satellite group, wherein a first array antenna having the transmitting antennas of the plurality of power generation satellites in the power generation satellite group as element antennas is formed, and wherein the aperture amplitude distribution of each transmitting antenna of the plurality of power generation satellites is made a tapered distribution.
