Abstract
A space photovoltaic power generation system including a plurality of power satellites arranged in space, each of which converts electrical energy, into which sunlight has been photoelectric-converted, into a microwave, and transmits the microwave to an electric power base. The system can thus transmit a microwave of high power to the electric power base. As each of the plurality of power satellites changes its attitude in space, and its relative location therefore changes, each of the plurality of power satellites can adjust an amount of phase adjustment to be made to the microwave which each of the plurality of power satellites will transmit. A control satellite measures the location of each of the plurality of power satellites for the phase adjustment, and calculates the amount of phase adjustment for each of the plurality of power satellites. The control satellite then transmits the amount of phase adjustment to each of the plurality of power satellites.
