Abstract
Provided is a power generation system including a photovoltaic unit arranged in a flight vehicle which provides a wireless communication service to a user terminal in a communication area formed over a ground, an electric storage unit which is connected to the photovoltaic unit and stores electric power generated by the photovoltaic unit, and a power conditioner which converts the electric power generated by the photovoltaic unit. The electric storage unit is connected, for example, in parallel to connection between the photovoltaic unit and the power conditioner, and the electric power stored in the electric storage unit is supplied to the power conditioner.
Claims13
A power generation system comprising:
- a photovoltaic unit arranged in a flight vehicle which provides a wireless communication service to a user terminal in a communication area formed over a ground;
- an electric storage unit which is connected to the photovoltaic unit and stores electric power generated by the photovoltaic unit;
- a power conditioner which converts the electric power generated by the photovoltaic unit;
- and
- a switch control unit which switches a current from the photovoltaic unit to be supplied to the power conditioner or to be supplied to the electric storage unit;
- wherein
- an input and an output of the electric storage unit are connected to a connection line that connects the photovoltaic unit and the power conditioner, such that the electric storage unit is connected in parallel to connection between the photovoltaic unit and the power conditioner, and the electric power stored in the electric storage unit is supplied to the power conditioner;
- and
- the switch control unit switches the current from the photovoltaic unit to be supplied to the power conditioner when a measurement result of a power generation amount by the photovoltaic unit is higher than a predetermined threshold or the current from the photovoltaic unit to be supplied to the electric storage unit when the measurement result is lower than the threshold.
