Title:
POWER GENERATION SYSTEM AND ELECTRIC POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/012845
Kind Code:
A1
Abstract:
A power generation system provided with: at least one power generation device (3), which generates electric power in accordance with rotation of an input shaft (31); and a power storage circuit (12), which includes at least one capacitor (C1-C4) for storing the energy of the electric power generated by the power generation device (3). The power storage circuit (12) has a capacitance equal to or in the vicinity of an energy maximization capacitance representing, in energy-capacitance characteristics calculated as the upper limit energy that can be accumulated in the power storage circuit (12) with respect to the capacitance of the power storage circuit (12), the capacitance at which the upper limit energy is maximized. The energy-capacitance characteristics are calculated on the basis of the capacitance of the power storage circuit (12), the electromotive force of the power generation device (3), the internal resistance of the power generation device (3), and the duration of a single power generation operation by the power generation device (3).
