POWER GENERATION SYSTEM AND POWER GENERATION METHOD

摘要

A power generation system includes a medium circuit through which a medium is circulated; a circulation pump; an evaporator configured to heat the pressurized medium using heat of an external source so as to evaporate the medium, wherein the external source that the heat quantity is capable of fluctuating; an expander configured to be driven using the medium evaporated by the evaporator; a generator configured to be driven using the expander to generate power; and a flow rate control device configured to control the flow rate of the medium flowing into the expander such that, even when the heat quantity of the external source has fluctuated, the number of rotations of the expander or the generator is within a region in which the number of rotations is preset.

1. A power generation system comprising:
a medium circuit through which a medium is circulated; a circulation pump configured to pressurize the medium so as to have the medium circulating through the medium circuit; an evaporator configured to heat the pressurized medium using heat of an external source so as to evaporate the medium, wherein the external source that the heat quantity is capable of fluctuating; an expander configured to be driven using the medium evaporated by the evaporator; a generator configured to be driven using the expander to generate power; and a flow rate control device configured to control the flow rate of the medium flowing into the expander such that, even when the heat quantity of the external source has fluctuated, the number of rotations of the expander or the generator is within a region in which the number of rotations is preset.
