Title:
HEAT STORAGE POWER GENERATION SYSTEM AND POWER GENERATION CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/264451
Kind Code:
A1
Abstract:
[Problem] To provide a heat storage power generation system and a power generation control system with which a heat storage material inside a heat storage unit can be used suitably. [Solution] The heat storage power generation system according to the embodiment is provided with a heating unit for heating a first heat transfer fluid, and a heat storage unit that includes a heat storage material heated by the first heat transfer fluid, and that heats a second heat transfer fluid by means of heat stored in the heat storage material. The system also comprises a power generation unit for using the second heat transfer fluid to generate power, a heating control unit for controlling the heating of the first heat transfer fluid carried out by the heating unit, and a power generation control unit for controlling the power generation carried out by the power generation unit. The heating control unit controls the heating of the first heat transfer fluid on the basis of two or more limit values among a first limit value related to the amount of energy consumed by the heating unit, a second limit value related to the temperature of the first heat transfer fluid, a third limit value related to the internal temperature of the heat storage unit, and a fourth limit value related to the change rate of the internal temperature.
