Title:
COMPRESSED-AIR STORAGE POWER GENERATION METHOD AND COMPRESSED-AIR STORAGE POWER GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2016220350
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compressed-air storage power generation method capable of maintaining high charge/discharge efficiency as a whole even in the case where the quantity of air stored in a pressure accumulation tank is varied from a reference storage value, and enlarging a pressure range of the pressure accumulation tank that can be operated by predetermined rating input or rating output.SOLUTION: The compressed-air storage power generation method includes: in a compressed-air storage power generation device 2, defining a storage value indicating that the quantity of stored air in a pressure accumulation tank 12 is in a predetermined intermediate state, as the reference storage value; performs setting in such a manner that at least one of a motor 32 and a generator 30 is rotated at a rating rotation speed at the reference storage value; controlling at least one of the motor 32 and the generator 30 in such a manner that the motor or the generator is rotated at a rotation speed equal to or lower than the rating rotation speed in the case where a storage value indicating the present quantity of stored air in the pressure accumulation tank 12 is greater than the reference storage value; and controlling at least one of the motor 32 and the generator 30 in such a manner that the motor or the generator is rotated at a rotation speed equal to or higher than the rating rotation speed and equal to or lower than an allowable maximum rotation speed in the case where the storage value indicating the present quantity of stored air in the pressure accumulation tank 12 is smaller than the reference storage value.SELECTED DRAWING: Figure 1
