Title: COMPRESSED AIR ENERGY STORAGE GENERATOR
Abstract:
This compressed air energy storage generator 1 is provided with a motor 13, a compressor 10, an accumulator tank 11, an expander 12, a generator 15, an inverter 14 for a motor, an inverter 16 for a generator, a power supply command receiving unit 31, a discharge command receiving unit 32, and a control device 30. The control device 30 comprises: a power supply determination unit 30a which determines whether or not a power supply command value is less than the minimum charging power; a discharge determination unit 30c which determines whether or not a discharge command value is less than a minimum discharge power; and an input/output adjustment unit 30e which, if the power supply determination unit determines that the power supply command value is less than the minimum charging power or the discharge determination unit determines that the discharge command value is less than the minimum discharge power, controls the inverters 14, 16 and simultaneously drives the motor 13 and the generator 15.
