COMPRESSED AIR STORAGE POWER GENERATOR
Document Type and Number:
Japanese Patent JP2018184906
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To change a rotational speed of a compressor or expander to improve operation efficiency, in a compressed air storage power generator including a plurality of compressors or expanders.SOLUTION: A CAES power generator 1 includes a plurality of motors 13, a plurality of compressors 10, a pressure accumulation tank 11, an expander 12, a dynamo 15, an inverter 14 for electric motor configured to change a rotational speed of a motor, a power supply instruction receiving part 31 configured to receive input power as a power supply instruction value before the input power is supplied, and a controller 30. The controller 30 has a unit 30a for calculating the number of motors to be compressed, configured to calculate, based on the power supply instruction value, a maximum number of motors 13 capable of being rated-driven, and a compression drive control unit 30b configured to rated-drive the maximum number of motors 13 calculated by the unit 30a for calculating the number of motors to be compressed.SELECTED DRAWING: Figure 1
