摘要
A Compressed Air Energy Storage (CAES) system 'iccludes a first combustion turbine assembly (42) having a shaft (52) coupled to a motor (54), a compressor (44) and a debladed turbine element (46). A second combustion turbine assembly (68) has a shaft (74) coupled to an electrical generator (80), a turbine (70) and a debladed compressor (72). A first interconnection (58) is from an output of the compressor (44) of the first combustion turbine assembly to an air storage (66). A second interconnection (87) is from the air storage to the turbine (70) of the second combustion turbine assembly for producing power. An expander (88) and an electrical generator (94) are provided. A third interconnection (90) is from the air storage (66) to the expander (88). A source of heat preheats compressed air in the third interconnection. A fourth interconnection (96) is from the expander to the turbine (70).
