Abstract

1416238 Gas turbine plant ATOMENERGI AB 30 Jan 1973 4724/73 Headings F1G and F1Q The invention relates to a gas turbine plant in which air is stored under pressure in an underground chamber, air being taken from the chamber at peak-load periods and supplied thereto during non-peak-load periods. The plant comprises a multi-stage air compressor 4 with inter-stage and after-cooling, being driven by an electric motor 5 during non-peak-load periods to supply air under pressure to an underground chamber 1. The chamber 1 is connected to an upper water reservoir 3 by a duct 2 whereby the chamber is pressurized. At peak-load periods air under pressure is taken from the chamber 1 and passed through line 24 to a pre-heater 13 then to a combustion chamber 6, the combustion gases passing through a plurality of turbine stages with inter-stage heating, the turbine driving an electric generator 8. A pump/turbine assembly 40 is disposed in the duct 2, the assembly being driven by an electric motor 55 through clutch 52 during peak-load periods whereby the pressure of the water in the duct and thus the pressure of the air in the chamber 1, is increased compared with the static pressure that would be obtained due to the difference in levels between the water reservoir and the compressed air chamber. During off-peak periods when the air chamber is being charged and water is being discharged from the air chamber 1 through the duct 2 to the water reservoir, the assembly 40 is driven as a water turbine, the turbine driving an electric generator 56 through clutch 53. A flowmeter 23 is disposed in duct 2 and is connected to a shut-off valve 12. The heat removed from the air during compression in the inter-stage and after-coolers 9 is utilized by passing the heated coolant to a user device 31, a heat accumulator 30 being provided in the system. In Fig. 2 the duct 2 is divided into two paths in parallel 21, 22, a pump 10 being provided in one path and a water turbine 11 in the other. The pump 10 is connected through clutch 43 to the gas turbine 15 during peak-load operation, whereas the water turbine 11 is connected through clutch 42 to the compressor 4 or to an electric generator 14 during off-peak operation when water is being forced up through the duct 2 to the reservoir 3.
