| 摘要 |
The invention concerns land or marine based gas turbine plants with a multi spool gas turbine arrangement for generating electrical power to supply a load. The invention comprises at least three spools. Each of the at least three spools 10a-10c comprises a shaft 11a-11c and a turbine T1-T3. One of the at least three spools is a high pressure spool and further comprises a compressor C1 mounted thereon. The high pressure spool further comprises a combustor Comb1 operable to combust gas exiting the high pressure compressor to be expanded in the high pressure turbine. The three spools are in fluid communication with each other. The invention further comprises electrical generators G1-G3 mounted on each of the shaft in the at least three spools, the output power of the generators being independently controllable. A heat exchanger 14 may be provided that provides a heat exchange relationship between the gas exiting the high pressure compressor and the exhaust gas of the final turbine T3 in the arrangement. |
