Abstract
The invention concerns land-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 (-) comprises a shaft (-), a compressor (C-C) and a turbine (T-T). Each one of the shafts (-) of the at least three spools (-) are independently rotatable with respect to each other. The invention further comprises electrical generators (G-G) mounted on each of the shafts (-) of the at least three spools (-), the output power of the generators being independently controllable and at least 60 percent of a total output power supplied to said load () in a form of electrical and rotational power is generated by the at least three generators (G-G) in the form of electrical energy.
