Application No. 08/460,086
identifies that the system makes use of a variable speed gas
turbine, which allows for high power output at elevated
temperature. On page 8 of the specification, Appellant
describes the generator as one where there is an alternating
current applied to the rotor windings. Appellant states that
by controlling the frequency of the alternating current
supplied to the rotor windings the frequency of the power
generated at the stator can be controlled. Appellant
identifies on pages 8 and 9 of the specification that by
controlling the alternating current applied to the rotor
windings, a constant frequency power is generated by the
variable speed turbine generator. Appellant identifies on
page 10 of the specification that the fuel flow to the gas
turbine is responsive to the load demand. As Appellant shows
in figure 3, plot 120, this results in the turbine speed
increasing in response to increase load and ambient
temperature. Appellant identifies on page 10 of the
specification that by operating the turbine at increased speed
at higher ambient temperature, the compressor will intake more
air and allow the turbine to maintain a high power output.
Appellant also discloses on page 10 of the specification that
