Description
3.5 Options
It can be derived from the load cycles that the starting frequency converter is not dimensioned
for continuous operation at nominal power.
3.5.28
Duty cycle (option C64)
The starting frequency converter is dimensioned in such a way that the specified duty cycles can
be performed. The duty cycles are possible with the described operating modes without thermal
overload at maximum ambient temperature.
The gas turbine is started in the "normal start" operating mode. The gas turbine is partly started
with upstream ventilation of the exhaust gas section and the boiler.
