Duty Cycle (Option C61); Black Start (Option E05); Brake After Phase Shifter Operation (Option E08) - Siemens SINAMICS GL150 Operating And Installation Instructions

3.5.3

Duty cycle (option C61)

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.

It can be derived from the load cycles that the starting frequency converter is not dimensioned
for continuous operation at nominal power.
3.5.4

Black start (option E05)

This software option is required when starting with an auxiliary diesel so that starting is possible
with a reduction in the power drawn from the starting converter. If necessary, you must
parameterize limits and times deviating from the standard.
3.5.5

Brake after phase shifter operation (option E08)

With this software option, the generator is decelerated by the starting converter. The generator
can then be recoupled with the turbine.
