3.5.5
Phase shifter start (option E07)
The generator that is decoupled from the gas turbine is accelerated to a speed slightly above
the synchronous speed via the starting converter. The starting converter is switched off
automatically once the speed setpoint is reached. The speed setpoint is approx. 10% above the
synchronous speed.
After the starting converter has been disconnected, the generator is excited to the rated voltage
and is synchronized with the line at a synchronous speed during runout. Once the generator
has been successfully synchronized with the line, positive or negative reactive power is
generated with the static excitation equipment.
3.5.6
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.
3.5.7
Plug connection between the starting converter and excitation equipment (option
G57)
Three plug connections are provided in the cutout in the side panel. This is used to connect the
power unit of the starting converter with the open-loop control cabinet of the excitation
equipment. The sockets are permanently installed in the open-loop control cabinet side panel.
The corresponding connectors in the converter can be freely connected to the terminals with
the adequate lengths provided.
The connectors are defined for the following signal and supply voltages:
