If you have routed the voltage transformers to the measuring points, set the corresponding transformer data
in the System data.
In the FG Circuit breaker, under General, set the rated voltage that is used as a reference for percentage-
value scaling.
Siemens recommends routing the functional measured values into the fault record in addition to the logical
signals. Route at least the functional measured values
(_:2311:300) dV
,
(_:2311:301) df
, and
(_:
2311:302) dα
into the fault record. This allows you to document the commissioning and subsequently the
quality of synchronization.
The asynchronous operating mode defines the automatic synchronization of generators. For this reason, the
parameters for this operating mode are described in the following sections.
You can find the basic parameters in the setting sheet for the Syn./Asy.bal. stage in the General block. The
default settings for the parameters are typical values. You can use the default settings if the transformer has a
secondary rated voltage of 100 V.
