Actual signals and parameters
Description
Signals from the line converter.
Line converter signal selected by par. 95.08 LCU PAR1 SEL.
Line converter signal selected by par. 95.09 LCU PAR2 SEL.
Description
Line converter references and actual signal selections.
Reactive power reference for the line converter i.e. the value for
par. 24.02 Q POWER REF2 in the IGBT Supply Control Program.
Scaling example 1: 10000 equals to a value of 10000 of
parameter 24.02 Q POWER REF2 and 100% of par. 24.01 Q
POWER REF (i.e. 100% of the converter nominal power given in
par. 04.06 CONV NOM POWER) when par. 24.03 Q POWER
REF2 SEL is set to PERCENT.
Scaling example 2: Par. 24.03 Q POWER REF2 SEL is set to
kVAr. A value of 1000 of par. 95.06 equals to 1000 kVAr of par.
24.02 Q POWER REF2. Value of par. 24.01 Q POWER REF is
then 100 · (1000 kVAr divided by converter nominal power in
kVAr)%.
Scaling example 3: Par. 24.03 Q POWER REF2 SEL is set to
PHI. A value of 10000 of par. 95.06 equals to a value of 100 deg
of parameter 24.02 Q POWER REF2 which is limited to 30 deg.
The value of par. 24.01 Q POWER REF will be determined
approximately according to the following equation where P is read
from actual signal 1.06 POWER:
