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
