LCU ACT SIGNAL 1
Line-side converter signal selected by par. 95.08 LCU PAR1 SEL.

95 HARDWARE SPECIF
Line-side converter references and actual signal selections.
95.06
LCU Q PW REF
Reactive power reference for the line-side 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 1.09 POWER:

-10000 ... +10000
Setting range.
1 = 1
95.07
LCU DC REF
DC voltage reference for line converter i.e. the value for parameter
23.01 DC VOLT REF.
0
0 … 1100
Setting range in volts.
1 = 1 V
95.08
LCU PAR1 SEL
Selects the line converter address from which actual signal 9.12
LCU ACT SIGNAL 1 is read.
