09 ACTUAL SIGNALS
Signals from the line converter.
09.12 LCU ACT SIGNAL 1 Line converter signal selected by par. 95.08 LCU PAR1 SEL. 1 = 1 106
09.13 LCU ACT SIGNAL 2 Line converter signal selected by par. 95.09 LCU PAR2 SEL. 1 = 1 110
95 HARDWARE SPECIF
Line converter references and actual signal selections.
95.06 LCU Q POW REF 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 1.09 POWER:
0
-10000 ... +10000 Setting range. 1 = 1
95.07 LCU DC REF (V) DC voltage reference for line converter i.e. the value for par. 23.01
DC VOLT REF. 0
0 … 1100 Setting range in volts. 1 = 1 V
95.08 LCU PAR1 SEL Selects the line-side converter address from which actual signal
09.12 LCU ACT SIGNAL 1 is read. 106
0 … 10000 Parameter index. 1 = 1
95.09 LCU PAR2 SEL Selects the line-side converter address from which actual signal
09.13 LCU ACT SIGNAL 2 is read. 110
