90ParametersNo. Name/Value Description FbEq Def.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 forpar. 24.02 Q POWER REF2 in the IGBT Supply Control Program.Scaling example 1: 10000 equals to a value of 10000 of parameter24.02 Q POWER REF2 and 100% of par. 24.01 Q POWER REF(i.e. 100% of the converter nominal power given in par. 04.06CONV NOM POWER) when par. 24.03 Q POWER REF2 SEL isset 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 QPOWER 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 ofparameter 24.02 Q POWER REF2 which is limited to 30 deg. Thevalue of par. 24.01 Q POWER REF will be determinedapproximately according to the following equation where P is readfrom actual signal 1.06 POWER:0Pcos30 = -- =SP-----------------------P 2 + Q 2S30 degPPositive reference 30 deg denotes capacitive load.Negative reference 30 deg denotes inductive load.QPar. 95.06Par. 24.02-30 -10 030 (deg)-10000 -3000 -1000 0 1000 3000 +1000010-10000 ... +10000 Setting range. 1 = 195.07 LCU DC REF (V) DC voltage reference for line converter i.e. the value for par. 23.01DC VOLT REF.0 … 1100 Setting range in volts. 1 = 1 V95.08 LCU PAR1 SEL Selects the line-side converter address from which actual signal09.12 LCU ACT SIGNAL 1 is read.0 … 10000 Parameter index. 1 = 195.09 LCU PAR2 SEL Selects the line-side converter address from which actual signal09.13 LCU ACT SIGNAL 2 is read.0 … 10000 Parameter index. 1 = 10106110Actual signals and parameters
