Load and/or Var Sharing
Parameter 77
Active power
load-share ON
kW/kvar sharing: load sharing ON/OFF
ON................ Real power is shared between multiple generators operating in paral-
lel. The generator outputs are distributed depending on the config-
ured value. The subsequent screens of this function are displayed.
OFF.............. No real power sharing is carried out, and the subsequent screens of
this function are not displayed.
Parameter 78
Loadshare factor
active pow. 00%
kW/kvar sharing: reference variable kW 10 to 99 %
Increasing the load share factor increases the priority of the primary control vari-
able to the control. The lower the factor is configured, the greater the priority of the
secondary control variable.
Definition "Primary control variable"
• • Isolated operation = frequency
• • Mains parallel operation = real power (at the mains interchange point)
•
Definition "Secondary control variable"
• • Isolated operation = real power related to the other generators
• • Mains parallel operation = real power related to the other generators
The smaller this factor the higher the priority to equally share the load to all genera-
tors.
Parameter 79
Reactive power
Load-share ON
kW/kvar sharing: var sharing ON/OFF
ON................ Reactive power is shared between multiple generators operating in
parallel. The generator outputs are distributed depending on the con-
figured value. The subsequent screens of this function are displayed.
OFF.............. No reactive load sharing is carried out, and the subsequent screens of
this function are not displayed.
Parameter 80
Loadshare factor
reacte pow. 00%
kW/kvar sharing: reference variable kvar 10 to 99 %
Increasing the load share factor increases the priority of the primary control vari-
able (the voltage) to the control. The lower the factor is configured, the greater the
priority of the secondary control variable (generator reactive power). Var sharing is
activated during isolated parallel operating only.
