System control loop
With the help of the "System control loop" setting option, the relevant reactive power
procedure can be used for control purposes (open control loop; selection of control
loop
"OFF") or regulation purposes (closed control loop; selection of system control
loop
"ON"). Enabling a system control loop provides compensations for
inconsistencies between production and the grid connection point (GCP), which occur
due to the reactive power requirement of medium voltage cables and the transformer.
