Type of characteristic curve section
Using this menu item a characteristic curve specified by the grid operator can be stored. In principle a dis-
tinction is made here between a 2 point and a 4 point characteristic curve.
2-point characteristic curve
By selecting "2-point characteristic curve" it is possible to define a characteristic curve using two points.
Procedure
•
Select Variable reactive power via the characteristic curve Q(U)
•
Activate the
•
2-point characteristic curve
Select
•
Define the
check in front of inductive/under-excited.
•
SAVE the settings.
The characteristic curve displayed changes according to the values entered.
4-point characteristic curve
By selecting "4-point characteristic curve" it is possible to define a characteristic curve using four points.
Procedure:
•
Select variable reactive power via the characteristic curve Q(U)
•
Activate the
•
4-point characteristic curve
Select
•
Define the
check in front of inductive/under-excited.
•
SAVE the settings.
The characteristic curve displayed changes according to the values entered.
