Reactive power characteristic curve
Overview
92
The following voltage limits can be changed:
Upper disconnection value
n
Lower disconnection value
n
The disconnection value relates to the average value of the
1)
voltage.
The reactive power characteristic curve must be set during initial
commissioning if this is prescribed for the previously selected
country. The following applies:
3 characteristic curves are available for selection (Fig. left):
n
– Default. char. curve (pre-defined)
– Enter char. curve (manually adjustable)
– Char. curve cos φ = 1 (pre-defined)
After configuration, the characteristic curve is displayed as a
n
graph (example in Fig. left).
① x-axis, output power P in %
② y-axis, phase shift cos φ
③ Nodes (in example: 4 nodes)
④ Arrow symbol
⑤ Arrow symbol
