Figure 7-163 Power-Criterion Checking at Phi (power criterion) > 0
The power criterion contains the check of the current criterion and of the power-angle criterion.
You can determine whether to check the power criterion or not by setting the Power criterion parameter.
The power criterion is carried out only when the Power criterion parameter is set to yes.
The working method of the current criterion and of the power-angle criterion differ at Phi (power crite-
rion) ≤ 0 and Phi (power criterion) > 0.
