Generator Reactive Power Limitations
A reactive power control (kvar or power factor) can cause an overload or damage of the
generator. To avoid this the easYgen provides a 2-step protection:
⚙
1. ▷
The own absolute generator current is monitored with an percentage setting related to
rated current input (ID
). The easYgen limits or controls down the excitation
) is not exceeded.
2. ▷
The inductive reactive power outcome of the own generator is limited according to the
configuration of ID
.
Or:
The inductive reactive power income of the own generator is limited according to the
configuration of ID
.
