Special Purpose Utility-Interactive - Fronius Symo 10.0-3 208-240 Installationshandbuch

Special Purpose Utility-Interactive

This unit has been evaluated according to IEEE1547 and IEEE1574.1 utility interconnection protective functions.
When "Special Purpose Utility-Interactive" (SPUI) setup will be activated, the inverter does not comply to these
standards anymore because islanding function will be disabled, frequency and voltage depending power reduc-
tion will be activated and the frequency and voltage limits will be changed.
Frequency Dependent Power Reduction (FDPR): When the specified grid frequency limit value is exceeded, the
effective power is reduced according to a defined gradient.
Voltage Dependent Power Reduction (VDPR): When the specified grid voltage limit value is exceeded, the ma-
ximum effective power is reduced. The power is reduced by a specified gradient according to the phase with the
highest voltage.
The field adjustable trip points can be set at the PROFI Service Menu. The access code will be provided by Fro-
nius upon request.
For detailed information ask your national Technical Support team (TSN).
