Parameter Description Unit
Iac max Maximum admissible mains current (per shift) A
Iac mean max Maximum permissible DC-ratio of the fed-in system current A
Pac max Maximum effective power to be fed W
S max Maximum apparent power to be fed. VA
Island detection Immediate grid disconnection when island operation detected Inactive/on
Restart delay Delay time before grid reconnection upon previous failure-related grid
disconnection.
s
Pac progression Maximum increase of the effective power during grid reconnection
upon previous failure-related grid disconnection.
%/min
Mains check Additional monitoring before connecting to the grid Inactive/on
- Vac MC max Maximum admissible mains voltage at mains check V
- Vac MC min Minimum admissible mains voltage at mains check V
- f MC max Maximum admissible mains frequency at mains check Hz
- f MC min Minimum admissible mains frequency at mains check Hz
- t MC monitoring Duration of mains check s
Ierr max Maximum permissible fault current (effective value) on
the DC end
mA
P(f)-Mode Mode of the frequency-dependent power reduction
2: Operation on the nominal line / 3: Power increase according to
parameter Re-increase / Off: P(f) mode is switched offt
2/3/Off
- Reduction Reduction of effective power Pac in P(f) mode %/Hz
- f start Starting frequency of the P(f)-Mode Hz
- Re-increase Maximum increase to the maximum effective power Pac max after the
P(f) mode was exited.
%/min
Q-Mode
Selected reactive power mode: off, cosφ, cosφ(Pac), Q, or Q(Uac)
-
- Vac Lock Switch with hysteresis behaviour for the Q-Mode. When the switch is
activated, the selected reactive power mode is switched on and/or off
according to the limit values Vac Lock-In and Vac Lock-Out.
Inactive/on
- Vac Lock-In Upper limit value of the mains voltage for Vac Lock. Vac Lock switches
on the selected reactive power mode.
V
- Vac Lock-Out Lower limit value of the mains voltage for Vac Lock. Vac Lock switches
off the selected reactive power mode (cosφ = 1).
