Connection Functions (With Induction/Asynchronous Generators Only)
Parameter 150
Switching-on GCB
ON
Connection of the GCB ON/OFF
ON ................ Generator frequency control is performed with the set point of the
mains frequency. The GCB is closed after meeting all connection cri-
teria listed below. The subsequent screens of this function are dis-
played.
OFF .............. The GCB is not closed. The subsequent screens of this function are
not displayed.
Parameter 151
Switching-on GCB
df max 0.00Hz
Max. perm. diff. frequency for GCB connection (pos. slip) 0.05 to 9.99 Hz
The prerequisite for issuing a close command is the monitored generator frequency
may deviate from the generator rated frequency by no more than this value. This
value specifies the upper frequency limit (positive value corresponds to positive
slip  generator frequency is higher than the busbar frequency in the case of GCB
synchronization).
Parameter 152
Switching-on GCB
df min -0,00Hz
Min. perm. diff. frequency for GCB connection (neg. slip) 0.0 to-9.99 Hz
The prerequisite for issuing a close command is the monitored generator frequency
may deviate from the generator rated frequency by no more than this value. This
value specifies the lower frequency limit (negative value corresponds to negative
slip  generator frequency is less than the busbar frequency in the case of GCB
synchronization).
Parameter 153
Switching-on GCB
T.impuls >0.00s
Time pulse for the GCB 0.02 to 0.26 s
The duration of the close pulse can be adjusted to the breaker.
Parameter 154
Automat.breaker
deblocking ON
Automatic circuit breaker deblocking ON/OFF
ON ................ Prior to each close pulse, a "Command: open GCB", or "Command:
open MCB" is issued for 1 second. A close signal is then enabled un-
til the breaker is closed.
OFF .............. Initialization of the circuit breaker closing is performed only by the
close pulse. No open pulse is issued prior to the close pulse.
